Hi All,
I was just given a Shopsmith by a friend. It is a Mark V. I am fairly certain it is the base model as there are no additional tables besides the primary saw table.
Anyway, the problem I am having is removing the quick change arbor from the spindle. I have removed the set screw, sprayed everything down with WD-40 but it will not budge.
Based on the self study course and the Shopsmith book that came with the saw it seems like it should just slide off.
I currently have the motor rails in the vertical position and some cushions under the spindle area in case it should decide to come free.
Any thoughts on what else I can do or should do?
Attached are some pictures for clarification.

Looks to have been made in 1982 for starters. Ya need to use some different penetrate. Like PB Blaster, kroil oil, etc. That arbor SHOULD just slide off with a POP. The tolerances are that tight. Does it move any on the spindle?

It appears that you have the arbor rusted to the spindle. You likely need some penetrating oil like Kroil, Liquid Wrench, or PB Blaster instead of the WD-40. Give the stuff some time to work (overnight or longer), keeping the Shopsmith in the vertical position. Some light taps with a small, soft hammer on the arbor might help.

I was just wondering if ya dripped evoporust into the arbor. IF that wood better than some penetrating oil?

I had to use a gear puller to get mine off. It was rusted just about like that. After it came off I cleaned it up with a brass brush and it worked great after that. The tolerances are so close that a tiny bit of rust locks it right up

Thanks for the quick posts. Wood unites. I'll try some actual penetrating oil. I have given the refurbish project to my 20 year old son while he waits for his Air Force BMTS start date. Once we get it all cleaned up and the books studied I think we'll be looking to add some functionality to it. First I'm gonna read some posts to see what the pros do.

Used PJ and borrowed a jaw type puller from Napa

Man, was that ever seized on!. Had to keep using the wrench on the bolt until it was completely removed. Never would have come off with just the rust buster.
Starting a new thread for the next challenge. The miter guide rail.
