I'm routing (router table) some 1/4" dadoes for box bottoms into soft maple (non-figured) and getting horrific tearout. The dadoes are 3/16" deep. The bit, a 2 flute carbide, seems to be ok on other species.
I've built 3 sets of ends for these finger jointed boxes and I'm losing money on this one for sure by now....
Any advise? I'm about to call it a day and just cut them on the TS with a dado set but the walnut side pieces have stopped dados and I'd like to minimize any potential mismatch, ie, do it all with the same router setup....
Thanks...
