I am Not mechanically inclined but, want to build an electrical aluminum can crusher that will flatten aluminum cans of all sizes thickness from top to bottom. While the Can is being crushed, it can lay on it's side, just as long as it's being crushed from top to bottom. It has to be easy to build on a low budget.
just put them in a trash compactor..
a board, a foot, good balance
just use your foot like i do,pinch the can on the side a little and step on it,works great.
