I have been using the magnetic ruler trick to check that the blade is parallel to the fence:
That method, as revealed by the tune-up done today using a dial indicator, isn’t very accurate.
I checked two settings of my Ridgid table saw: alignments of the miter slots to the blade, and to the fence.
The slots and the blade are accurate within 0.001”:
The slot and fence were way off by about 0.003” (that was also the factory setting!):
I immediately made adjustments to the the rip fence:
The alignment is close to perfect:
Close, because I found out the rip fence isn’t really dead-on uniformly straight along its face, or may be the miter slot isn’t. Since the error is within 0.001”, I am not going to worry about it. (Human hair is about 0.0039” in diameter.)
A dial indicator is a useful tool to double check or verify your settings.
