Flip it over and oil the screw and bearing point, flip it back and oil the slide points then work it back and forth until it's free.im going to attempt my own record vice this weekend, I does not have a quick release so it more like the one in the link above. it works ok but if I have something in the vice and then undo it I can turn the handle out a few turns before the jack quickly springs back, sound like it just needs a clean and lube?
ive installed 2 bath rooms a down stairs toilet the hall and stairs 4 bedrooms the extension and the front room and landscaped the front and back gardens
and you fixed a vice
I was thinking he'd rushed it a bit.
