After the kindly assistance yesterday from Paul, I was able to get my dado brake cartridge installed. Today I started installing the dado blades. After sliding the first one on it was apparent that the cartridge gap needed to increase. After adjusting it as far as it would go the yellow gap tool was still contacting the blade. My dado set is an 8" Freud Super Dado and after measuring one of the blades the obvious problem was that the diameter was actually 8 1/8" !!! Now I know why it has taken 8 years of SawStop ownership to use my dado set for the first time.
I really don't want to buy another dado set but don't want to risk triggering a $130 dado cartridge and ruining the blade to boot.
Has anyone found a work around for this problem?
