I have an Incra Pro - I know, it's old but at least I have it, lol. I am learning the dovetail cuts but can't get past the test cuts. When I cut two test boards and turn them around to fit them together (to check depth of cut) I can't get them together - the fit is so tight I have to bang the heck out of em to get them together. I've tried both lowering and raising the bit but still the same problem. Anyone have any suggestions??
