Stop motion clamp frozen - featherweight in sad condition
 

I recently purchased a white featherweight. It is in sad condition. I will
eventually have to strip the paint, sand, prime and repaint. I am slowly taking
off pieces and cleaning them. I am waiting on Dave McCallum's featherweight
book and DVD's before doing too much.

My biggest problem at this point is the stop motion clamp/knob. It is frozen. I
have sprayed the gap between the clamp and the hand wheel with liquid wrench and
PB penetrating catalyst. I stood the machine on the extension plate end and
hoped that the lubricant would soak in and loosen the gunk. I also tried
turning it with a pipe wrench but I could not get a grip on it with my pipe
wrench - maybe my pipe wrench is too big?

I would love to get this cleaned up and working but I am not sure if I can
restore this machine.

Anyone have any suggestions on the stop motion clamp?

On the tough ones I use curved jaw "vise grips" cushioned with scrap leather or old belt.

Triflow and a hot hair dryer might do it. Let the Triflow sit on it for a day or so - then add more Triflow and then apply the hot air.

Did you get the screw out of it, otherwise it is holding it.

The screw is out. So far no movement on the stop motion clamp.

Stop motion wheel unfrozen! YEAH!!! Took a week of standing on end with liquid wrench filling balance wheel. Ordered V-jaw channel lock pliers. When they arrived today, I rocked the stop motion wheel back and forth a little and off it came.

Now the hand/balance wheel won't come off. This time I am trying PB penetrating catalyst and time.
