SharonAnne: you asked "Mikey, if I make a checklist of parts I want in my trigger/action group, and I install them, is that 'blueprinting' to your way of thinking?"
Yeah! Now ya got it! Grab yourself a beer! I'm a real basic guy - if the pin fits in the hole then it fits in the hole. 'Blueprinting' to me is exactly what you described: I make a list of the parts I want (if there are more than 3..), locate them in the 'parts' bin or buy them and install them (sometimes I might even polish a part, too).
Your process is much more detailed and phase specific to building a top level 1911 meant for competition. You accurately describe each phase and I find your postings educational and informative. I appreciate them and thank ya'll very much.
I do not machine frame parts or slides or design technical specifications to take a 1911 past combat functional, which for me with my 'olde aeyes' would include sights, trigger and hammer work/groups, grip style, accurizing or barrel work, and I have been known to use a Dremel tool to get things to, ummmm, fit. It works for me; by the time I'm through 'fixing' a perfectly good gun it will hammer the 10 ring all day long (usually with someone else shootin' it). It will print a cold first shot within 2-2.5" at 25m and I can print in the 4" circle at 50 with cold first shots. Competition guns shoot much better than that.
I have also been known to use the term 'thingy'.......It's something I do on occasion. Mikey.
