After noticing a slight degradation of the cut quality on my miter saw decided to change the blade only to notice what I believe is excessive run out. Checking the previous blade as well as several others yielded the same 0.017” of wobble measured at a radius of about 4.5” from the center. The saw was manufactured in 2005 and has been used sparingly only in my shop, never on a job site so the possibility of abused is beyond unlikely. Calling Ridgid directly to get a spec on the arbor resulting in a waste of 28 minutes and zero addition information beyond what I already knew. Has anyone experienced run out on any miter saw that resulted in visible blade wobble and degraded cut quality?

Have you checked the blade and blade bushing. I had an issue once that the blade bushing did not seat square and had similar results. You could also have a blade that is warped.

The blade was eliminated from the equation by testing with 5 other known good blades. I’ve never seen a 10” mitersaw with a blade bushing, only seen them on 12” saws, mine does not have one. The issue turned out to be the inner arbor washer. It is of a low quality stamped steel design and must have some how been damaged. After replacement my measured runout on the plate just below the gullets was a consistent 0.003” with several different blades.
