You walk into the Pakistan Josh Clark, Charles of each of bright and Jerry's over there, which means time for study, should now Jack hammer this common asset. That's right! the most annoying one of the most annoying sounds. I know you did the wheat flour here I think the leader camera there sure with we now live in Europe? If we lived in New York, Jackhammer be number one. I feel like it state in a hotel in New York, where there was in a general way below me, no one even a chance. Every single time leave flow It's a lot more frequent down here and in Atlanta their jackhammer loudly flows in York, city

now about leaves more or less than a search. Your none can somebody are there so we don't usually shouted. Thank you at the beginning of an episode, but we got a couple of gifts that are so special. We wanted really so Peter O Donnell and the gang had built sharp knives b. I tell tee sharp at a Philly sent us sent me a chefs life. You sent you a Felina beautiful and it's one of the most gorgeous pieces of like handmade craftsmanship. I've ever seen yeah, it's amazing. I cannot wait to catch fish. How did I get wait for that? For your Cathay thing, open factors that are really you can lock the had offered so alive? Now you're supposed to be with a hammer. Some people do. I do now.

But these things are gorgeous. I mean the blade itself. I mean they hand make these the handle the wait. It's just it's a piece of art, and not only that it is the sharpest thing I've seen in my life, I know it's like dangerous. Marijuana yell danger their knives. There are supposed to be sharp debt but add wielded with respect per year, while the respectable, not fear that you can actually going to Tumblr. Can just search hashtag knives. You should know around word and it is a chronic goals in pictures. In short, captions, a brief captains that the process of making our knives is off

she's really need. I just love like hand crafting in forging steel like those lost arts right in a lot of ways and now they're doing it right. Man, there really beautiful comin anyway. Thank you print Dalia. Thank you guys. Yeah thanks be. I was really cool, so Jack amorous here Jack Hammer, if they were sharp, is built short knives. They beyond somethin northward work quite the same value. Not so yes, it's true. We are actually talking about jackhammers and yes, it's true that jackhammers are about what you think they are, but there also current interesting when you certainly look into my area or yes, who think about, I didn't realize this article pointed out a jack hammer. A hammer and a chisel. That's right, but it hard core hammering sizzle year, and it takes out of the equation, largely the human, whose back in shoulder muscles, have to be involved in every single strike.

That hammering sizzle you're talking John Henry in the sledge hammer. Yes exactly there, because prior to the advent of the jackhammer mount the eighteen. Forty eight to fifty by the turn of the last century. We had jackhammers, came down Pat, it was the sledge hammers, and pick axes to remove rock. There was a real deal of. There was like it killed. People like it literally could kill you what kind of work yeah I mean mining is still very dangerous job but Industrial revolution mining was no fun dangerous deadly and even if you didn't die, it's just brutal, brutal back baking work, making work, singing a sledge hammer gap, you ever slung sledge sure it's the worst. It's it's hard work. You ever used jackhammer, no

it's awful. Well, that's the thing: it's it's better than the sledge hammer AIR, while in some ways, but its brutally difficult, This is probably one of the most brutal tools you can use honour, any kind of sight, yeah and for any kind of project. There are there many that's it I'm gonna, take as much out of you knows the jackhammer, it's tough on your body because they way hundred pounds like a normal heavy duty. Jack hamburger weighs about a hundred pounds, yet the hold it in place up right there I'm gonna jump and around or those probably not going to anyway. It's it's designed not to jump around right, but you still do you want? I can keep it enough, We can find area which means you're, using your muscle to study it yeah, while it's going up and down at a very, very fast rate, some of those things- with the ground, one thousand and forty five hundred times a minute, yeah yeah, it's tough, it's the only to that end.

