My table saw’s arbor has a gap between the “shelf” that the normal blade rides on and the beginning of the screw threads. This gap is just wide enough for a dado chipper to “fall” into, thus cutting deeper than the rest of the dado. (Otherwise, the arbor is uniform thickness.)
I hear that you have studied this problem. Other than replacing the arbor, have you found a DIY solution?
It has been suggested that I shim between the fixed flange and the inside dado blade, thus putting the full dado on the screw portion of the arbor. Would this be a safe solution? What about just enough shim to allow the outside blade & the first chipper to bridge the gap?.
