Free up a very stiff Bridgeport Series 1 Ram

I think that mixture actually used kerosene instead of acetone but yes it does work

IIRC, that’s the main ingredients of Kroil penetrating oil

Has anyone disassembled the 'locking' mechanism? There appears to be some kind of square pin. Is this a locking pin? If so will removing it free up the pincers?
This was premature: I checked both locking pincers and they were free. Whatever is stuck, it is not the pincers.
It is still stuck. I am spraying everywhere about twice per day. I am considering creating an all thread 'press'.

An all thread press is what finally freed mine up.

Mine came unstuck last night. The turret had been removed and the ram had been moved all the way back for better balance. I had been spraying PB Buster and WD-40 into it for days where there were way interfaces I could reach. Finaly it simply 'let' go. I would not call it at all loose, but it is free. For anyone with this problem time, perserverance, and lots of anti seize spray worked in one case.
Thank you all for your help.
