My mill has a way to disconnect the leadscrew when you want to use the power feed motor for a rotary instead. The leadscrew nut is free to rotate between bearings, with a plunger to lock it. I think that a ballnut held in such an arrangement would spin freely due to their high reverse-efficiency (I could reverse-drive my mill/lathe combo Z feed with the motor and drive attached until I took the rack off) -- atp ------------------------------------------------------------------------------ Beautiful is writing same markup.
