I had a good file, but still, two hours with my arms over my head and stopping every few minutes to dial-caliper it to find the high spots made your word "drudgery" extremely appropriate.  By the way, those high quality die-nuts are great, as opposed to those flimsey set screw housing Chinese dies that come in a tin-box set.  One good M12 x 1.5 die-nut cost $17 at a machinery supply house but it was worth it.

I discovered, by stipping some 10mm head bolts a a Porsche, that the bolt sizes are engineeringly chosen so when you stip the threads, the very next larger size will have enough metal to re-thread for the next larger nut or bolt.  Sort of a ureika moment when I was trying to figure out which die or tap to use.  By the way, the 10s were used to hold stuff to the alu block and the Haines manual specified 12lb torque.  At 10 lbs the holes start to strip.  I had to tap to the next larger size on 3 or 4 holes  :'(  I couldn't find 11mm heads so I went to 1/4 in.  The next guy who works on the Porsche is going to have a head ache  :-*
