Pulling Copper From AC Compressors. 

man watching you figure this out has been a thing of beauty. so satisfying watching those half stators getting copper neatly pulled. you can sort them by OD so you have the minimum amount of up and down time with the clamping cylinder

you could even put a small (1/2"-3/4") wide flat on the bottom, it doesnt need to be totally pointed to get through the stators.

I was always good with machines, show me and it will be humming before lunch 😂. Worked a lot of different jobs in my youth. I loved the variety. I remember one job boss came around and said that’s not the way you do it. The job was getting done my way in the same amount of time as the old. What works for one is not necessarily the way it works for someone else. A left handed person does things differently than a right handed person, right? ✌️

My 20 ton press cut a few.laminations some time but the copper still knocks right out

Hi Derek & it's is Randy and i like yours video is Cool & Thanks Derek & Friends Randy

Couple of suggestions. Shape of blade should be like semicircle, not wedge. Bevel must be polished. And you should fix stators tight at the basement to avoid shifting.

I’m not understanding why cutting thru the plates is an issue. It’s not pressing thru them because they are thin and easily cut

Cutting the laminations is not a problem ,as long as you can still remove the copper, which is the objective. The steel is just a bonus for gas money.

It's still beats the hassle of the old process. You just have to sleep on it. All good.

Make a blade guide on the sides of the blade so it will run true and not warp from all the pressure come off your frame to build it😊 awesome work buddy

Good production this time

Nice work man! No dust, no wear and tear on the grinder. The more you use this the more you're getting dialed in. Then the puller has no problem getting the copper out. That's what I'm talking about!

Great video all I can say you are not afraid to try new things

It is,it’s awesome man! Your vision come to light 😊 Maybe you could make a concave blade to sort of wrap around that one with the shaft the ID a little larger than the shaft

Nice setup! Have you thought maybe some big all thread tapped to welded bolts in a jig frame on you base to level? You may need a to level as u go given the force you are getting out of the cylinder. I learned in farming when I was young., Powerful hydraulic cylinders do have the ability to completely warp the cylinder arm. Happened more than once on the front loader on a tractor. The whole cylinder warped.

that blade can take it, if anything just put a radius on the tip to make it stronger and roll with it. that steel they use for stators is soft as butter.

I think the proper term for the "things" or "plates" as you call them, is laminations.

Hi Derek when you make the new blade in the center of the cutting edge put a half circle to bottom out on the shaft.

nice job it works so damn good im glad ypur getting it working to get that copper thanks for shareing

On the bigger ones. Cut as far as it goes. Slide the metal Vs in there to raise it up and give it another cut.

I think the angle and point of the blade are the main issue. It's because the point of the blade goes into the bottom of the center opening before the side of the blade spreads it apart. The point is starting in a different row of plates on the bottom half forcing it to cut through them. If the point was shorter the sides of the blade would split it enough for the point to go in the same gap it started. So less angle on the blade or a semi-circle blade shape would fix ya right up 😊 Eta: if this doesn't make any sense just look in the opening of the stator and watch the tip of the blade while cutting...

Save $$ on making a new blade you don't need one. You have everything you need in-house to just press those shafts out.

A note for the editor. When you go x2-3 speed the audio does not and becomes disjointed from what we are seeing. It might be better to hold with your music tradition from your timelapse camera or to just mute during that speed up period.

Your plates are shifting, Tack weld the left plate

Would like to see how you cut the ac compressors. Nice haul.

If you use a hydraulic press to push the axle out of the rotor you can split them just like a stator ❤ I do it with smaller motors all the time

Have you seen the log splitter cutter video? He had a 3-chain puller that could pull those small ones in 1 pull.

The blade is going to follow the path of least resistance with no blocks on the ends of the motors.

At 35:30 as you push down the whole press rocks to the right side. This probably also rocks when you have the blade in it. That’s why it wasn’t cutting straight down. The more force you put, the more it rocks to the right.

for those rotors you could just use the press and like a good metal handle hatchet

assuming the blade is a uniform thickness past the beveled edge, you could make a fixed blade guide that will stabilize it and reduce the lever arm on the blade when cutting. im glad you are thinking about that because as you currently have it, you could have quite the bending moment on the blade if you arent careful. id find two pieces of channel steel, attach uhmw to the flat faces, then figure out a way to fasten them securely to the press frame so that they guide the blade. you have a nice mill now though, so you should be able to fabricate something nice!

I think you might have just paid for the cutter, press, and puller! Buttery smooth and safer!

Yo man! nice to see you getting better and better at dyling in that gigantic press. Please modify that pulling thing, bend the handles out so they don't cross / touch when closed. My as hurts from sqinching every time you grab that thing.

Hey project shop on Camry that played for the splitter looks like it's bent toward the tip of it and it shows that spent to the left or the back wall😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁

Looking good mate. Coukd it be that the laminated steel in stators aren't straight? Good to see that you're trying new things, to get the bucks😎👏👏👏👏

You need a straight or round blade. I was impressed with what it did.

I think it's because everything on the table moves especially the v'stheres nothing really pushing the blade!

What the hell difference does it make if its not cutting perfectly straight ? All long as it cut's in in half you've accomplished want you want.

The rotor shafts can be pressed out then you should be able to split them

might have to box in the stators like you do the transformers

I don't know if it's the straightness of the cut, or the act of separating the laminations. it looks like when the laminations split, the blade's thickness isn't perfectly centered due to differences in the glue strength holding them together, so it walks a bit sideways on some and not others.

Try leveling out the table. Because the blade mounts are coming down on the stator lopsided

Your slowly but surely getting the shear lined out .

Put the camera Square to the blade right in front of it so you can see what's happening

The v plates its sitting on are lifting at the ends as they're pushed down in middle, need to secure those v plates that stator sits on

Muy buenas en vez de que la cuquilla termina en punta de flecha, mejor iría en forma de media luna los cortes serán precisos un saludo de Canarias

Concave blade!

For what its worth i think the slop is coming from the frame of the press. HDPE glides could help?

I'm wondering if as the thickness of the blade comes down it's putting uneven pressure against to the plates to the windings starting from the top. Both halves of the stator are tilting slightly causing the crooked cut

Ive seen few scrappers with cheap mechetti knife and a hammer to split them Stators. Maybe u can use that with your press ?

looks like left side of the press is warped

Just cut the rotors with a cutoff wheel

It's cutting them in half so why worry about it

@40:12 look at the whole left side lift up. Is this why your cutting crooked?

Have you figured out how much you make on one compressor

Is it possible to press the axl out first?

🎉what is up with ur camera?

Grinds are off " who cares" ?

Ur soo close dude..a sharp blade for sure..about 3/4 of an inch above the blade needs to be wider..let the hydrolics spread the housing and the blade will easily cut the Cooper..did u ever cut a tire and if u spread it open when cutting its easier to cut? Same concept..let the fat part of the blade do the work and save the blade for the gold..too easy..😊
