Quill stick at full extension.

Hello,

I'm in the process of re-placing the belt on my 1954. head-stock. In the process I noticed the belt rubbing a waytube. Got me to go ahead a take the motor out to inspect the pan , and motor mounts. That required me to remove the switch, Upon inspection it is damaged..one pole pulls completely out. After doing a search on ebay I find it hard to find a simple 4 pole on/of toggle switch, Where would I find a replacement? The old one has screw-on wire connectors. I also ordered a new pigtail..it has the slide-on connectors. So I guess I would want the new switch to have the slide-on connectors. I could convert the motor to slide-on.

I've also noticed the quill sticks when it is full extension. Is this normal for this year machine? If not what could possibly be the issue?

Thanks,
Ron

The quill has a groove in the top in which a half dog set screw rides. The groove has a slope at the end. IF the set screw rides up onto the slope it will wedge in place. Burrs etc, can make the wedging more likely. I would back out the set screw a 'smidgen'.

Now IF the groove itself has burrs etc. it is best to remove them. Those burrs can be on the bottom of the groove or either side(makes the groove narrower). Not likely but a damaged set screw can also be a culprit.

P.S. The set screw is supposed to just clear the bottom of the groove.
