I made some can crushers quite awhile back only mine weren't automated and only did one can at a time.
I ended up making about 25 or 30 of them. Sold about 12 of them @ $50.00 each and gave the rest away to family and friends.
The nice thing about them is that you simply put the can into the crusher, pull the handle down and it crushes the can and it drops out of the back into a bucket or trash can below.
They looked nice enough that people wanted them to put on a deck or patio or game room.
They have held up very well. I have one of the first ones in my shop and it has been going strong since 2008 or so. It gets used 5 or six times a day every day.
