Gentlemen, welcome back to the shop. Scooch on over there. Plenty of room around our fire for everybody. If and you're the type, look at this ancient Unearthed Arcana attested tool.

What we got for ten doll hairs. What possibly could it be? Now as I said, plenty of room around our fire. Thanks for sharing a turtle and a chuckle in the shop and you're the type of fella comes into a guy's shop in order to take a in the corner and complain about the smell. Don't be surprised if you get called.

We got the finest brainiacist comment section tongue tangulated there on all of Tinternet, so we intend to keep it that way. We're gonna have a part at this modernly. it's one of these things: Reciprocating pecker puncher budect in beautiful aluminum. This is an early version, quite over built of a Sawzall it's a recipro saw look at that.

You can put a handle in there if you're of the left hand path. bent his Sinister handed. you got threaded holes in the other side. We're gonna find out what type of plastique is in here I would guess abs with no glass fiber reinforcing.

We will soon find out. Feels like one of the mold rotary phones. The foot mounting is quite quite a slotted head screw and a square Carriage nut. Oh, it's even got a split washer.

Mayhap predates recycling marks. See anything on there, but it's got that Sheen of abs. and I need a knife? There is no grind of entrained glass fiber. so that's straight abs.

No smell at all to her. You can see how polished the mold was here. Shiny, shiny. The big beefy old school lazy motor.

3.8 amps for red. correct 3.8 amps inch and a quarter stroke. It reminds me of my buddy, the Dew Claw. you got a needle dick you gotta like a sewing machine.

Design is interesting. They didn't optimize for using plastic parts. All of these are die cast aluminum frames around the motor and then those get bolted into the plastique. You would not see that nowadays.

Normally the motor bearing is right in the housing. The plastic housing comes from a bygone age when Grease was cheap. You see it wasn't well used to. Still quite pristine as witnessed as well by the reciprocating Dingle arm not having any kind of wear on it at all.

The way this works are angry Pixies dancing around to and fro from the wall and which fires through a triac. Now the triac. You can adjust how much on the to it. How do you explain that? It's a kind of diode that chops off part of the waveform.

The AC waveform depending on what position the potentiometer on this slider is at. So you get more or less voltage going to the motor, goes through the brushes, into the commutator of the motor, these copper bars and then in through the windings and gets the thing to spin. We have a tiny little pinion and a monstrous big bull gear. This mechanism is the reverse of an infernal combustion engine, whereas you would have an explosion on the Piston end which would drive this back and and force this to turn.

What we have is an electric motor turning this bull gear and if you can see in there there, there's the oh we're getting fetched up on the brushes. sorry instead of being a wrist pin like on a engine, what we have is a sliding Channel and a pin goes up and down in the sliding. Channel One thing that's interesting about this mechanism is that with the wrist pin on the down stroke at the at the changeover point, you have the least amount of torque happening. But this is exactly the opposite because it's on a slider.

as it comes through. this will develop more and more torque through top dead center and bottom dead center. So this is a very interesting mechanism so that you don't get stalled out on the bottom of the stroke. you actually have more torque, more available torque at the top dead center and the bottom dead center loosened off the bearing housing.

For the gear set, you see the bull gear has a hardened Bush on a pin or rides in this slot here. It's a very tight mechanism, good fitment and if I had to guess I would say hardened. But I don't have to guess because somewhere in this pile we have a file. This is going to guide you down here a little bit.

You'll have to trust me on this one. You listen to that foreign Spike through Jesus foot they didn't have OSHA approved. Jerusalem Jordans Back then, it's plainly evidenced by the parts splayed out before you. This thing is skukamera's free! I Love the way they built this all metal injection.

It essentially spared no expense. This would have been a super expensive tool at the time, you know. I only paid but 10 bucks, but it was Helen As evidenced by the fact it appears to still be working. There's nothing to really go wrong.

Maybe the triac would crap out in here. You wear out the brushes. This doesn't seem to have seen much use but hardened parts. All this machined.

die casting. nice die casting too. Real deep draws the motor. The motors got insulators on it so this is a double insulated tool despite having all this metal so you have to electrically isolate the motor from the housing and the housing.

Being aluminum, that's a little bit tough to do, but they got fiberglass rods through here with some bake, a lighter hydrometer, rubbery type stuff. You just don't get a tool like that nowadays. they're more optimized for, well, profit. Is that a good thing or a bad thing? Well, I'll have you note that Simpson Sears no longer exists.

so that's the thing Anybody can build a bridge to last a thousand years, but it takes a special kind of engineer to lost a bridge to just barely survives. Part Near put back together. she's chooching. Yeah, spin them a thing.

in any way, it occurs to me we don't need to put the clamshell back on on account of this housing containing all the bearings in the motor and so forth. It shocks people to no end to find. I'm not an electrician I Don't like being shocked I'm going to put my safety nitrile gloves on and then we'll actuate this and be able to see it. Okay, let's plug her in.

Uh, foreign Mount Nice and beefy and Universal got a nice little pin in there. We got our hard Oak here. We'll give her a try. It doesn't have a whole lot of power, let's just have a look with the kilowatt, how many amps were drawn power and Watts we could just do the calculation, but we'll let the machine do that for us.

Foreign. not stalling out at the end of stroke. We're just going to test that. I got her jammed right proper in a tooth and well.

I Don't think a modern Sawzall does that. There's a modern saw. It's all jammed right in there like a polar bear. swim.

We'll come on to it. Ah, full of happens. Look at this thing. They do not build them like that anymore.

considerably lighter and it's modern counterparts. Surprisingly, despite this being the compact version, still heavier than the old guy and all this aluminum. I mean pretty beautiful. You can't buy a tool like that anymore.

Ergonomics are hokey but and doesn't have near enough power. It's it's got enough to to cut through some wood, but not nearly as much power as it's modern day equivalent. So thanks for watching Get your dick in a vice. But wait, there's more world's crappiest Die Filer let me just move this open hydraulic pump I Tried.
