Welcome to Stuff 5 00:00:14,640 --> 00:00:23,239 Speaker 1: you Should Know from house Stuff Works dot com. Hey, 6 00:00:23,320 --> 00:00:26,759 Speaker 1: you're welcome to the podcast. I'm Josh Clark. There's Charles W. 7 00:00:26,960 --> 00:00:31,200 Speaker 1: Chuck Bryant, and Jerry's over there, which means time for 8 00:00:31,360 --> 00:00:35,559 Speaker 1: Stuff you should know. The Jackhammer edition coming at you. 9 00:00:35,760 --> 00:00:40,479 Speaker 1: That's right, the most annoying, one of the most annoying sounds. 10 00:00:40,560 --> 00:00:44,400 Speaker 1: I know you hate the leaf flower. Yeah, it's established. 11 00:00:44,760 --> 00:00:47,840 Speaker 1: I think the leaf jack camera right there? If sure, Yeah, 12 00:00:48,200 --> 00:00:50,240 Speaker 1: but we don't live in New York. If we lived 13 00:00:50,240 --> 00:00:52,720 Speaker 1: in New York, jackhammera B number one. I feel like 14 00:00:52,760 --> 00:00:54,600 Speaker 1: I've never stayed in a hotel in New York where 15 00:00:54,600 --> 00:00:58,120 Speaker 1: there wasn't a jack below me, not even a chance. 16 00:00:58,400 --> 00:01:03,640 Speaker 1: Every single time leaf blower. It's a lot more frequent 17 00:01:03,720 --> 00:01:06,440 Speaker 1: down here in Atlanta than Jack Cameron. A lot of 18 00:01:06,520 --> 00:01:09,960 Speaker 1: leaf blowers in New York City, not a lot of leaves. Well, 19 00:01:10,040 --> 00:01:13,240 Speaker 1: that's not necessarily true. Been some where you are. Uh 20 00:01:13,280 --> 00:01:16,319 Speaker 1: so we don't usually um shout out to thank you 21 00:01:16,680 --> 00:01:19,880 Speaker 1: at the beginning of an episode. But we got a 22 00:01:19,920 --> 00:01:22,920 Speaker 1: couple of gifts that are so special we want to 23 00:01:22,920 --> 00:01:26,919 Speaker 1: do that. So Peter O'Donnell in the gang at built 24 00:01:27,040 --> 00:01:31,520 Speaker 1: Sharp knives. B I LT Sharp out of Philly. H 25 00:01:32,319 --> 00:01:35,520 Speaker 1: sent us sent me a chef's knife, sent you a 26 00:01:35,600 --> 00:01:40,640 Speaker 1: filet knife. Beautiful and it's one of the most gorgeous 27 00:01:40,800 --> 00:01:45,720 Speaker 1: pieces of like handmade craftsmanship I've ever seen. It's amazing. 28 00:01:46,000 --> 00:01:49,240 Speaker 1: I cannot wait to catch a fish. Oh dude, I 29 00:01:49,280 --> 00:01:51,320 Speaker 1: can't wait for that for you cut that thing open 30 00:01:53,240 --> 00:01:57,720 Speaker 1: after it's dead. Uh really, you can't lock the head 31 00:01:57,720 --> 00:02:01,120 Speaker 1: off while it's still alive, and you're supposed to. You're 32 00:02:01,120 --> 00:02:03,920 Speaker 1: supposed to hit it with a hammer. I think some 33 00:02:03,960 --> 00:02:07,360 Speaker 1: people do. Um, I do not. These things are gorgeous. 34 00:02:07,360 --> 00:02:09,520 Speaker 1: I mean the blade itself, I mean they hand make these, 35 00:02:09,560 --> 00:02:12,280 Speaker 1: the handle, the weight, it's just it's a piece of art. 36 00:02:12,880 --> 00:02:15,639 Speaker 1: And not only that, it is the sharpest thing I've 37 00:02:15,639 --> 00:02:19,840 Speaker 1: ever seen in my life. It's like dangerous. Um, well, 38 00:02:19,840 --> 00:02:22,800 Speaker 1: I don't want to you know, it's dangerous. They're knives. 39 00:02:22,919 --> 00:02:27,480 Speaker 1: They're supposed to be sharp, but wield it with respect. 40 00:02:27,639 --> 00:02:32,240 Speaker 1: Well yeah, well they're respectable knives. Um. You can actually 41 00:02:32,280 --> 00:02:35,840 Speaker 1: go into Tumbler. You can just search hashtag knives. You 42 00:02:35,880 --> 00:02:40,240 Speaker 1: should know one word and it uh it chronicles and 43 00:02:40,360 --> 00:02:44,720 Speaker 1: pictures and short captions or brief captions the process of 44 00:02:44,760 --> 00:02:47,399 Speaker 1: them making our knives. It's awesome. Yeah, it's just really neat. 45 00:02:47,400 --> 00:02:50,760 Speaker 1: And I just love like handcrafting and forging steel, like 46 00:02:50,840 --> 00:02:53,840 Speaker 1: those are lost arts in a lot of ways, and um, 47 00:02:53,880 --> 00:02:57,160 Speaker 1: they're doing it right man, They're really beautiful. So anyway, 48 00:02:57,440 --> 00:02:59,959 Speaker 1: thank you, Yeah, thank you guys. Yeah, thanks people. Was 49 00:03:00,040 --> 00:03:03,520 Speaker 1: really cool. So jack hammers, yeah, jack hammers. If they 50 00:03:03,520 --> 00:03:06,680 Speaker 1: were sharpest built sharp knives, they'd be onto something. But 51 00:03:07,000 --> 00:03:09,160 Speaker 1: I don't know if it would work quite the same 52 00:03:09,600 --> 00:03:13,680 Speaker 1: not so. Um, yes, it's true, we are actually talking 53 00:03:13,720 --> 00:03:18,000 Speaker 1: about jack hammers. And yes, it's true that jack hammers 54 00:03:18,040 --> 00:03:20,919 Speaker 1: are about what you think they are. But they're also 55 00:03:21,160 --> 00:03:23,240 Speaker 1: kind of interesting when you start to look into them, 56 00:03:23,320 --> 00:03:26,399 Speaker 1: right yeah, well yes, so think about I didn't realize this. 57 00:03:26,400 --> 00:03:29,600 Speaker 1: This article points it out. Jack hammer is a hammer 58 00:03:29,639 --> 00:03:34,160 Speaker 1: and a chisel, but it's a hardcore hammer and chisel. Yeah, 59 00:03:34,600 --> 00:03:37,320 Speaker 1: and it takes out of the equation largely the human 60 00:03:37,760 --> 00:03:41,520 Speaker 1: who's back and shoulder muscles have to be involved in 61 00:03:41,560 --> 00:03:44,160 Speaker 1: every single strike of that hammer. And chisel. You're talking 62 00:03:44,240 --> 00:03:48,600 Speaker 1: John Henry and the sledge hammer. Yes, exactly, because prior 63 00:03:48,680 --> 00:03:53,640 Speaker 1: to the advent of the jackhammer, about that fifties, by 64 00:03:53,960 --> 00:03:57,000 Speaker 1: the turn of the last century, we had jack hammers 65 00:03:57,080 --> 00:04:01,920 Speaker 1: kind of down