Members glennaycock Posted October 20, 2010 Members Report Posted October 20, 2010 I was under the impression that the Seiko STH-8BLD-3 was identical to the Consew 206RB-5, possibly even made in the same factory. I went with the Consew for upholstery and general leather sewing. I also ordered a SewPro 500GR and 2" pulley, which I'm hoping will give me excellent control and torque at low speeds. I received and installed the 500GR, but I haven't gotten the 2" pulley yet. It does have a lot more torque on the low end than the other servo motor, and I'm able to do 1-2 stitches/sec by barely pressing the pedal. However, it's still very fast with just a bit more pedal. Still, a good investment I think. Hopefully the 2" pulley will make even more improvement. I tried adjusting the brake, but could not break the spring-bolt by hand and didn't want to strip it. Quote

Hopefully the 2" pulley will make even more improvement. My SewPro 500GR servo motor, purchased from Toledo Industrial Sewing Machines, came equipped with a 50 mm, a.k.a. 2" pulley. What size is on yours? Where did you buy it? You can reduce the pot setting on the back of the motor for slower top speed. Just stay above 50% and you'll be fine.

I got it on ebay directly from SewPro (I think). The pot is turned all the way down. I'm still waiting for my 2" pulley. Hopefully it will arrive tomorrow. Thanks, Glenn Quote

That motor has a smaller diameter shaft than clutch motors and big servo motors.
