Hey! Got a new sewing maching but the damn thing runs way too fast and the clutch is in or out- no speed control. So I decided to turn the motor into a jack shaft for speed reduction.

Here's a new shaft I made to replace the armature. It is 3 inches longer on the right end, this will stick out of the motor housing for a pulley.

The bearings are a press fit.

This is the clutch face, note the pulley on the back end of the motor.

I got a motor off the motor pile and an old door hinge and hung it on the back support of the table. The electrics in the old motor I just taped up to the outside of the housing. It still ran too fast so I put an even bigger pulley on it!

I have to make some equipment guards for this. Wouldn't look too good if a bedsheet or something else got wrapped up in the pulleys.

The speed reduction also gave it some punch through power. Goes through many layers of heavy duck…