pat um. It was sledge hammers and 66 00:04:02,000 --> 00:04:06,440 Speaker 1: pick axes to remove rock. It was a real deal. 67 00:04:06,880 --> 00:04:10,480 Speaker 1: That was like it killed people, like it literally could 68 00:04:10,640 --> 00:04:13,240 Speaker 1: kill you with that kind of work. Yeah, I mean, 69 00:04:13,280 --> 00:04:17,280 Speaker 1: mining is still a very dangerous job, but pre Industrial 70 00:04:17,360 --> 00:04:24,920 Speaker 1: Revolution mining was no fun um, dangerous, deadly, and even 71 00:04:24,960 --> 00:04:28,280 Speaker 1: if you didn't die, it's just brutal, brutal back baking work, 72 00:04:28,480 --> 00:04:30,840 Speaker 1: baking work, slinging a sledgehammer. Yeah, you ever slung a 73 00:04:30,880 --> 00:04:34,880 Speaker 1: sledge It's the worst. It's it's hard work. You ever 74 00:04:34,960 --> 00:04:38,440 Speaker 1: used the jackhammer? No, I haven't. It's awful. Well, that's 75 00:04:38,440 --> 00:04:41,760 Speaker 1: the thing. It's it's better than the sledgehammer. Yeah, well 76 00:04:41,800 --> 00:04:45,039 Speaker 1: in some ways, but it's brutally difficult. It is. It's 77 00:04:45,080 --> 00:04:47,640 Speaker 1: probably one of the most brutal tools you can use 78 00:04:47,720 --> 00:04:50,880 Speaker 1: on any kind of site and for any kind of project. 79 00:04:51,200 --> 00:04:53,159 Speaker 1: There aren't that many tools that they're they're gonna take 80 00:04:53,160 --> 00:04:56,039 Speaker 1: as much out of you as the jackhammer. It's tough 81 00:04:56,080 --> 00:04:58,839 Speaker 1: on your body. Yeah, because they weigh about a hundred pounds, 82 00:04:58,960 --> 00:05:02,680 Speaker 1: like a new normal heavy duty jackhammer weighs about a 83 00:05:02,720 --> 00:05:05,480 Speaker 1: hundred pounds. You have to hold it in place upright, 84 00:05:05,760 --> 00:05:07,839 Speaker 1: because you don't want to jumping around, although it's probably 85 00:05:07,880 --> 00:05:10,599 Speaker 1: not going to anyway. It's it's designed not to jump around, 86 00:05:11,080 --> 00:05:13,760 Speaker 1: but you still have to. Um. You want to kind 87 00:05:13,760 --> 00:05:16,120 Speaker 1: of keep it in a fairly confined area, which means 88 00:05:16,160 --> 00:05:19,000 Speaker 1: you're using your muscle to steady it while it's going 89 00:05:19,080 --> 00:05:22,320 Speaker 1: up and down at a very very fast rate. Some 90 00:05:22,360 --> 00:05:26,320 Speaker 1: of those things, um impact with the ground one thousand 91 00:05:27,360 --> 00:05:30,920 Speaker 1: times a minute. Yeah, it's tough. It's it's the only 92 00:05:30,960 --> 00:05:37,320 Speaker 1: tool that and the hardwood floor UM skimmer, you know, 93 00:05:37,360 --> 00:05:41,040 Speaker 1: like the orbital floor cleaner. You can use that on it, 94 00:05:41,120 --> 00:05:43,680 Speaker 1: like put a standing pad on a hardwood floor, and 95 00:05:43,960 --> 00:05:46,360 Speaker 1: that thing and the sledge hammer. The only time I've 96 00:05:46,360 --> 00:05:49,080 Speaker 1: ever used tools that I felt like we're controlling me 97 00:05:49,640 --> 00:05:52,599 Speaker 1: and not me, not controlling the tool until you get it. 98 00:05:52,640 --> 00:05:55,640 Speaker 1: Once you get it, it's a little better. But at first, 99 00:05:55,720 --> 00:05:57,320 Speaker 1: when you first start to use it. You can rent 100 00:05:57,320 --> 00:06:00,120 Speaker 1: a jackhammer, you know, so you know, yeah, I mean, 101 00:06:00,120 --> 00:06:01,760 Speaker 1: if you want to bust up your driveway, you can 102 00:06:01,800 --> 00:06:04,640 Speaker 1: go do it yourself. If you're a fool, make sure 103 00:06:04,680 --> 00:06:07,479 Speaker 1: that you don't need the driveway anymore before you do that. 104 00:06:08,080 --> 00:06:09,760 Speaker 1: But um, once you get the hang of it, you 105 00:06:09,839 --> 00:06:11,719 Speaker 1: kind of can wield it a little bit. But it's tough. 106 00:06:11,760 --> 00:06:15,279 Speaker 1: I mean, it feels like I have no power or 107 00:06:15,320 --> 00:06:19,800 Speaker 1: control over this thing, right, I can imagine you know. So, Um, 108 00:06:20,600 --> 00:06:23,920 Speaker 1: it is a very difficult tool. But again, the alternative 109 00:06:24,040 --> 00:06:28,640 Speaker 1: is early death. And the other alternative, which is to 110 00:06:28,680 --> 00:06:30,760 Speaker 1: call someone to do it for you, is the best 111 00:06:31,240 --> 00:06:35,000 Speaker 1: option of the three. But so, say that you are um, 112 00:06:36,160 --> 00:06:40,159 Speaker 1: King Carlo Alberto of Sardinia and the years about eighteen 113 00:06:40,240 --> 00:06:44,880 Speaker 1: thirty something eighteen forty, and you want a train tunnel 114 00:06:44,960 --> 00:06:49,080 Speaker 1: built through a mountain, and the tunnel is gonna need 115 00:06:49,120 --> 00:06:53,479 Speaker 1: to be twelve kilometers long. You do call somebody else, 116 00:06:53,560 --> 00:06:56,440 Speaker 1: but that somebody else you call goes. I don't know 117 00:06:56,480 --> 00:06:59,520 Speaker 1: what to tell you, buddy. We could try pick axes 118 00:06:59,600 --> 00:07:01,520 Speaker 1: or whatever, but you're not still gonna be alive by 119 00:07:01,520 --> 00:07:04,480 Speaker 1: the time we finished. What can we do? And actually, 120 00:07:04,520 --> 00:07:07,280 Speaker 1: this call for a twelve kilometer long tunnel through a 121 00:07:07,320 --> 00:07:13,040 Speaker 1: mountain in Sardinia prompted the early um, the early forays 122 00:07:13,120 --> 00:07:17,320 Speaker 1: into developing pneumatic tools like a jackhammer. Yeah, in eighty 123 00:07:17,400 --> 00:07:21,000 Speaker 1: eight it got named Jonathan Couch built a what he 124 00:07:21,040 --> 00:07:24,040 Speaker 1: called a percussion drill, and this had a bit that 125 00:07:24,720 --> 00:07:27,200 Speaker 1: was it went through the piston of a steam engine, 126 00:07:27,680 --> 00:07:32,080 Speaker 1: so it