David it is very expensive to have those tools made by a machinist, (150 $ at last, plus taxes for the washer maker for instance) You can align with different methods I've find that the Jahn's method works fine with the keys that have that cylindrical hole inside, centering on a worn balance hole may be more difficult, but I have done it with enough success as well (I modified the Jahn's tool to use with thinner pilots also). If misaligned it is always possible to go back and replace the washer nowadays. There is certainly another method using wood at the bottom of the key and drilling a new balance hole before gluing or after that (I recall a procedure in the journal a few years ago).

It seems that you must be paying for the information. The tricky part, as I see it, is when there is substantial fore and aft play and the hole center must be reestablished. I can't quite envision an easy method to accomplish that.
