Aligning blade parallel to the miter slot

[Brian Runau]

Ok. I am using a digialign and calibration disc. I checked the run out on the arbor and it was .005 or less. With the calibration disc it is within .005 which is great. Using a used freud diablo blade or a used Forrest blade I am sometimes getting .0025 or even .0035. Varies. Same set I was using on the calibration disc. Top is tight etc....

Could a used blade, that seems to still cut well, be warped this much?

Thanks.

Blade runout will be larger than arbor runout. Are you sure about your numbers?

0.005" for arbor runout is a huge. 0.0025 - 0.0035 for blade runout isn't bad at all.

I'm retired, I can't do math anymore. 1/2 of one thousands should be another decimal. .0005. Sorry brian

Check the cut, that's what matters in the end

Mine is right around 0.001 (SawStop + Ridge Carbide blades) but if it were 0.002-0.003 I wouldn’t even worry about it.

I’m with Edward, the cut is what matters.

I contacted Sawstop with a run out of 0.009" and they said that was within tolerance and the cut was smooth and straight. I adjusted it to 0.004" and the quality of cut remained the same, so I think 0.005" is fine. Go and make something!

Cut it precision size today, and tomorrow it will be a different size. DAMHIK, but I do!

Clock the blade and measure runout. When you find the position that yields the least runout figure how to mark it and be able to return it to that angler position when reinstalled.
