Converting a 12x36 lathe to 3-phase power.
#8
Ed,

All I did was counter bore the end of the larger pulley a bit so that the OD of the smaller pulley would fit inside. Much like the register on a lathe chuck / back plate. I needed to thin the end of the larger pulley anyway in order to get the distance between the two sheaves to match the original one-piece double pulley.

Other than that, the set screws (and key ways) hold them in place. And since the hub of the larger pulley (where the set screws were) was hanging off the end of the shaft in open air, there was no way to lock it down. So I just cut off the hub, and drilled & tapped new holes for the set screws in the center of the sheave. Neither pulley has budged since they were installed. Smile
