does anyone have any suggestions on how to get this shaft out?
My saw (Rockwell contractor saw) has been very hard to raise the
blade, so breaking it down the reason lies here. It won't move.
I've used some penetrating oil to try to loosen it up, no help so
far
take it to a machine shop and have it pressed out?
suggestions?
TIA


How much force have you put to it?

smacked it with a hammer(16oz) at least a dozen times with a slightly
smaller diameter steel rod, moved about a 1/16th of an inch


It looks like you might have already tried to get some penetrating oil in
there - seems like the pics show some signs of that. I would try throwing
some heat at it if you have that capability. That's a lot of cast iron to
absorb heat, so a propane or a map torch might not be enough heat. Then
again... I have surprised myself in the past at the results of using map gas
when I was certain that I'd need to hit the object with my acetelene torch.
It's worth the attempt. Try to heat the pin. Ultimately, you would want to
get the pin red hot if you could.
