I recently got a 1950-1960 (not quite sure on year) Shopsmith Mark V Model 500 from my grandfather as a gift and i just started using the lathe yesterday and it worked just fine but then today when i went to take the lathe chuck out of the quill and somehow overnight it became stuck. i have tryed several methods of trying and getting it off and i cant get to far. anyone got some adivce or ideas.

Spray some lube in the screw hole and try to work it off. That chuck is a tight fit on the spindle. Either ya have some corrosion, a burr or dirt in the hole.

Stuck chuck

Hey, all!

To unstick anything (well, almost) check out the products from Kano Labs in Nashville, Tn. Their Kroil and Silikroil are great for this and well worth having around the shop. Spray some on and come back in a while and many stuck components slide right off. Highly recommended!

From the photo's, it looks like you have it off most of the way. Try what the others have suggested first (penetrating oil). Have you tried tapping it back in a little. Perhaps something is jammed in the flat part of the shaft and as you try to pull it out it is getting tighter. My next step would be to put the sanding disk on the other side so that you would have some leverage and use vise grips to try and spin it off. If it is still too tight I would then use a propane torch to heat it up a little so that it expands enough to tap it off. Don't get it red hot or anything near that, just hot enough to expand it a little. A little heat has done wonders for me getting things apart.

ya its been a couple of days till i got to it but your idea worked, i did not have a blow torch so i used a heat gun and it worked but now for some reason i cant get anything (including ones that worked before) on there. it is cooled down but i think i might just give it a day but do you have any ideas on some thing like that

I don't believe that having applied heat to heat has anything to do with it being tight now. I would guess that whatever caused the original problem is what is causing your inability to slide something onto the shaft now.

I would turn it on (slow) and use a piece of crocus cloth (fine grit) to polish up the shaft and eliminate a burrs that might have developed.

Then I would do the same thing (manually) to clean up the inside of anything that you are trying to put on the shaft.
