New to me Consew

It's a good start, however most motors appear to come with a 3" pulley, which will only give you a 2:1 reduction. If you fit a 2" to the motor you will get 3:1, an easy option before going to a reducer.

This one comes with a 60mm so in between..... 2.36"....we'll see. I didn't care much for the switch position  but I went for function over form. I can always remote the switch.

I haven't used this one much but the switch isn't a problem (just different to my other servos) as the unit is mounted at the right/front of the table so easy to get to.

?

The one I ordered is the sewquiet. The switch and buttons are on the motor. Which one were you referring to?

AArrrggghhhh! Idiot! I clicked on the link in the wrong post! I'll delete it forthwith!

LOL No worries

My Consew project turned out to be a success. With the 6" pulley on the handwheel and the Sewquiet brushless motor installed it has slowed down to one stitch a second. The motor is set on 5, which is the slowest setting for this motor. The 6" Grizzly pulley I bought takes a 1/2" belt so the 3/8 stock belt sits down in the groove effectively reducing the diameter to 5 1/2" or so. The Sewquiet aluminum pulley is 60mm and the belt fits it fine. Shaft size on the motor is 12mm and It has a 3mm keyway.

I might look more for a 50mm/2" 1/2" pulley with this shaft size but I haven't found one yet. Would be a good thing to get a 1/2" belt on it and with the motor fully retracted the belt is now a bit snug. As it is, it walks through 3/8" of hard Veg Tan leather like it was butter. No hesitations, no grunts, and no odd noises at all it just goes about it's business. I haven't done anything but test sewing on it yet but my wife couldn't wait to do some! The machine is still sitting in the garage and she was out there sewing up some leather purses that were giving her high end quilting machines trouble as they were just too thick to sew. The Consew sewed them easily and she had a big grin on her face.

Very pleased with the results!

I really didn't like how tight the belt was with this setup so I needed to either get a longer belt or a smaller pulley. I wasn't able to find a pulley with a 12mm shaft and 50mm in diameter or really anything close to that so I got one of these 2" and 1/2" shaft.....

With a 1/2" bore it is .7mm larger than 12mm. If the pulley is centered than that's .35mm on each side. I simply put the pulley on the shaft and tightened the set screw not on the keyway area. I had thought of shimming with a cut up soda can since they are really thin, but the amount of runout is not even visible to the eye so I called it good. I also thought I might have to drill and tap in a second setscrew but so far I don't think it's needed.

Since this pulley is designed for a 1/2" V belt, the 3/8" stock belt sinks down in the pulley a bit effectively making it closer to a 1.5-1.75" pulley.  With this pulley installed, the belt had some slack in it and I was able to move the motor back a touch to get just the right tension. The Consew also sews a touch slower now which is always a good thing I think. It's not a drastic change but noticeable. All in all I am very pleased with the results

Hope this info can help someone else out.
