When I input the info for build doors in house, I input 1/8 for machining allowance. On my cutlist, Some of the stiles only have the 1/8" added to them, which is what I want. Other stiles and all the rails have 1/4" added to them. So far all the problems I've encountered have been my own fault, so I don't expect this to be any different. But if someone could give me a clue to correct it, it would sure be nice.