The hardwood floor skimmer. You know like that, the orbital inertia. You can use that, unlike what assailing Pat on the hardwood floor and that thing in sledge hammer, the only some of these tools that I felt like work controlling me, not me not controlling the tool. I guess it until you get at once. You get it. It's a little better, but at first when he first start usage, you can run a jackhammer sea area of Europe. That's your driveway! You can go! Do it yourself if you hear a fool I am sure that you don't need the driveway anymore before you do they're here, but Once you get the hang of it, you can. I can wield little bit, but it's tough. I mean it it'll, be it feels like. I have no power of control over the same right. I can imagine so it is a very difficult tool. But again the alternative is early death and the other alternative, which is to call someone did

for you is the best option of the three but say that you are king, Carlo, Albert Sardinia and the years about eighteen, thirty, something! Eighteen! Forty and you weren't a train tunnel built through a mountain and the tunnels. Gonna need to be twelve kilometers long. You do call somebody else put that somebody else you cargoes are now at the time you buddy we could try, pickaxes or whatever, but you're. Not so can we allow by the time we finish there? What can we do? Actually, this call for twelve kilometre long tunnel through a mountain in Sardinia, prompted the de the early forays into developing pneumatic tools like a jack hammer in eighteen. Forty, eight getting Jonathan Couch built a what he called a percussion drill, and this had a bit that was, it went through the piston of a steam engine.

Distant driven bright. Then contemporary Joseph FAO actually attached to the pistol, and then he started in eighteen when using air which is pneumatic right to power, it yeah, but these were still attached to a piss. And it wasn't until eighteen. Eighty five with Charles raided king, when he actually is given credit for inventing the the traditional looking and held modern jack. Modern, pneumatic powered jackhammer right and he gets a lot of credit for stuff. It was already built, like They will say he was actually the inventor of the automobile. Now he was it, It was the inventor the ghastly powered automobile. No, it wasn't here is the first guy in Detroit, build and driving around here any did end up Inspiring mentoring, ransom old and Henry Ford and some other early car manufacturers here and is almost single handedly responsible for making Detroit Motor City the at risk.

By also Stanley right through the eighth freely. I like that, guy stuff, when you meet, didn't get kicked out a kiss. I think he was sorted, not invited back here. I think it's a money move there will have to pay. The name was sir other guitar player nearly his bill. He was a founder of the band right now. How do you get kicked out like that for money? I think you pass damaging summons. Probably own gets incorporated anyway. I'm John did Charles Brady saying he put Detroit on the map as far as auto manufacture go and he did do a lot of refining of pneumatic tools, including the jackhammer any does hold. The Patrie did hold the patent for again. He ended a lot of stuff. He was a sharp guy and though the pneumatic, the factors pneumatic, which means aired, powered compressed air powered,

is the reason why most jackhammers today are still compressed air powered it's because of the mining application yeah like when you mine, you really seeing a lot of potentially explosive gases and you can't have something like a steam engine. It combustion power down there yet or you can't have an engine in their releasing exhaust, and you can't have a jackhammer that will spark a rock while that may happen, no matter what right one I'm saying you can't have that among volatile gases right. So you air, driven, is the perfect the key, because you dead matter at that hoses a thousand feet long, yeah you're, not gonna, lose power. You can convey rest yet hear me compressed air up against him stare and upon the surface you get a diesel engine that powering piston just like in your car and the pistol moves up.

The cylinder as moves down, it can presses the air the cylinder and places it down into a storage tank where it sits, compressed air and thus released out. The and through the hose, and it ends up another Cameron, yet, no matter how far away it is still going to be just as powerful and that compressed air is final. I'll, you can be a happy minor, also live long day. Will you buddy you're good excited to. That means we need to take a break in, but the spill on your tongue- and I will come back right after this New year's resolutions are very, very difficult to keep getting exercise save more money. What about this? We have a resolution that you can really work with stop wasting time going to the post office that right you stamps dot com instead because they bring all the services of the Eu S postal service right to your computer, with your small business, sinning invoices,

or packages or an online seller shipping out products stamps that can handle it all with ease yank it. This was simply come. You get five cents off every first class stamp in up to forty percent of priority mail. This right? U S, postage twenty four, seven for any letter, any package, any class anywhere you want to send it! There's no risk and using our promo code, ass white, ass, gay you're gonna get this offer afore weak trial, plus free postage and a digital scale, and there are no long term commitments or contracts just go to stamp that come click on the microphone off the top of the home page and type in s. Why, as K that stance, I come promo code S, why S K stamps outcome or go to the post office again.

