Hello. I have a Delta contractors saw, and after years of using a hammer and block of wood to align it I finally broke down and bought the PALS Alignment System. I got the blade aligned to within a few thousandths of an inch. I then tilted the blade to a 45-degree angle and checked the alignment again, but found it was 1/100th of an inch off. What would cause it to be more out of alignment when tilted to a 45-degree angle? I considered trying to align it while tilted, but I'm assuming it would mess up the alignment when the blade is back at 90 degrees. I'm sure this is going to be complicated to fix, and will cost me what little sanity I have left. Any suggestions or help would be much appreciated. Thanks in advance.
