Galled Stainless Steel machinist jack??

[Janderso]

This is all good to know. I also use too much stainless!
So ya'lll don't think that freezing the screw with dry ice and heating the base with a torch would yield any result? Is galling really welding?
Full disclosure...here is my ill-conceived stainless machinist jack!

Followup question: Does passivation help prevent galling?

Beautiful finish

Once stainless starts galling to itself it's nearly impossible to get them apart without doing serious damage to the threads.

You can take that to the bank.
