I'm wondering how folks are doing these.... I'm using the 4mm Domino cutter, and have the depth set at 20mm...because the bit is shorter it is correctly cutting a 10mm deep mortise...but this just barely pokes through the other side of the wood. And yes, I've set the 45 degree angle before lowering the fence. Seems like some sort of spacer is needed under the fence...?maybe in the 4-6mm range....if someone has worked all this out it would be useful hear what works well..Thanks!
