Keeping the freshman busy is to have them cut drive shaft that has the special coating and the hard stuff, not soft. She got about 1/8 into it before I had to take over and I got another 1/8 into before I had to leave. We only have a hacksaw. And then they decided not to use it altogether so that was a waste of an evening for me but it was fun.
Sorting out the drill bits is another fun task!