was piston driven. Then, uh, contemporary Joseph Foul 127 00:07:32,120 --> 00:07:35,760 Speaker 1: actually attached it to the piston and then he started 128 00:07:35,800 --> 00:07:39,680 Speaker 1: in one using air which is pneumatic to power it. 129 00:07:40,280 --> 00:07:43,640 Speaker 1: But these were still attached to a piston. And it 130 00:07:43,680 --> 00:07:49,200 Speaker 1: wasn't until Charles Brady King when he actually has given 131 00:07:49,240 --> 00:07:57,640 Speaker 1: credit for inventing the traditional looking handheld, modern pneumatic powered jackhammer. Right, 132 00:07:57,680 --> 00:07:59,520 Speaker 1: and he gets a lot of credit for stuff that 133 00:07:59,840 --> 00:08:02,440 Speaker 1: was already built. Like a lot of people say he 134 00:08:02,520 --> 00:08:05,960 Speaker 1: was actually the inventor of the automobile. No he wasn't. Well, 135 00:08:06,000 --> 00:08:08,640 Speaker 1: he was the inventor of the gasoline powered automobile, No 136 00:08:08,760 --> 00:08:10,720 Speaker 1: he wasn't. He was the first guy in Detroit to 137 00:08:10,800 --> 00:08:13,800 Speaker 1: build and drive one around, and he did end up 138 00:08:14,160 --> 00:08:17,200 Speaker 1: inspiring and mentoring Ransom Olds and Henry Ford and some 139 00:08:17,280 --> 00:08:21,320 Speaker 1: other early car manufacturers and is almost single handily responsible 140 00:08:21,360 --> 00:08:25,520 Speaker 1: for making Detroit motor city. This guy, but he also 141 00:08:25,640 --> 00:08:29,760 Speaker 1: Stanley right, Uh, and what's from with it's freely. I 142 00:08:29,800 --> 00:08:31,720 Speaker 1: like that guy's stuff. What do you mean didn't he 143 00:08:31,760 --> 00:08:34,320 Speaker 1: get kicked out of Kiss? Oh? I think he was 144 00:08:34,360 --> 00:08:38,320 Speaker 1: sort of not invited back. Yeah. I think it's a 145 00:08:38,320 --> 00:08:41,760 Speaker 1: money move. They don't have to pay the nameless other 146 00:08:41,800 --> 00:08:44,000 Speaker 1: guitar player nearly as well. He was a founder of 147 00:08:44,040 --> 00:08:46,560 Speaker 1: the band, Right, How do you get kicked out like 148 00:08:46,640 --> 00:08:49,920 Speaker 1: that for money? I think Paul Stanley and Jean Simmons 149 00:08:49,920 --> 00:08:59,439 Speaker 1: probably own Kiss Incorporated. I know anyway, Um, Charles Brady King, Uh, 150 00:08:59,559 --> 00:09:01,760 Speaker 1: he wait Detroit on the map as far as auto 151 00:09:01,760 --> 00:09:05,199 Speaker 1: manufacturer goes. And he did do a lot of refining 152 00:09:05,240 --> 00:09:08,000 Speaker 1: of pneumatic tools, including the jackhammer, and he does hold 153 00:09:08,000 --> 00:09:10,040 Speaker 1: the pattern, he did hold the patent for it. Yeah, 154 00:09:10,040 --> 00:09:11,320 Speaker 1: and he had been at a lot of stuff. He 155 00:09:11,400 --> 00:09:15,040 Speaker 1: was a sharp guy. And the pneumatic the fact that 156 00:09:15,040 --> 00:09:19,760 Speaker 1: it's pneumatic, which means air powered, compressed air powered. Um 157 00:09:19,920 --> 00:09:25,359 Speaker 1: is the reason why most jackhammers today are still compressed 158 00:09:25,400 --> 00:09:29,840 Speaker 1: air powered. It's because of the mining application of it. 159 00:09:30,920 --> 00:09:34,840 Speaker 1: Like when you mind, you're releasing a lot of potentially 160 00:09:34,920 --> 00:09:39,600 Speaker 1: explosive gases, and uh, you can't have something like a 161 00:09:39,679 --> 00:09:43,559 Speaker 1: steam engine that's combustion powered down there yeah, or you 162 00:09:43,840 --> 00:09:48,400 Speaker 1: can't have an engine in there releasing exhaust. Um, and 163 00:09:48,520 --> 00:09:53,920 Speaker 1: you can't have a jackhammer that will spark a rock. Um. Well, 164 00:09:53,960 --> 00:09:56,679 Speaker 1: that might happen no matter what. Right, well, no, that's 165 00:09:56,720 --> 00:09:59,319 Speaker 1: what I'm saying. You can't have that among volatile gases. 166 00:09:59,520 --> 00:10:03,400 Speaker 1: Right You've air driven is the perfect key, because it 167 00:10:03,440 --> 00:10:06,959 Speaker 1: doesn't matter if that hoses a thousand feet long, You're 168 00:10:06,960 --> 00:10:09,679 Speaker 1: not gonna lose power because it's gonna be Yeah, it's 169 00:10:09,679 --> 00:10:12,480 Speaker 1: gonna be compressed air up against compressed air, and up 170 00:10:12,559 --> 00:10:15,200 Speaker 1: on the surface. You've got a diesel engine that's powering 171 00:10:15,200 --> 00:10:17,640 Speaker 1: a piston, just like in your car, and the piston 172 00:10:17,720 --> 00:10:19,839 Speaker 1: moves up and down the cylinder. As it moves down, 173 00:10:20,240 --> 00:10:23,600 Speaker 1: it compresses the air in the cylinder and pushes it 174 00:10:23,600 --> 00:10:26,000 Speaker 1: down into a storage tank where it sits his compressed 175 00:10:26,040 --> 00:10:28,160 Speaker 1: air and that's released out the other end through the 176 00:10:28,160 --> 00:10:30,719 Speaker 1: hose and it ends up into the jackhamer. And yeah, 177 00:10:30,800 --> 00:10:32,720 Speaker 1: no matter how far away it is, it's still going 178 00:10:32,760 --> 00:10:37,479 Speaker 1: to be just as powerful. And that compressed air is inflammable. 