It’s been a while since I started my Shredder project but didn’t have the time to actually finish it, but I can now say that my shredder is 99% complete (I say 99% because I have not attached the power cable yet, but I already have it)
Here are a few tips:
*Don’t use a motor that is less than 2hp. I purchased a 1/2HP motor and it does shred plastic, but the threaded part of the bottles makes the motor halt. A 2HP or more motor should not have this problem, and if possible, get a triphase one.
*I did not want to buy a perforated sheet of metal because I only needed a small square piece and the hardware store would not sell the amount I needed, so I grabbed a perforated metal sheet I found in an old speaker and it worked just fine (see pictures below)
*On my Shredder’s frame I soldered 4 small pieces of square tube that I can use to put a piece of wood, that will serve as a base for a trash can that will collect all the shredder plastic
*Get a DPDT rocker switch, that will allow you to reverse your shredder motor if the shredder gets jammed
