[AT] 39 Farmall A crankshaft question

[Al Jones]

I had thought about it.  Problem is the shop is small (Southern Autoparts in Jacksonville) and there's 25 in the class.  I still think I will take a look at the possibilities.  The machinist there seems like an outgoing sort of fellow that wouldn't mind showing students what to do.
