That sounds really good. I spoke to Reliable's customer support about an hour ago. Nathen advised they had run into this issue before. He stated that the sales person should have known to advise me I would want the 2 inch pulley. Will double torque delivered to the machine and cut the speed in half. There is no doubt it will help. I just took the belt off and ran the motor at all speeds including the very slowest. With no load it runs perfectly smooth at a consistent speed. My Adler 267 has a 3 1/2 inch pulley. The servo pulley is 3 1/2 inch also which means the machine head is geared with a 1 to1 ratio. Hopefully under driving it with a ratio of 2 to 1 will solve the problem. It will effect top speed of course but that is of no concern to me. being a "hobbiest" I need control not speed.
Hey, I am almost 67. How much time do I have to practice? I NEED CONTROL NOW!!!
