I've tried the kits and know what Michael is talking about. Using a larger indexing bit to center the cutter does not necessarily place the balance hole so that the fronts of the keys align. The new insert has to be indexed off the front or someplace else like the bachckeck notch or rear of the key. A worn balance rail hole offers no accuracy because you can not be certain if it is mostly compressed at the rear or the front, or left to right for that matter for alignment the keys at the rear. I've had to deal with misplaced balance holes due to other's fault and at my own hand. I don't see Michael's advise as a tutorial to JD but as general info to the list.
