Table saw heeling
Been at this on and off for 2 weeks now. I have a Ridgid R4512 table saw that is not heeling properly; it consistently is out of alignment by 1/16".
I align the saw's trunnions (bolted to top, not cabinet) to my left miter slot using a combination square and the "pick one tooth" method. To align the blade, I loosen all trunnion bolts and move the rear trunnion to the right (when facing the rear of the saw). When the combination square is equidistant from the slot to the blade (front and rear) I tighten each bolt a little until they are all tight making sure as I am doing it that tightening doesn't move the blade out of alignment. I then make sure the blade is at 90" parallel (using a digital gauge).
A little while ago, I performed the above.... again. This time, I figured I would eliminate the wood not being square as the culprit so I took a board and cut it square using my miter saw. I measured all sides and they were the same length. I took that board to my table saw and cut each side in succession. I numbered each cut as I made it. When I was done, cut #4 was 1/16" wider than cut #2 (turning the board counter-clockwise). As usual, my square becomes a trapezoid. I see that squaring stock on the miter saw didn't provide any advantage.
Any ideas or suggestions on how to fix this? All ideas are welcomed. Thanks for reading.