I feel now. Relax affected I love the title of this next section: air power, destruction NEA can't get an electric jackhammer. If you ve ever gone to a hardware store, they have he's kind of smaller handheld jackhammers that you can take up like your bed. Four tile, pretty well with it plug it into the wall, has little chisel. On the end of it, but that's small beans. He can't do a driver no way or concrete or asphalt with was something like twelve kilometer tunnel through mountains heard any now. You need the big T shaped Jack hammer and here's one of the things I recur to me. One of the reasons

So well is because a so heavy right it's now. I think they will, let's make missing wave fifteen pounds or twenty pounds to make it easier to Rhine. Missy probably could yeah- maybe could do that today- would jump all over the place. You want nothing super super heavy because that's part of the power and force behind a threat, so he sees a numeric right. Just like on the compressed air compressor upon surface when you down in the mine, they actually have jackhammer has a pistol in a prison in a cylinder and right, and it's exactly really kind of simple. When you cut the thing open and draw a cross section of it, which we did their hands after could shoot you you, you can see that really the whole mechanism comes down to a trigger valve right, that's right! So what you have you got the pressure chamber

compressor enters that chamber activates trigger valve, and it is because of the compressed air opens and shuts really fast right into the trigger valve moves. The air, either above the piston or when it closes in the air, goes down below the piston, which means chisel goes up. Chisel goes down bright, kissed the pistol in striking the top of that chisel bit driving it downward. When the compressed air comes in and pushes the sit down and then when the the valve closes in the air goes underneath the pistol there's also spring in there. That brings the job it back up they would work very well. If you do not,

down where we had to go down and reset it, and apparently the earliest. The earliest jackhammer had that very design. That feature that was it like a pale and then you'd have filigree, said Dan and reset it, and there are like this isn't gonna work here that sort of like the the pneumatic guy cattle punch they that what's his face, used and no country, Romania, one way is exactly like that neighbouring get if you're trying to bust concrete but good. If you want to put a lie down, a cow and trade didn't stand them, it does the eternal stun. I think it stands a cow and then they kill him. I thought it. They put it into the brain to kill the girl. Now I dont think. Actually I think I can and probably does sometimes, but I think the main purpose of it is the stone the cow. So it's not like it's just days and out of it when it and when they

No, are you yea hydraulic jackhammers? It's the same. Jackhammer would kill a cow, hydraulics, use, fluid same principle bright but doesn't use air you ve ever seen yeah. They have jackhammers. You can there really large that you can't handle is a person, but it's like attached to a back over something right. That's for big big jobs! Another usually I draw a new matic right, but probably not every time. I'm sure someone, the construction industry will correct Well, I went and looked and if you go on our bother that you know that I has everything and they have hydraulic jackhammers, Foresail, what's Alabama

The next time all it's like China's Amazon, but they still very thing. I've. It's nothing! I came off and you think everything's like Skype. Let's go now become back as you do come, but they did seem like all of the back how attached jackhammer we're hydraulic that I saw ok, well, here's what happens if a thousand a forty five hundred hits per minute that chisel bit and if you're breaking up rock the different kinds of bits appointee bit. We reckon up like a dry where something is is really good or you can use a flat for other applications, so yeah, if you break into driveway in all, you want, is for the driveway to go by here yet appointed, the one you want. It's not a controlled cut right, the the like of Flathead screwdriver style bit, is the kind that where you can really kind control, where the cracking goes right,

if you wanna, like it said we were taken up your floor time. You had a handheld version rats what you want to disputed underneath yeah, the time chip. It up and there's actually there's like come some insane mathematicians have actually like trying to figure out how you can predict how cracks the gate. A really yeah, there's like are for the most efficient jack, hammering pretty much like what they all work best. If I were to place inherit how to use it, but I am one of the things I didn't understand before, is that When you are Jack, hammering you, you are creating different types of flaws, basically in the South say concrete structure and when you're doing that the first floor you're doing their first failure. Creating is this some kind of surface powder that the initial chips you're making, actually powder rising in in

congealing around the drill bit right right and that powder actually transmit the impact of the jackhammer throughout asked a very concrete pad and their immediate area there actually starts to create cracks. So you think well, it's just the drawback, creating crack. It gets in their enough You know it's it's generating like these different materials from the very concrete itself and its using those materials to distribute the force and create cracks that ultimately start to spread and propagate, and spread and propagate they get bigger and bigger than a chip comes off. The chip comes off the amount of force. Generated in there goes down. Again, and you have to build it back up by more jack, hammering buddy. Actually, these larger cracks that you're making come together in a big chunks break off yet and then, when a big jumper,

