Mar 25, 2017 cutting the slot on a slotted guard discussion in shop.It usually ends up about 2 thouhs bigger but it is a nice close fit.If i am doing a flat ricasso edge instead round, i use a blind file, it has all the teeth ground off the faces, only the sides cut.That way you do not dig into the sides of the slot you took so much care to get.