179 00:10:37,520 --> 00:10:39,160 Speaker 1: So you can be a happy minor all the live 180 00:10:39,240 --> 00:10:42,040 Speaker 1: long day. Well, buddy, you're getting excited. So that means 181 00:10:42,040 --> 00:10:44,240 Speaker 1: we need to take a break and uh, put this 182 00:10:44,360 --> 00:10:46,640 Speaker 1: pill under your tongue and we'll come back right after this. 183 00:11:07,160 --> 00:11:12,839 Speaker 1: How you feeling now, Relax good? I love the title 184 00:11:12,840 --> 00:11:17,240 Speaker 1: of this next section, Air powered destruction. Um. You can 185 00:11:17,360 --> 00:11:20,320 Speaker 1: get an electric jack hammer. If you've ever gone to 186 00:11:20,360 --> 00:11:24,240 Speaker 1: a hardware store, they have these kind of smaller handheld 187 00:11:25,240 --> 00:11:28,280 Speaker 1: jack hammers that, um, you can take up like your 188 00:11:28,320 --> 00:11:31,760 Speaker 1: bathroom floor tile pretty well with it plugging into the wall. 189 00:11:32,360 --> 00:11:35,600 Speaker 1: Has a little chisel bit on the end of it. Um, 190 00:11:35,640 --> 00:11:39,559 Speaker 1: But that's small. Beans. You can't do a driveway or 191 00:11:39,640 --> 00:11:43,319 Speaker 1: concrete or asphalt with with something like that tunnel through 192 00:11:43,320 --> 00:11:45,760 Speaker 1: a mountain in Sardinia. No, you need the big T 193 00:11:46,160 --> 00:11:49,400 Speaker 1: shaped jack camera. And here's one of the things that 194 00:11:49,440 --> 00:11:51,640 Speaker 1: didn't really occur to me. One of the reasons it 195 00:11:51,679 --> 00:11:55,320 Speaker 1: works so well is because it's so heavy. Right. It's 196 00:11:55,360 --> 00:11:57,320 Speaker 1: not like they say, well, let's make this thing way 197 00:11:57,480 --> 00:11:59,960 Speaker 1: fifteen pounds or twenty pounds and make it easier to run, 198 00:12:00,000 --> 00:12:02,840 Speaker 1: which they probably could. Yeah, you maybe could do that, 199 00:12:02,880 --> 00:12:04,720 Speaker 1: but it would jump all over the place. Yeah, you 200 00:12:04,720 --> 00:12:07,160 Speaker 1: want that thing super super heavy because that's part of 201 00:12:07,200 --> 00:12:09,559 Speaker 1: the power and forced behind it. That's right. So these 202 00:12:09,559 --> 00:12:12,480 Speaker 1: things are pneumatic, right, and just like on the compressed 203 00:12:12,679 --> 00:12:16,200 Speaker 1: air compressor up on the surface. When you're down in 204 00:12:16,200 --> 00:12:20,920 Speaker 1: the mine, they actually have a jackhammer, has a piston 205 00:12:21,080 --> 00:12:24,199 Speaker 1: in a piston in a cylinder in it, right, and 206 00:12:24,640 --> 00:12:27,840 Speaker 1: it's it's actually a really kind of simple When you 207 00:12:27,960 --> 00:12:31,160 Speaker 1: cut the thing open and draw a cross section of it, 208 00:12:31,200 --> 00:12:35,439 Speaker 1: which we did on our hands for crib sheets. Um, 209 00:12:35,960 --> 00:12:39,000 Speaker 1: you you you can see that. Really the whole mechanism 210 00:12:39,040 --> 00:12:43,120 Speaker 1: comes down to a trigger valve, right, that's right. So 211 00:12:43,160 --> 00:12:44,920 Speaker 1: what you have here is you got the pressure chamber. 212 00:12:45,400 --> 00:12:48,920 Speaker 1: The compressed air enters that chamber activates the trigger valve, 213 00:12:49,480 --> 00:12:52,360 Speaker 1: and it just because of the compressed air opens and 214 00:12:52,360 --> 00:12:55,360 Speaker 1: shuts really fast, right, and so the trigger valve moves 215 00:12:55,400 --> 00:12:59,360 Speaker 1: the air either above the piston or when it closes, 216 00:12:59,720 --> 00:13:03,200 Speaker 1: the air goes down below the piston, which means chisel 217 00:13:03,240 --> 00:13:05,760 Speaker 1: goes up, chizzle goes down, right, because the piston is 218 00:13:05,840 --> 00:13:10,000 Speaker 1: striking the top of that chisel bit, driving it downward 219 00:13:10,280 --> 00:13:12,880 Speaker 1: when the compressed air comes in and pushes the piston down. 220 00:13:13,240 --> 00:13:16,480 Speaker 1: And then when the valve closes and the air goes 221 00:13:16,559 --> 00:13:19,520 Speaker 1: underneath the piston, there's also a spring in there that 222 00:13:20,000 --> 00:13:22,680 Speaker 1: brings the drill bit back up because it wouldn't work 223 00:13:22,760 --> 00:13:25,440 Speaker 1: very well if you knock it down. They had to 224 00:13:25,480 --> 00:13:29,480 Speaker 1: go down and reset it, and apparently the earliest um, 225 00:13:29,559 --> 00:13:34,760 Speaker 1: the earliest jackhammered had that very designature that was it 226 00:13:34,800 --> 00:13:37,200 Speaker 1: like it goes bam and then you definitely like reset 227 00:13:37,240 --> 00:13:39,520 Speaker 1: it bam and then reset it and they're like, this 228 00:13:39,559 --> 00:13:43,119 Speaker 1: isn't gonna work. Yeah, that's sort of like the pneumatic 229 00:13:43,880 --> 00:13:47,640 Speaker 1: cattle punch that they that what's his face used in 230 00:13:47,720 --> 00:13:51,360 Speaker 1: No Country for old Man. It's exactly like that. Not 231 00:13:51,520 --> 00:13:54,040 Speaker 1: very good if you're trying to bust up concrete, but 232 00:13:54,120 --> 00:13:57,599 Speaker 1: good if you want to put on a cow's It 233 00:13:57,640 --> 00:14:00,839 Speaker 1: doesn't stunn them. It does the eternal stunt. I think 234 00:14:00,880 --> 00:14:04,680 Speaker 1: it's stuns a cow and then they kill them. Oh 235 00:14:04,720 --> 00:14:06,840 Speaker 1: I thought it they put it into the brain to 236 00:14:06,920 --> 00:14:09,360 Speaker 1: kill the cow. I don't think he actually, I think 237 00:14:09,360 --> 00:14:11,880 Speaker 1: it can and probably does sometimes, but I think the 238 00:14:11,920 --> 00:14:14,040 Speaker 1: main purpose of it is to stun the cow, so 239 00:14:14,120 --> 00:14:16,560 Speaker 1: it's not like it's just dazed and out of it 240 00:14:16,559 --> 00:14:21,000 Speaker 1: when it when they kill it. Oh yeah yeah. Uh. 241 00:14:21,240 --> 00:14:24,840 Speaker 1: Hydraulic jack hammers, it's the same, uh jackhammera would kill 242 00:14:24,840 --> 00:14:30,240 Speaker 1: a cow. Hydraulics use fluid, same principle, but it doesn't 243 00:14:30,320 --> 00:14:33,360 Speaker 1: use air. And if you've ever seen the they have 244 00:14:33,440 --> 00:14:36,000 Speaker 1: jackhammers you can that are really large that you can't 245 00:14:36,000 --> 00:14:38,760 Speaker 1: handle as a person. That it's like attached to a 246 00:14:38,800 --> 00:14:41,720 Speaker 1: bacco or something that's for big, big jobs. And those 247 00:14:41,720 --> 