I recently purchased an old DJ20 at auction and am excited to get it back into shape. This is a new activity for me -- don't have a lot of experience fixing up old machine tools beyond sharpening and polishing...

There's been some obvious prior damage to the guard, where the red "pork chop" has been crudely welded back together after something dire happened to it. It still swings well and I can successfully adjust the spring, tighten the swing, all that. However, it occasionally just grazes the outfeed table and I would like to raise it 1/16" or 1/8". My reading (Delta but better, Grizzly G0490 manuals) is I should remove the guard, then loosen the setscrew on the front of the jointer face, raising the post into which the guard is pinned slightly, retightening. (See photo.) But this isn't working for me. I loosen (or remove) the setscrew and can then rotate the post in its socket -- not particularly easily but enough to twist in either direction past the "flat part" which has to face the screw before retightening -- but I can't for the life of me raise that post at all from its socket. I assume whatever terrible thing happened to the guard perhaps bent this post a bit and it's not a smooth fit. I have tried lots of WD-40 and liquid wrench and a variety of ways of grasping the mushroom cap to "lift," but wondered if you had any advice about budging it vertically without risking bending it further. The bolt is captive in the cast iron jointer base so I doesn't seem like I can access it anywhere except from the top.

Any suggestions?

Thanks,
Nick

ps. Separate request -- reading old DJ20 posts I see repeated mention to a supplemental Delta technical document on adjusting table parallelism, but all of the links to it (direct to Delta or to third party) are now obsolete. Does anyone have this document who might share an electronic copy with me? The Grizzly manual covers the procedure and may be superior, but I'd like to cross-reference it against Delta's description if possible. Thank you!
