I built this can smasher quite a few yrs ago with stuff that I had around mostly. The hubs are from a bent axle off a trailer that I got for free from a local trailer repair shop, and the bolts that I used I had to buy from Napa for like $10. Everything else I had was laying around/ found in wondering through the earth. It has served me very well, as I can smash a 30 gallon barrel of can in about 2 minutes. The only caveat that I have, and have not really tried to fix, is they have to sit out and dry to run through. if the tires get wet the cans don't get grabbed and pulled through, but I have a stick for the few times that seems to happen.