00:14:46,000 Speaker 1: are usually um hydraulic and pneumatic, but probably not every time. 248 00:14:46,880 --> 00:14:49,520 Speaker 1: I'm sure someone in the construction industry will correct me 249 00:14:49,520 --> 00:14:51,560 Speaker 1: on that. Well, I went and looked. And if you 250 00:14:51,680 --> 00:14:55,280 Speaker 1: go on Alibaba that you know that's I has everything 251 00:14:55,920 --> 00:14:59,640 Speaker 1: and they have hydraulic jackhammers for sale. What's Ali Baba? 252 00:14:59,840 --> 00:15:03,680 Speaker 1: That sky Mall it's like China's Amazon, but they sell 253 00:15:04,600 --> 00:15:08,440 Speaker 1: everything on it. It's nothing like Skymall. Do you think 254 00:15:08,440 --> 00:15:11,200 Speaker 1: everything's like Skymallas because you want Skymall to come back? 255 00:15:11,480 --> 00:15:14,760 Speaker 1: That sure do? Um, But they it did seem like 256 00:15:14,800 --> 00:15:18,320 Speaker 1: all of the back ho attached um jack hammers were 257 00:15:18,400 --> 00:15:23,640 Speaker 1: hydraulic that I saw. All right, Well, um, here's what 258 00:15:23,720 --> 00:15:28,600 Speaker 1: happens at a thousand hits per minute. That chisel bit 259 00:15:29,040 --> 00:15:31,280 Speaker 1: and if you're breaking up rock, there are different kinds 260 00:15:31,280 --> 00:15:33,840 Speaker 1: of bits. A pointy bit if you're breaking up like 261 00:15:33,880 --> 00:15:37,040 Speaker 1: a driveway or something is really good, or you can 262 00:15:37,120 --> 00:15:40,120 Speaker 1: use a flat bit for other applications. So, yeah, if 263 00:15:40,120 --> 00:15:42,120 Speaker 1: you're breaking up a driveway and all you want is 264 00:15:42,160 --> 00:15:44,920 Speaker 1: for the driveway to go bye by, Yeah, the pointy 265 00:15:44,920 --> 00:15:47,680 Speaker 1: bits the one you want because it's not a controlled cut. 266 00:15:48,360 --> 00:15:53,080 Speaker 1: The the like a flathead screw drivers style bit is 267 00:15:53,120 --> 00:15:55,040 Speaker 1: the kind that where you can really kind of control 268 00:15:55,120 --> 00:15:58,240 Speaker 1: where the cracking goes, right, or if you wanna uh, 269 00:15:58,800 --> 00:16:00,480 Speaker 1: like I said, if you're taking up your floor tile 270 00:16:00,480 --> 00:16:02,920 Speaker 1: and you have the handheld version, that's what you want 271 00:16:02,960 --> 00:16:05,800 Speaker 1: to discoot it underneath the tile and chip it up. 272 00:16:05,920 --> 00:16:11,200 Speaker 1: And there's actually there's like, um, some insane mathematicians have 273 00:16:11,360 --> 00:16:14,240 Speaker 1: actually like tried to figure out how you can predict 274 00:16:14,640 --> 00:16:18,400 Speaker 1: how cracks propagate. Yeah, there's like a um for the 275 00:16:18,440 --> 00:16:22,200 Speaker 1: most efficient jackhammering pretty much like what bit will work best, 276 00:16:22,280 --> 00:16:23,880 Speaker 1: and like where to place it and how to how 277 00:16:23,920 --> 00:16:27,000 Speaker 1: to use it. But um, one of the things that 278 00:16:27,120 --> 00:16:32,360 Speaker 1: I didn't understand before is that when you are jackhammering, 279 00:16:32,840 --> 00:16:39,760 Speaker 1: you you are creating different types of uh uh flaws 280 00:16:39,840 --> 00:16:43,440 Speaker 1: basically in this solid stay concrete structure, right, And when 281 00:16:43,480 --> 00:16:45,760 Speaker 1: you're doing that, the first flaw you're doing, the first 282 00:16:45,760 --> 00:16:49,400 Speaker 1: flaw you're creating is this um kind of surface powder 283 00:16:50,040 --> 00:16:53,000 Speaker 1: that the the initial chips you're making are actually powder 284 00:16:53,160 --> 00:16:57,280 Speaker 1: rizing and and congealing around the drill bit, right, and 285 00:16:57,600 --> 00:17:02,320 Speaker 1: that powder actually transmit it's the impact of the jackhammer 286 00:17:02,840 --> 00:17:06,399 Speaker 1: throughout the rest of the concrete pad in that immediate area, 287 00:17:06,720 --> 00:17:09,639 Speaker 1: and that actually starts to create cracks. So you think, well, 288 00:17:10,440 --> 00:17:12,879 Speaker 1: it's just the drill bit creating crack it gets in 289 00:17:12,920 --> 00:17:17,000 Speaker 1: there enough. Actually no, it's it's generating like these different 290 00:17:17,040 --> 00:17:20,920 Speaker 1: materials from the very concrete itself, and it's using those 291 00:17:20,960 --> 00:17:25,560 Speaker 1: materials to distribute the force and create cracks that ultimately 292 00:17:25,600 --> 00:17:28,760 Speaker 1: start to spread and propagate. And as they spread and propagate, 293 00:17:28,880 --> 00:17:31,080 Speaker 1: they get bigger and bigger, and then a chip comes off, 294 00:17:31,440 --> 00:17:33,760 Speaker 1: and when the chip comes off, the amount of force 295 00:17:33,840 --> 00:17:36,480 Speaker 1: that's generated and there goes down again and you have 296 00:17:36,520 --> 00:17:38,879 Speaker 1: to build it back up by more jackhammering. But eventually 297 00:17:39,160 --> 00:17:42,240 Speaker 1: these larger cracks that you're making come together and then 298 00:17:42,320 --> 00:17:45,480 Speaker 1: big chunks break off. And then when a big chunk 299 00:17:45,560 --> 00:17:48,160 Speaker 1: breaks off, you want somebody to come in and clear 300 00:17:48,160 --> 00:17:51,160 Speaker 1: the chunks away while you move the jackhammer, because you're 301 00:17:51,160 --> 00:17:53,320 Speaker 1: just gonna be breaking up those chunks. And that's not 302 00:17:53,359 --> 00:17:55,840 Speaker 1: the point of jackhammer anymore. Now. The point is you're 303 00:17:55,840 --> 00:18:00,400 Speaker 1: trying to remove whatever material in his bigger pieces can 304 00:18:00,440 --> 00:18:04,520 Speaker 1: be removed, you know, like by like a bacco with 305 00:18:04,560 --> 00:18:07,480 Speaker 1: a bucket or something. Um. Obviously it can't be too 306 00:18:07,480 --> 00:18:08,840 