Just thought I would drop a note in to tell John that I just used his blue prints! I have a DWM I swapped a buddy for that I am rebuilding. I needed the complete firing pin assy (pin spring and guide), a complete side plate, and trigger and spring as well as the main toggle pin to pin the toggle assy to the upper, as the Germans call it the der starke verbindungsbolzen
Unfortunately some fine person who had possession of her in the past had beat the ever loving snot out of her and rolled a burr over into the ID, sorry Inside Diameter I forgot I am not at work. If that were not abuse enough someone did the worst job of nickel plating I have ever seen, there must have been .002 of nickel on her in places AND under that was copper, why I have no clue, I guess they thought the nickel needed primer. After spending 3 days in the Brownell's nickel striper and 2 days in ammonia and hydrogen peroxide, both of these operations should have taken a couple of hours at most, there is still residual plating in the hole.
Anyway this is all to say, when the pin did not enter the hole and I saw the problem; I checked Johns wonderfully clean drawings to discover the diameter should be 7.2mm +.02mm/-.00mm with a pin diameter of 7.18mm +.00mm/-.05mm.
I just got off MSC's website and ordered a reamer in 7.02, by Wednesday that little problem will be solved!
Thanks John
