hi..

teorically….!
keep in mind i have a very aged motor… i suppose it have a very low efficiency.
now i’m only testing it…
I tried shredding a few bottle cap
It reduces them shattered very easily.
Now I…[Read more] -

Hello, unfortunately on the plate of the hoist is only written: 1400 rpm and 2 hp.
But turning it by hand I saw that the reduction ratio is 36 or 37 … so the final shaft should be about 40rpm. Maybe there are few … but to get started okay. -

I finally found the way to power the shredder: I found an old hoist and I’ve eliminated everything I did not need. Still under construction. Look at the photos

To Jegor:
I do not know yet. But I think I would build a 25 / 30mm iron tubular frame. It should not be difficult. I have to find the gearmotor first … then build the frame … of the right size. As soon as I realize it, I will post some photos -

To Trent:
I made it by laser cut (my friend have a very big machine)It was very hard to grind the various pieces because the project needed 5mm and 6mm thicknesses … but my dimensions were thicker. They should have a thickness of 149mm … instead I had 153 !!! I have sanded well 3mm of steel! Twice!

I made this…. is not shining like your… but it was very difficult… all the pieces has to be grinded a lot… my fingers are burning… but… I’VE done it! Now i’m looking for a good motor and a gear reduction…
I said… work in progress. ..
See you soon!