Speaker 1: big because you might have to break up in the 307 00:18:08,920 --> 00:18:12,040 Speaker 1: smaller bits. But you don't want a three million little 308 00:18:12,080 --> 00:18:13,719 Speaker 1: tiny rocks at the end of it, right, you're not 309 00:18:13,760 --> 00:18:19,600 Speaker 1: breaking it into gravel. No. The machines that do that, um, 310 00:18:19,640 --> 00:18:21,960 Speaker 1: some of these things actually uh, when when you create 311 00:18:22,000 --> 00:18:24,680 Speaker 1: a crater, that's good, but you don't want your crater 312 00:18:24,840 --> 00:18:28,560 Speaker 1: full of junk. So some of them actually have air 313 00:18:28,640 --> 00:18:31,440 Speaker 1: or water that blasts the stuff clear as you're going, 314 00:18:32,080 --> 00:18:34,680 Speaker 1: which is pretty neat too. Yeah, which is a it's 315 00:18:34,680 --> 00:18:38,440 Speaker 1: a big that's an issue because the stuff that that 316 00:18:38,560 --> 00:18:42,880 Speaker 1: dust that accumulates, that forms what's called the crushed zone, 317 00:18:42,960 --> 00:18:48,120 Speaker 1: that powder that distributes the force um is actually can 318 00:18:48,160 --> 00:18:50,320 Speaker 1: be a health hazard. And there's actually a lot of 319 00:18:50,320 --> 00:18:54,000 Speaker 1: health hazards with jackhammers. Uh. And we'll talk about them 320 00:18:54,080 --> 00:19:19,120 Speaker 1: right after this, all right, Josh, health hazards of jackhammering. Um, 321 00:19:19,320 --> 00:19:22,080 Speaker 1: that dust is no joke. Well, before we go to 322 00:19:22,119 --> 00:19:25,199 Speaker 1: health hazards, let me say this. What you and actually 323 00:19:25,200 --> 00:19:27,280 Speaker 1: can be a health hazard. It can be dangerous when 324 00:19:27,280 --> 00:19:30,920 Speaker 1: you get your bit stuck. Um. And the general rule 325 00:19:30,960 --> 00:19:32,920 Speaker 1: of thumb is you don't want to put the bit 326 00:19:34,000 --> 00:19:36,480 Speaker 1: farther down. You don't want to keep going down farther 327 00:19:36,600 --> 00:19:38,919 Speaker 1: than the length of the bit, because if you get 328 00:19:38,960 --> 00:19:42,480 Speaker 1: your bit stuck, then it's really tough to get back out. Yeah. 329 00:19:42,560 --> 00:19:44,760 Speaker 1: And while it may give you a little break, your 330 00:19:44,760 --> 00:19:47,320 Speaker 1: boss isn't gonna be happy, or if you're renting that 331 00:19:47,320 --> 00:19:49,400 Speaker 1: thing by the hour at your house, you're not gonna 332 00:19:49,440 --> 00:19:51,879 Speaker 1: be happy. Yeah, because you just used all of the 333 00:19:51,920 --> 00:19:55,439 Speaker 1: force of that compressed air to jam that that chisel 334 00:19:55,480 --> 00:20:01,080 Speaker 1: bit several inches into concrete. Yes, it's you need like 335 00:20:01,200 --> 00:20:03,479 Speaker 1: King Arthur to get that out. Yea, So moving around 336 00:20:03,720 --> 00:20:06,440 Speaker 1: um inches at a time, so it doesn't go straight 337 00:20:06,440 --> 00:20:08,640 Speaker 1: down into one spot. And you want a sharp bit 338 00:20:08,720 --> 00:20:11,639 Speaker 1: as well. Obviously a dull bit is gonna get stuck 339 00:20:11,640 --> 00:20:13,640 Speaker 1: easier and it's not going to break up the material 340 00:20:13,680 --> 00:20:18,000 Speaker 1: as well, exactly. Um. And like you said at the 341 00:20:18,040 --> 00:20:22,120 Speaker 1: beginning that jackhammers one of the noisiest tools around. It's 342 00:20:22,160 --> 00:20:25,760 Speaker 1: the worst. It might be the noisiest tool. Jack hammers 343 00:20:25,920 --> 00:20:30,479 Speaker 1: um create a noise at about a hundred and thirty 344 00:20:30,520 --> 00:20:33,480 Speaker 1: decibels from what this article says. Yeah, that is the 345 00:20:34,200 --> 00:20:37,000 Speaker 1: that is the sound of a jet engine taking off. 346 00:20:38,280 --> 00:20:41,560 Speaker 1: That's how that's how loud those things are and driving here, 347 00:20:41,800 --> 00:20:45,280 Speaker 1: no joke. I passed the dude using a jack camera 348 00:20:46,080 --> 00:20:48,359 Speaker 1: and he wasn't wearing ear protection. You know. I was 349 00:20:48,359 --> 00:20:50,359 Speaker 1: just about to say, is I bet you've never seen 350 00:20:50,760 --> 00:20:55,240 Speaker 1: a jackhammer operator not use ear protection? I never have 351 00:20:55,400 --> 00:20:58,160 Speaker 1: until today. That's nuts. Isn't that a weird coincidence? Though? 352 00:20:58,280 --> 00:21:01,879 Speaker 1: It is totally weird and like just dumb. He's like screwed. 353 00:21:01,960 --> 00:21:07,080 Speaker 1: I got health insurance. Uh, construction headphones are a must. Um. 354 00:21:07,119 --> 00:21:09,280 Speaker 1: And because we're talking about how how much it wears 355 00:21:09,320 --> 00:21:12,600 Speaker 1: you out. If you're on a road crew, Um, you're 356 00:21:12,640 --> 00:21:17,160 Speaker 1: probably gonna be rotating out jackhammer duty. It's not like Chuck, 357 00:21:17,240 --> 00:21:20,040 Speaker 1: You're on the jackhammer for ten hours today for the 358 00:21:20,080 --> 00:21:22,600 Speaker 1: rest of your life. Yeah. Yeah, And it's a it's 359 00:21:22,600 --> 00:21:28,320 Speaker 1: a real thing. Like people who use jackhammers as their profession, 360 00:21:28,960 --> 00:21:31,560 Speaker 1: they do face a lot of problems. That dust is 361 00:21:31,760 --> 00:21:35,040 Speaker 1: you know already mentioned that, but concrete has a silica 362 00:21:35,080 --> 00:21:37,960 Speaker 1: and that's been proven to cause lung cancer, and so 363 00:21:38,119 --> 00:21:41,080 Speaker 1: a lot of these jackhammers will have a like a 364 00:21:41,080 --> 00:21:44,240 Speaker 1: water sprayer at the end of them that just constantly 365 00:21:44,320 --> 00:21:46,879 Speaker 1: is introducing water that keeps the dust on the ground 366 00:21:46,920 --> 00:21:49,760 Speaker 1: and like a puddle. All right, And what's the different 367 00:21:50,119 --> 00:21:52,200 Speaker 1: or the deal with this. I know you didn't get 368 00:21:52,200 --> 00:21:54,280 Speaker 1: a chance to look at it, but you sent a 369 00:21:54,320 --> 00:21:58,439 Speaker 1: pretty interesting thing on the negative effects of vibration on 370 00:21:58,480 --> 00:22:01,359 Speaker 1: the human body. Yeah, it's weird. What's the deal there? 