Sounds like a great idea. Are you using this just to bore deeper for input clearance and still using the adapter bushing?

I then inserted the drill bit into the tubing and drilled the tailshaft to the proper depth to fit the bushing.
I have drilled 7 to 10 engines with this jig (I even did one with the engine installed) I have never had an issue with it.
I just drilled the forged crank on a 68" Toronado 455 (on my Garage Floor, with out disassembling the engine) to put into my 64 F-85 .
