Topic tags/keywords: alignment trunnion g0576 table saw

It was my fault, I (stupidly) stuck a piece of angle iron on the back undercarriage of my Grizzly G0576 Contractors Table Saw to use to pop out my zero clearance insert. When I adjusted the blade for a 45 degree cut it bumped into the angle iron and knocked off the blade alignment. I realigned the blade as per instructions with the trunnion alignment kit I had previously installed on the saw. The blade did align but just barely, I didn’t have another thousandths of an inch to go so I knew there was trouble. Yesterday I tried to adjust to 45 degree cut angle and it never got to the stop but was in a bind like before with the angle iron but there was nothing for it to bind upon. When I looked at the blade it was up against the table where the dog supports the zero clearance insert. I have taken off everything I could to better see the problem (motor, blade & attachment bolts to the stand) but I can see nothing wrong. I was about to put a binder on the motor mount and turn the angle wheel in the opposite direction to see if the blade moves in the other direction and try to determine what actually moved, then I thought I’d prevail upon maybe better minds than mine. So I’m here.

There’s a chance that the connecting rods have twisted within the trunnion brackets. If that turns out to be the case, there some effective remedies on the web if you Google for them.

I’m nearly certain this is the case, thank you for you advice. I hope I find something.

not a nightmare, I grew up in a machine shop myself. I love it when something goes awry, so long as I can figure it out. This one has really got me stumped. I had the Pals trunnion adjusters on the saw before this happened. But now the bar out the back above the motor hits the trunnion bolts and won’t go to 45 degrees. I put a flat plate on the internal bars when level and it was only off a thirty second of an inch, not enough to make the bar miss the trunnion bolts. I took the bar off as I don’t use the blade guard anyway and the saw zeroed and goes to 45 degrees now, if I ever figure out how to fix it perfectly I’ll come back to it.
