From the submitter:
"Wife asked for a new meat grinder with electric motor. I saved some money and made one from hand-powered grinder and drill. The best part is that I was allowed to buy a new drill and leave the old one for meat grinding."
So we put a burger patty grill on yo' muffler so you can grill while you drive!
Just fasten the attachment to the muffler and drive for a while. Thankfully no exhaust actually comes into contact with the patty: the hot air is used to heat a metal plate between the two instead. It's a good thing too, because that would be one smokehouse style burger I would not want to touch!
