I just purchased this shaper cutter set for mission style doors. I have read through the instructions and get the basic setup,my groove fits my plywood insert panels perfect. I have the tongue cutter very close,it is bedtime now. My question for anyone who has used this set is , is there a method to center my cuts from both cutters in my stock ? Just wondering if there is a method I do not know yet rather than good old trial and error. Or should I say error and error again. thanks for any help,Mike.
