Problem with post vise

[Mike Turner]

OK I stuck a rod in the hole on the box and marked it for length and it looks like there is about 3" of thread stuck in the box. I clamped it down and put a 4' pipe over the handle to see if I could move it not a chance all I did was straighten out some of the bend . I have it soaking in penetrating oil and will give it a try again tomorrow, if that don't work I will get a friend to help with the heating process.

Hi --- I had one like that had a damaged thread after getting it out useing a gas touch it heat it--- i cut a groove like a gap along the lenght of the nut -- I also deepened the thread on the bolt with a disc grinder--- then closed up the gap in the nut and welded up the groove = OK a don't lean on the handal to much ----

--- When you heat it use never-seze --- you could even fit a grease nippel on to the nut then pump never seaze in then heat the nut ----

right I see the crack in the nut I would use a disc grinder with a cutting disc and cut the crack open -------undo the nut&bolt---file things up to a good fit---- vee out the now cut crack PUT NEVER SEZE on the nut&bolt clamp it onto the bolt then weld the vee up on the nut ---{{{ do not breath in the smoke }}} Let things cool before you turn them----

Remember a good weld can only be done with a good fit up

What penetrating oil are you using? Not a good idea to leave things soaking in some brands. I am not sure about US brands but somebody here will be. Did you try the warm, used engine oil? It absolutely cannot harm.
