f you are planning on upgrading your machine keep in mind if you buy new they will typically come with a servo motor and if buying used you could buy a servo motor at that time if it has an old clutch motor installed. The only way you are going to get the speed control and punching power is with a speed reducer which will cost about $150 CAD. An off the shelf speed reducer may not still get the speed down to your liking so you probably will have to make your own.

I would suggest you consider putting that money towards upgrading your machine first.

Lots of great info. Didn’t realize the price of a speed reducer. Thanks

another thought: use needle synchronizer

I have a 750W servo motor (brushless) with electronic control box and external synchronizer on the sewing machine. I don't know how many coils it have, it was the upgraded version, but it could be just a PR thing. The low speed is 100 rpm but what actually makes it great is the synchronizer. Pedal down > needle down, pedal up > needle up. There is no problem with speed as I can go step by step when I need it. The needle is always in the perfect position, when the loop is already made (down) or when the thread is unlocked and good to move (up). I used one table with the motor with different machines, each has it's own synchronizer fixed.

Yes. I will probably upgrade so my thinking is get the best servo motor now. The goal is two hands, I just want more control with the same punching power I have with my hand crank.

I found a shop in Victoria bc that sells the sq6000 for 170 cad. I went in person and it’s legit. I’m just wonder if the sq6000 can do what the workhorse can, considering it has 1500 more rpms which make me question the low end speed/torque of the sq6000.

 

 

I'm also in Victoria, and I'd just installed an sq6000 that cost me $315 CDN direct from Reliable. For $170 I'd seriously consider getting another my Singer 196K5... even though that would be 5x what I paid for the Singer.

I have found that the Reliable sq6000 doesn't need a speed reducer. With it's 12 coils it will punch through just about anything I can throw at it. It's plenty slow, and with the positioner I can do one stitch at a time.
