1st attempt building a shredder (wip)

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!
Attaching some pictures
Good work @tonymake! How did you make them? You said you were sore from grinding– is this all from a grinder? Or just grinding the welds?
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!
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
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
@tonymake did you have any luck building your shredder? We would like to see some photos or a video of the finished machine 🙂
Hi all, people,
Unfortunately i can’t upload pictures (server sayd i can’t 🙁 )
However you can see pictures in my google album: https://goo.gl/photos/pwUaB9SaTPEce7V4A
I’m near the end… but not finished yet
Bye bye
Congrats! shredder looks neat, nice pics. 2HP that’s roughly 1.5kW and 40 rpm that will bring you 358.10 Nm (https://planetcalc.com/1908/). I suppose you won’t have any trouble shredding plastic, although it will take time 🙂
Would be great if you can film the shredding process, in this way the community could grasp what is 358 Nm of torque can do.
hi..
precisation: from gearmotor to shredder i have a 30:21 chain reduction…. so (i think) it is near 57rpm and 250Nm torque.
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 miss the top funnel, the sieve below, and the system to keep the chain tight.
I will keep you informed
bye Bye
