Re: Lathe horizontal drive motor and pulleys

Thanks for the understanding of the probable motivation for the design. I have an atlas lathe (also) that has V pulleys on both ends of the motor to counter shaft connection. The large pulley was damaged and I replaced it with a flat pulley of a logan (and it works). The motor on the atlas is on a hinge so shiffting step is relatively easy.

I have a 1975 SB10K with the original countershaft system and guard. It has a two step v-groove motor pulley, flat countershaft pulley and cone pulleys.
I think part of the reason for the flat countershaft is ease of changing v-belt positions because it is a royal pain in the behind to loosen the motor mount to release belt tension.
But with the flat countershaft, the belt can be eased off the side of the countershaft and moved without releasing the tension.
