Nancy: Have you ever replaced the BRUSHES on the motor? changing
them and oiling the shaft will do wonders for a used up flexshaft
motor.You can get the parts at swest.I would rebuild the motor
before I buy new. I have a “R” series with the built in reduction
gear,It’s great for stone setting and such.
I might be off base with this, what is the motor doing??