371 00:22:01,520 --> 00:22:04,679 Speaker 1: So vibrations are very odd. They used to belong in 372 00:22:04,720 --> 00:22:08,960 Speaker 1: the realm of Eastern Europe behind the Iron Curtain. They 373 00:22:09,000 --> 00:22:12,000 Speaker 1: did a lot of research in the effects of vibration 374 00:22:12,119 --> 00:22:15,560 Speaker 1: on the body and it does everything from cause insomnia 375 00:22:16,080 --> 00:22:20,760 Speaker 1: to digestive issues to motion sickness. And this is bad vibration. 376 00:22:20,800 --> 00:22:23,560 Speaker 1: I mean there's also like good vibrations. There's also good, good, 377 00:22:23,640 --> 00:22:29,520 Speaker 1: good vibrations. There's there's vibrations that that that that vibrated 378 00:22:29,560 --> 00:22:32,600 Speaker 1: a certain frequency certain hurts and I don't remember what 379 00:22:32,640 --> 00:22:34,879 Speaker 1: it is, but it's like a low it's like a 380 00:22:34,880 --> 00:22:39,840 Speaker 1: low frequency vibration. And there's there's something called whole whole 381 00:22:39,880 --> 00:22:44,159 Speaker 1: body vibration which UM. Apparently GM is dealing with the 382 00:22:44,240 --> 00:22:49,400 Speaker 1: problem right now. They have like their their largest UM. 383 00:22:49,720 --> 00:22:53,119 Speaker 1: I guess maybe they're tahoe or something, but they're large SUVs. 384 00:22:53,600 --> 00:22:57,600 Speaker 1: They had to really strengthen the cage so that if 385 00:22:57,600 --> 00:23:00,560 Speaker 1: it rolled over, it wouldn't crush the the bottom of 386 00:23:00,600 --> 00:23:03,679 Speaker 1: the truck wouldn't crush the roof. But the thing is 387 00:23:03,720 --> 00:23:07,000 Speaker 1: so rigid that when it goes at like highway speeds, 388 00:23:07,119 --> 00:23:10,200 Speaker 1: it vibrates that this this frequency that's perfect and it's 389 00:23:10,240 --> 00:23:13,800 Speaker 1: giving the driver's motion sickness. So yeah, there's all this 390 00:23:13,960 --> 00:23:18,000 Speaker 1: weird stuff that happens from vibrations and exposure to vibrations, 391 00:23:18,080 --> 00:23:21,359 Speaker 1: and so that's whole body. There's also hand arm vibration 392 00:23:22,040 --> 00:23:26,760 Speaker 1: and um there's something called rayn nodes phenomenon and it's 393 00:23:26,760 --> 00:23:32,040 Speaker 1: basically like your hands being exposed to vibrations for that 394 00:23:32,080 --> 00:23:34,160 Speaker 1: many hours out of a day. And this can happen 395 00:23:34,200 --> 00:23:36,359 Speaker 1: too if you're if you're working with like a gas 396 00:23:36,359 --> 00:23:39,439 Speaker 1: powered weed whacker all the time, or but especially if 397 00:23:39,520 --> 00:23:43,600 Speaker 1: jackhammer operators going to run into this, this circulation gets 398 00:23:43,600 --> 00:23:47,080 Speaker 1: basically cut off from all the the exposure vibration in 399 00:23:47,119 --> 00:23:49,479 Speaker 1: your fingers and it can get so bad, especially when 400 00:23:49,480 --> 00:23:51,840 Speaker 1: it's cold out, that they just turn white. It's called blanching. 401 00:23:52,280 --> 00:23:55,440 Speaker 1: They loosensation. If you're lucky, if you're not lucky, there's 402 00:23:55,480 --> 00:23:57,920 Speaker 1: a tremendous amount of pain in them. You can't grip things. 403 00:23:58,240 --> 00:24:01,360 Speaker 1: And if you're a jackhammer operator, that's a big problem 404 00:24:01,359 --> 00:24:04,240 Speaker 1: because you need to be able to grip the jackhammer. Yeah. 405 00:24:04,359 --> 00:24:07,960 Speaker 1: And um, I mean weird psychological issues brought on from 406 00:24:07,960 --> 00:24:12,440 Speaker 1: like fatigue and that constant noise, headaches in the insomnia 407 00:24:12,520 --> 00:24:14,359 Speaker 1: that can all lead to you know, you're kind of 408 00:24:14,400 --> 00:24:17,280 Speaker 1: losing it a little bit. Uh. Yeah, you never really 409 00:24:17,280 --> 00:24:19,320 Speaker 1: thought about that, all of it put together. It's called 410 00:24:19,440 --> 00:24:22,359 Speaker 1: vibration sickness. And we're only now just starting to like 411 00:24:22,440 --> 00:24:28,680 Speaker 1: really understand it. Uh. Shrapnel is also a danger, of course. Um. 412 00:24:28,720 --> 00:24:30,280 Speaker 1: And and these are you know, if you're on a 413 00:24:30,280 --> 00:24:33,719 Speaker 1: construction site, you know all this stuff. But since you 414 00:24:33,760 --> 00:24:37,200 Speaker 1: can go out and rent a full fledged jackhammer because 415 00:24:37,240 --> 00:24:39,320 Speaker 1: you want to take out your driveway this weekend, I 416 00:24:39,320 --> 00:24:41,040 Speaker 1: think a lot of people go into it lightly. Like 417 00:24:41,200 --> 00:24:43,920 Speaker 1: I've seen those things on the road. I can do that, 418 00:24:44,840 --> 00:24:47,920 Speaker 1: be careful, like don't do it and flip flops or 419 00:24:48,040 --> 00:24:52,359 Speaker 1: tennis shoes. You know, get get your big heavy hobnail boot. 420 00:24:53,359 --> 00:24:56,960 Speaker 1: It's the great Larry Munson said, put those on. Get 421 00:24:57,040 --> 00:25:01,240 Speaker 1: your ear protection where I protection, wear long pants and 422 00:25:01,720 --> 00:25:04,360 Speaker 1: you know, don't be a dummy. It all seems like 423 00:25:04,880 --> 00:25:07,719 Speaker 1: basic safety issues. But yeah, I bet you there's been 424 00:25:07,720 --> 00:25:12,000 Speaker 1: a dude with short pants and a flip flops they 425 00:25:12,119 --> 00:25:17,120 Speaker 1: tried to jackhammer something. Jack hammeron right there is it'll happen. Oh. 426 00:25:17,200 --> 00:25:20,960 Speaker 1: They also important thing too. If you're doing this at home, um, 427 00:25:21,000 --> 00:25:24,240 Speaker 1: and you don't like your sidewalk um that leads to 428 00:25:24,280 --> 00:25:28,280 Speaker 1: your house, get the electrical and gas companies out there. 