Last night my lathe spindle started slipping. Fortunately it wasn't serious. The set screw came loose on the motor pulley. My problem is that when I tightened the set screw, I had no way of knowing if the lower pulley is aligned with the top pulley, so that the belt won't wear. Does anyone know how to properly align these pulleys, or where I can get specs for the alignment? I use a Delta LA 200. Also, I noticed my drive belt is getting quite worn. Where can I get a new belt, either OEM or after market? Thanks for the help.
