When I was first out of high school, I worked in an automotive machine shop. After drilling out and installing new valve guides in a cylinder head, I was ready to cut new spring seats. After pinning the head to the work bench with the gasket side down, I was ready to cut the seats with a 1/2" drill and seat cutter. The cutter started cutting the valve seat and hung up, spinning my (then 160 lb.) body halfway around the workbench!