Are you why somebody to come in and clearly chunks away? Try you move the jackhammer, because you can be breaking up the chunks and that's not the point of jackhammer anymore. Now the point as you're trying to remove whatever Material in his big pieces, as can be removed, yeah right like by but like a bacco with a bucket or some pleasure ABC can be too big, as you might have to break up and smaller right. I dont want of three million little tiny rocks at the end of it. Throw you not break anew and gravel now that machine to do that. Some of these things actually would, when you create a crater, that's but you don't want your crater full of junk. So some of actually have

air water that blast the stuff clear as you're going with every need to which is it's a big, come at an issue because the stuff that that does that a cumulative that's forms with called the crushed his own, that powder that distributes the force there is actually can be a health hazard and is actually lot of health hazards with jackhammers, we'll talk about my after this here's, the thing save money with Geico was almost better than playing pick up basketball, because there's always that guy who joins your game He never passes the rock he constantly bricks theories and who completely you and then put his hands up and say no foul, no foul with Geico. It's easy to switch. Save on car insurance known-

the vacant ankle sprain, because you're absolutely exhausted. So which, in save with Geiger it's almost better than sport, I just health hazards subject. Every dust is no joke well before you to health hazards. Let me say this: what you then actually can be a health hazard can be dangerous when you get your bit stock and the general rule of thumb, as you don't want to put the bit. They're down you'd want to keep going down farther than the length of the bit, because if you get your bid stuck that's really tough to get back out, yeah and while it may be a little break, your boss in Vienna me happy or if your renting

by the hour at your house. You're not gonna, be happy here, because you just used all the forces that compressed air to Jim that the chisel several inches in new concrete. Yes, it's night, you need, like king, Arthur that yes, a moving around inches at a time. So it doesn't go straight down a new ones by an you, wanna sharp bit is well. Obviously, Adele Bit is gonna, get stuck easier and it's not gonna break up. The material is well exactly, unlike he said at the beginning that the jackhammers, when the noisiest tools round its the worst, it might be, the noises told jackhammers thumb, create a noise at about a hundred Thirty decibels from this article says here that is the that is the sound of a jet engine taking off that's how that allowed. Those things are.

And driving here no joke. I passed a dude using his camera, any wasn't wearing your protection, about to say is: I bet you ve, never seen a jack hammer operator not use your protection I never have until today, that's nuts and then a weird coincidence. It is totally weird and like just dumb, screw it. I get health insurance construction are a must. And because we are talking about how much it where's you out of your honor road crew, You're, probably gonna, be rotating out jackhammer duty, yes, not like Jackie on the jackhammer for ten hours today for the rest of your life, yeah yeah, that's it it's a real thing like people who use jackhammers as their profession. They do face a lot of problems that does this You know. I only mention that, but country has silica and it has been proven that cause lung cancer and so

of these jackhammers will have like a water sprayer. At the end of that is constantly is introducing water that yet dust on the ground in like a puddle? Are in? What's the difference the deal with this? I know you, I didn't get a chance to look at it, but you sent a pretty interesting thing on the negative facts of vibration on the human body gets weird. What's the deal there, so vibrations are very They used to belong in the realm of Eastern Europe, behind the iron they did a lot of research in the effects of vibration on the body. Bright Does everything from cause insomnia to digestive issues, to motion Sickness Elizabeth vibration? I mean there's also like good vibration, there's also good good good nurse, theirs, migration. Is there that the virus It is certain frequency certain her

and I don't remember what it is, but it's like a low figure, low frequency vibration and there's there's something called whole whole body, vibration, which apparently GM, is dealing with a problem right now they have like their their largest. I guess me they're Tahoe or something but their lot suvs. They had a really strengthen the cage that if a rolled over wooden crush the bottom of the truck wouldn't crush the roof, yes, The thing is so rigid there. Goes that like highway speed, vibrates at this, this frequency that's perfect in is giving the drivers motion sickness. Really so yeah, there's always weird stuff that happens from vibrations and exposure to vibration, vile and so that's. Whole body is also hand arm vibration and there's something called ray nodes phenomenon in its basically like you're hands being exposed

