Hi -
So I'm trying to set up a dado stack to cut a 10 deg angle (for a ladder shelf). I've run into a couple issues.
The first comes down to needing a true reference angle. I set my incra V120 miter gauge to 10 deg . I also set a T-bevel gauge to the same angle, using a metal protractor (the one in the photo below).
The two are very close but not the same - probably a degree off. It isn't obvious to me which is the more accurate. I have high quality squares to use for my reference right angle - but I'm not sure what to use for an arbitrary angle like this. What do most people consider the best reference or protractor?
The second problem - once choosing one of the above to set the angle it appears that one side of the dado stack is at the chosen angle but the other side is at a slightly different angle. This is a Freud dado blade on a Dewalt DWE7491RS Table saw. I was careful to make sure the chippers and outside blades are offset from each other. What would cause one outside blade to end up at a different angle?
