[AT] O.T. Woodruff vs straight keys

[joehardy at epix.net]

 My brother is rebuilding a corn chopper and having difficulty replacing bearings on the pick up head. Couldn't get to slide the bevel gears off drive shaft. He asked me why woodruff keys were used instead of straight keys. Thought I'd throw his question out to our group. Ref: Read discussion on Practical Machinist. Joe Hardisky, Ryman Farm, Dallas, PA
