A

Actually fit through so if I can find them here. Most of these are marked.

A

They line up with two holes on this plate somewhere, that's right side up.

A

Ok, I haven't actually marked off there. We go right there. Now you would rotate.

A

And now and then of course you now- you bolt this down into that flange.

A

Otherwise it won't draw the tube through okay. So so we would put actually I'm not going to do it because we're not making these yeah.

B

So you've got to lock this down no.

A

You have to bolt this down yep, otherwise um it won't turn right so that so now you run- and this was made for 38.

A

Okay, that's what this is Louisville, okay, so you just put your 38 spike through here: uh-huh clamp, it up here and then just turn it on and you draw it through, and this is actually your holder you'll get a bend. You'll get a twist on it and it'll bend it and then it'll actually start pulling it around. Let's.

B

See where's the lung how's that work so you've got this I see. So it's winding to.

A

What it's doing is this calling the tube this way, how I you would stop, but.

B

A

There's a little more most hair pins are only just 180 degrees. These are a little more that's the way they did it. That's the way they made this one, so I actually had to come around a little farther. It's a little more difficult to do this, because then you get all this stuff in the way. Yeah.

B

A

You do this one down here. You have to kind of pry that apart so.

B

You feed it in you. Do you feed that you started half way about yet.

A

Here up, let's we'll make one real quick you tonight as well as long as you want to learn: okay there, there are other ways to clamp it as well, but you always need a top and a bottom plate to keep to keep it in this area. Ya.

B

Hear what I want you to do is stop it right here.

A

B

Stop it right here, let me just videotape one full revolution, so I could measure the amount of time it takes. Okay, so go ahead. Jo-Ann.

A

B

Now and this speed does not change no.

A

It's a constant speed and this.

B

Is for even up to 180 schedule, 180 scheduler.

A

160, yet that this is the six.

B

A

To wind everything so.

B

That's where you could.

A

Go you could you could go faster on some of the smaller stuff uh-huh, but it's you know why.

A

You want to be careful that you have to be careful and you have to be safe when you're doing stuff like this, because if you get easy to get injured.

B

A

B

We're coming up to here with that one so I.

A

Didn't look at the clock. You have a time yep.

B

I got a timer yep, so it was about about 50 seconds four.

A

B

Uh-Huh, would you like it you've got.

A

Your gear down in your box, but you also have the gear down between your two sprockets yeah, so that's like so like four to one or something on that yeah.

B

So basically, you like this speed, or would you go slower or faster? ah This.

A

Is a good: this is a good kid speed. Uh-Huh.

B

And tell me about this: so your hydraulic power unit here yep, so you've got what how many horse of a motor.

A

B

A

Yeah see out the hydraulic, fluid is also.

B

A raised everything.

A

It's just it's just something you can buy off the shelf. Mm-Hmm, don't even know if.

B

It's an electric, so this is like the power cube, except it's a small electric version. Yep.

A

Small electric motor, a.

B

A

B

You've got the flow control on the max. Do you ever reduce it? Oh.

A

Control valve, no, we don't need to mm-hmm okay, and we have and the pressure relief we've we've only bottomed or should I say peaked it a couple of times where it binds up and doesn't move oval. That's mainly when we were.

B

A

Winding way out here then way up at the top, and things want to flex and move yeah.

B

A

A

But these yeah, actually these all need a tune-up. Our chains stretched a little bit and we don't have any more adjustment and the fluid in this unit probably needs to be replaced in the filter. Little.

B

A

Been used the lives yep, but here let me find a piece of three.
