A Great Deal
I bought 3 of these dual shaft stepper motors as an upgrade for a 1998 Sherline Mill. These replaced 86 oz in steppers, and have enough power to easily lift the Z axis. They work great!! I do art carvings and these stepper motors run for 6+ hours at a go. I must be getting close to the 100 hour mark without issue. I am giving five stars because for the price these steppers are a super value. I am ordering another one as part of an Emco Compact 5 lathe conversion. -Tim