429 00:25:29,000 --> 00:25:30,800 Speaker 1: And I don't even think they charged for it, or 430 00:25:30,880 --> 00:25:32,840 Speaker 1: they might, but they'll they'll come out there with a 431 00:25:32,840 --> 00:25:35,040 Speaker 1: little spray can and they will show you and draw 432 00:25:35,320 --> 00:25:37,560 Speaker 1: paint on the ground where your gas lines and your 433 00:25:37,600 --> 00:25:39,840 Speaker 1: power lines are. Because you do not want to jack 434 00:25:39,880 --> 00:25:44,000 Speaker 1: cameront either of those not fun. Be careful, don't be 435 00:25:44,040 --> 00:25:49,159 Speaker 1: a dummy. Well that's ours a huh. Jack hammers the 436 00:25:49,200 --> 00:25:51,920 Speaker 1: most interesting tool on the on the planet. Oh. I 437 00:25:51,920 --> 00:25:55,159 Speaker 1: actually got one more thing, believe it or not. What uh? 438 00:25:55,200 --> 00:25:59,679 Speaker 1: In two thousand because these things are so loud, you know, Uh, 439 00:25:59,720 --> 00:26:04,480 Speaker 1: the Department of Energies Brookhaven National Laboratory released a helium 440 00:26:04,640 --> 00:26:08,760 Speaker 1: jack camera called the Raptor, and it had some of 441 00:26:08,760 --> 00:26:11,600 Speaker 1: these things come with rubber boots to try and soften 442 00:26:11,840 --> 00:26:14,240 Speaker 1: the noise, but I don't think they do a great job. 443 00:26:14,880 --> 00:26:16,840 Speaker 1: Um this thing actually less than the noise to eighty 444 00:26:16,840 --> 00:26:20,200 Speaker 1: seven decibels. That's like nothing, nothing, that's like how loud 445 00:26:20,200 --> 00:26:24,159 Speaker 1: I'm talking right now. But apparently it never like caught on. 446 00:26:24,840 --> 00:26:27,639 Speaker 1: Then in two thousand eleven, another equipment maker had an 447 00:26:27,640 --> 00:26:31,920 Speaker 1: electric model that said it's faster than Newmatic and it's 448 00:26:31,960 --> 00:26:34,400 Speaker 1: only a hundred decibles and they have sold a few. 449 00:26:34,440 --> 00:26:37,760 Speaker 1: But apparently, like breaking into the construction industry with a 450 00:26:37,840 --> 00:26:41,040 Speaker 1: new type of tool is super hard to do. I 451 00:26:41,080 --> 00:26:44,480 Speaker 1: think in New York especially, they were very resistant. The 452 00:26:44,640 --> 00:26:47,000 Speaker 1: unions were like, really won't work, We're not using those. 453 00:26:47,680 --> 00:26:50,600 Speaker 1: That seems like where they should do it, because um 454 00:26:50,640 --> 00:26:55,240 Speaker 1: I looked it up. Apparently six of noise complaints and 455 00:26:55,720 --> 00:27:01,399 Speaker 1: from in New York City we're Jackhammers. That's almost thirty 456 00:27:01,400 --> 00:27:05,840 Speaker 1: four thousand complaints in a year, Jack Camering, New York 457 00:27:06,920 --> 00:27:09,879 Speaker 1: and supposally you're not supposed to do it after six 458 00:27:10,000 --> 00:27:13,320 Speaker 1: or before seven am, but there they allow it in 459 00:27:13,400 --> 00:27:15,879 Speaker 1: certain cases. And I feel like that is like, is 460 00:27:16,080 --> 00:27:18,840 Speaker 1: all the case is chuck in a hotel nearby? Then 461 00:27:18,920 --> 00:27:23,720 Speaker 1: do it started five that's all I got. Uh. If 462 00:27:23,760 --> 00:27:25,680 Speaker 1: you want to know more about Jack Cameras, you can 463 00:27:25,720 --> 00:27:28,199 Speaker 1: type that one word into the search bar at how 464 00:27:28,240 --> 00:27:30,960 Speaker 1: stuff works dot com. And since I said Jack Camera, 465 00:27:31,000 --> 00:27:35,879 Speaker 1: it's time for listener Now, I'm gonna call this cool 466 00:27:36,119 --> 00:27:39,400 Speaker 1: program for kids in Austin, Texas. Oh yeah, I hope 467 00:27:39,400 --> 00:27:40,879 Speaker 1: you guys are doing well. I've been listening to the 468 00:27:40,920 --> 00:27:43,840 Speaker 1: show for for some time. Like to thank you for 469 00:27:43,920 --> 00:27:48,199 Speaker 1: giving me the edge on many debates and discussions. I 470 00:27:48,280 --> 00:27:50,040 Speaker 1: live in Austin, Texas and I'm writing today let you 471 00:27:50,080 --> 00:27:52,680 Speaker 1: know about a program I recently started working for, but 472 00:27:52,720 --> 00:27:55,880 Speaker 1: I think you'll appreciate. It's called a Totally Cool, Totally 473 00:27:56,000 --> 00:27:58,880 Speaker 1: Art t C t A. It is a free after 474 00:27:58,960 --> 00:28:03,360 Speaker 1: school program does to reach out to us youth and 475 00:28:03,440 --> 00:28:05,920 Speaker 1: give them some exposure to the arts. The class I 476 00:28:06,000 --> 00:28:09,399 Speaker 1: teach is called the Art of Machines, and we build 477 00:28:09,520 --> 00:28:13,360 Speaker 1: various contraptions. We have sent you an example project, which 478 00:28:13,359 --> 00:28:16,760 Speaker 1: we call bugs that the students building our class. Did 479 00:28:16,760 --> 00:28:19,000 Speaker 1: we get this in yet? I don't think all right, 480 00:28:19,000 --> 00:28:22,080 Speaker 1: I don't think i've seen this Brian so he sent it? 481 00:28:22,040 --> 00:28:26,080 Speaker 1: Awhile ago, Oh he did? If you did, I don't 482 00:28:26,080 --> 00:28:28,960 Speaker 1: know if we got it. No, we haven't got in yet. 483 00:28:29,200 --> 00:28:32,199 Speaker 1: All right, So if it's recent Brian, then it's on 484 00:28:32,240 --> 00:28:35,119 Speaker 1: the way. If not, then send it again. That was 485 00:28:35,160 --> 00:28:37,359 Speaker 1: one of a kind. Uh see what you think about 486 00:28:37,480 --> 00:28:40,880 Speaker 1: is the prototype? I hope not.
