Reduce, reuse, recycle! Less speed, more POWER (theoretically at least..)


Wheels of plywood turned on lathe. Looks much easier on Y-tube than it is ...
Ballbearings from old skateboard.
Yes, it works. No, its not accurate.

pity were in the wrong countries joe , I have 2 complete clutched sewing machine motors lying around

Yeah, it's about half the world between . Sewing machine motors over here seam to be either crap or high end (=priced).
(Or i am too dumb to find...?)
Had an old Pfaff motor, but the kids blew it at full speed sewing cardboard.... ... it was too fast anyway...

Clutch industrial motors are built for the experts that can handle the eye watering speed and that is not me
Going slow by slipping the clutch doesnt seem sustainable to me so reducing the speed is a must
The one I had was either stopped or doing close to 3000 stitches per minute The difference was about a hairs breadth on the pedal

A servo motor is the best way to control speed and accuracy on any "industrial" type machine. If you invest in a commercial machine then take it to the next step to make it completely controllable and replace the clutch motor with a servo motor.....

A servo motor completely transformed my Bernina 217 to very controllable machine

I still have a Singer 491 I don't use here, that is exactly like you described above.

Can you tell us the make, model and/or specs of the servo motor you used? Thanks

Hi Barney
Here it is I added a smaller 40mm pulley to it as well as I like to go real slow at times and it still has plenty of speed
More than I could ever use





I see the 110 volt equivalent motor is listed on Ebay as FESM 550 $110 USD

There are many small machines with small motors here available for cheap. The motors are fast but dont have power.
I found pics of speed reducers, but they are not available in germany some how, so DIY!
My last machine is a Paff 138 with old motor and heavy flywheel. Havent pushed it to the thickness-limit yet...

The picture above looks like a servo motor coupled to the reducer
That would be a great setup for sails coupled to the right machine
