question on aligning the arbor on a table saw. with a dial caliper i’ve measured the variance 2 ways
1 – measuring the distance from the mitre track to near saw blade tooth at the front of the table saw. then rotating the blade and moving the caliper to the back of the table saw, and measuring again to the same spot near the same saw tooth. when i do this for several different teeth, i get a variance of 1 to 2 thousandths. is this amount decent?

2 – i measure the distance from the mitre track to near a saw tooth at the front of the saw. then WITHOUT rotating the blade, move the caliper to the back of the table saw measure again (this time to a different tooth since i didn’t rotate the blade). the variance i get here is dependant upon where i start on the blade. but sometime the variance is up to 5 thousandths.

i would think the difference between method 1 and 2 above is that 2 also include any variance due to the blade not being perfectly flat (i’ve used 2 fairly new Freund blades, albeit not their most expensive ones).

what do you guys think? do i need to do anything about this?

I use method 1 and would be satisfied with a difference of only 0.002”.

Use method 1. 0.002” is good. Also make sure u are doing method 1 with the belt on as it can make a difference.

Have your say...
