Some time ago I bought a Powermatic 60 8" jointer to replace my old CM. So now I'm finally going thru it to make sure it's set up right before I use it. The tables aren't coplaner so I was going to shim the outfeed table to the infeed side. Correct, right? Anyway, I loosened up the gib screws. But, I can't lift up any on the end of the outfeed table, which is low. I also can't get the gib to move either so this is apparently frozen up. So what would be my next move here? Am I doing the right things so far? Thanks. Greg
