Topic tags/keywords: table saw blade table saw alignment

I have a new cabinet saw. Not sure but is this ok so I have a digital calibrator. I Zero out at back of saw and move to front while rotating blade to point of the calibrator hits the exact same spot on blade in front. Says I am . 001000. It 10,000th of an inch off, is that ok? I have ready that 3000th of an inch is acceptable?

It looks to me like it’s off by .001”....and that’s fine (excellent, really). If it’s off by .00001 that’s NASA precision. But the way to tell if the saw is off is to cut a piece of wood and see what the results are.

Agree with Fred above
Also, which miter slot are you measuring from? Some people actually set their saw up to be a thousandth or so further from the fence at the back of the blade to help mitigate risk of pinching/kickback

Don’t worry about numbers unless the cut is off. A few thou here or there mox nix as long as the cuts are right. How do you think the oldtimers did things without DRO’s?

Thanks. I measured on both sides. On the rip fence side was . 0010 on the other side, the left side of the blade . 0030

Put it into perspective, .003” is about the dia of a human hair, the thickness of a sheet of paper, or the limit of the human eye resolution at the standard ‘reading’ distance of 14”. If that’s your biggest error no-one will ever see it.

I spent several hours…like a crazy person amount of hours…dialing in my jobsite saw to .001 and i still make bad cuts with it. I get lazy and dont use my feather boards or rip block and presto magico my cut is off. Only happens with longer stock because my fence is so short but i guess my point was don’t sweat the small stuff.

When I calibrated my saw I just used a regular dial indicator. Starting at the back or front zero out the indicator. Rotate blade to check for run out and fix if necessary. Checking parallelism rotate blade to find lowest spot and zero out indicator. Move indicator to front or back (depending on where you start) do not rotate blade and note reading on indicator, + or -. Within .005 is fine. Don’t know what saw you have so .005 might be the best you’re going to get. You could always loosen the table and try to tap it straighter.