Relations for that many hours out of a day in this can happen to a few. If you're, working with like aghast we'd whacker, all the time re but especially jackhammer operators can run into the circulation gets basically cut off from all of us suppose rehydration in your fingers, and it can get so bad, especially once called did. They just turned white. It's called planting while they lose, station. If you're lucky, if you're not lucky, a tremendous amount of pain and I'm? U cant grip things, and if you're jackhammer operator that's a big problem, because you need to be able gripped the jackhammer yeah and let me weird psychological issues brought on from like fatigue next. That noise headaches and the insomnia that can Ali did can a losing it a little bit yeah yeah thought about the olive it put together is called vibrations. Some were only now just starting their like really understand it, a shrapnel is also a danger, of course,

These are you know if you're on a construction site, you know all the stuff, but since you can go out and read a full fledged jackhammer, because you wanna take out your way this week, you're right, I think a lot of people and threw it lightly. Like I've seen those things on the road I can do. That should be careful like don't do it and flip certain issues, man, you know, get get your big heavy. The hobnailed boot is the great Larry Munson said: put those on get your ear protection. Where I protection, where long pants in you know, don't be a dummy. It all seems like basic safety issues, but there are betcha. There's been a do, wouldn't short pants ended footlights it tried to jackhammers, somethin, take hammered right there, foot it'll happen, o the also an important thing to you. If you're doing this at home and you know what you're sidewalk. That leads to your house, yet the electrical and gas companies earlier

and everything they charge for it or they might but they'll go come out. There Spray Can- and I will show you and draw paint on the ground. We are gas lines in your power lines are yet you didn't. I wanna check Cameron either those not but be careful, don't be a dummy, lesser Pierre, say her here: Jack Hammers, the most interesting to know on the plan of action. I got one more thing, believe it or not what in two thousand, because he thinks you're so loud the department of energies. Brook the national laboratory released a helium jackhammer called the rapporteur, the rat, and it Some of these things come with rubber boots to try and soften the noise yeah, but I don't think you did a great job I'm missing actually lessen the noise to eighty seven decibels afflict nothing, nothing like hell out, I'm talking right now. But apparently had never like caught on. Didn't you

thousand Levin and other equipment maker had electric model. That said, it's faster the pneumatic and has only a hundred decibels than they had sold a few but apparently like breaking into the construction industry with a new type of tool is super. Do, I think in New York, especially they were very resistant, the youth very likely. They won't work when I use in those that seems like where they should do it, because I'm I looked it up. Apparently, sixty two percent of noise complaints and that from twenty fourteen twenty fifteen in New York City were jackhammers yeah. That's almost thirty! Four thousand complaints here jack? Yet more heat, net importer and supposedly units was to do it after six or or seven a m, but there they allow it in certain cases and feel like that is like this. All the case is in a hotel nearby of undue cited five. That's all you

If you want to know more about jackhammers, you can take the one word in the search bar house efforts that calm and incisive jackhammers simply listening Nicole, this cool programme for KIDS and Austin Texas because you're doing well been listening. Chauffeur for some time like to. Thank you giving me the edge on many debates and discussions. In taxes and arrange they. Let you know about a program I recently started working for. I think you appreciate the skull totally cool, totally art tcp eight. It is free after school programme designed to reach out to Utes youth and give them some exposure to the arts. The class- I teaches the art of machines and we build various contraptions. We have sent you an example project which we call bugs that students filled in our class. Did we get this? We're gonna think

You have seen us Brion said while ago we did. If you did, I don't know. If I got it, I don't know we haven't done so if its recent Brian than it's on the way, if not, then send it again there was one of a kind suit. You dig it out as the programme up. Not only is it my dogs go crate pretty things this is it. Twentieth anniversary. The programme returned, let people know about. So it can be around for another. Twenty years, we also have other classes, painting film fibre arts in photography. Anywhere else is hoping. Maybe you give a quick shot out for totally cool, totally art and Austin. It's so totally called anything What that up on Google or go to HTTP Ass Collins, LATCH, Lash, Austin, Texas, Don Giovanni Slash, TCP, snipers,

yeah there's from Brian FRY Jargon, good work, Clarion we're gonna be in Austin for South myself. What's this year, you do know through if we're gonna be selling tickets or if there is like history or what will find out. Let her go no, but I believe it's killing our deal.
