Re: Hex Broach Options?
Paul is more brave than I.........
we use double bushings!
to pass a 3/8" hex through a bearing we buy a bronze bushing from mcmaster at 3/8" ID, 1/2" OD for about $0.12.
we broach it........
then stick the bushing and the shaft into a standard .5" ID bearing. voila! one hex stuck through a round hole........everything is true and round.
putting the hex through a bearing is a fine solution, but for high load application i prefer to have the double bushing to help spread the forces around.
