I made this can crusher using Bicycle gears, bicycle crank arms, bicycle chains, a treadmill motor and lots of other stuff I already had on hand.
I have a web page showing how I made the MC-2100 treadmill motor speed control. Here's the link

Note: I do not make these treadmill control boxes
I only made this one for me to get my can crusher working.
Please do not email me and ask if I can build you one.
