I built a pneumatic can crusher, but I wasn’t satisfied with with just crushing it, I wanted to flatten them. So I put it it on a lever, it has ~2.4 mechanical advantage. So it goes from ~160lbs from the cylinder to about 400lbs on the “squishy plate”.
Unfortunately, I was a little too hardcore, after a few tests, it managed to bend the entire base. Once I can get a some thicker metal I will put it back together.
Why do this? Because I have a tiny furnace and a mountain of cans that I melt down and cast into random shit.
Post pics of the output
Cool. What are you casting?
Don’t stick your dick in that!
Wasn’t planning on it before, but challenge accepted!
How do these things work? I cant fathom how its able to do that, it looks like it barely moves? What sorcery is this?
Also is it named after Futurama’s The Crushinstor?
Well the cylinder has a stroke length of ~8 inches (it’s a little less) it is 17 inches from the pivot point, the other arm is 6 inches from the pivot.
When the cylinder is fully extended, the crushing plate will move down about 3 inches which is greater than the width of most cans. (At least greater than all of the cans I have.)
It flattened cans sideways because I wanted to be able to put them through a shredder. It was very close to accomplishing that, if the base plate didn’t bend to shit, I’m sure it would have worked.
Yes! But the crushinator is a big girl, mine couldn’t hold a candle to that, so she squishes instead of crushes!
wirefeed needs a bit of attenuation
Up or down? I’m still learning and trying to figure out the feed.
Also, how did you know it’s the feed? What should I be looking for?
Feeder down or volts up. But I see your welder is Harbor Freight so that may be the best you can get although I have the HF Vulcan that has infinitely adjustable speed and volts. I assume you are using fluxcore wire? And the reason I say feed adjustment is too many bbs
