Does anybody know of a website or other online source for schematic drawings or other depictions of 1911 parts which gives the exact measurements and cut angle for each part? I have tried the in-house search engines of several 1911 and general handgun sites as well as Googling every possible relevant word combination I can think of, but no joy. Any help would be muchly appreciated.

I have never seen the detailed drawings for the specs. In 1911's and AR-15's, Companies use to advertise that they were "Mil-Spec", the problem they didn't say which military. For specs on 1911's go with Colt specs or somebody like Wilson. Many lesser brand guns are whatever they can find that works! After WW II Argentina bought 55 gallon drums of Remington parts for their 1927 version of the 1911, and those are very good guns.... until they ran out of surplus parts and made their own! Ivan

Kuhnhausens books The colt .45 automatic&The Shop manual for 1911 will list all the specs for the 1911.These should be a must for any 1911 owner

I use Kuhnhausens 1911 shop manual and his DVD. I also have the Wilson combat DVD and the AGI DVD also.

I got tired of buying new 1911's that had problems and decided to learn everything about how to repair, trouble shoot, tweet them, do frame up builds. It was time to stop the insanity of losing $$.

My first build was a Chinese norinco 1911 after replacing the barrel with a surplus USGI $59 barrel and IAI national match barrel bushing. With me doing all the fitting she now shoots cloverleafs and clusters at 25yards. No matter who shoots it, it's that good. I installed a adjustable trigger, FLGR KIT with the 18lb recoil spring.
She's a low budget build using very affordable new parts. She a low budget race 1911.

For my very first build I wanted to test my talents and new knowledge to see how good a low budget build could be accurate wise. I fitted the barrel bushing for a 100% lock up yet allowing the barrel to go from full battery hinging down to load the next round with no barrel spring in full battery or when it's lowered yet my goal was to have a 100% lockup in full battery. I did check the lug engagement and the push down test to make sure the link used is the proper length.

Now this accuracy was with the Russian wolf ammo and I didn't tighten up the slide to frame fit. I just focused on fitting the new barrel and NM bushing. I did remove the machining marks on the feed ramp. The feed ramp on any 1911 should be polished. I also added a ramp for the disconnector. If you run the slide by hand at a certain point you feel a bump when the disconnection hits the slide. By filing a ramp very carefully the bump is removed.

We ran 500rds through this 1911 flawlessly with no changes in accuracy.

You can learn from books and DVD's. I'm no gun Smith but I have built machines that manufacture everything. I was a car, truck and 4x4 mechanic in my early days. Before I retired I was a lead tech in an engineering r&D lab.

My point is there's nothing we can't do if we apply ourselves.

My next build will be a frame up build with all new parts.

Thanks to all who replied and a Happy New Year to all fellow forum members. Shame on me, guys: I had forgotten all about the superb Kunhausen books on the venerable 1911. I appreciate the reminder; they proved to be just what I needed.
Meanwhile, I just was gifted elsewhere with a link to a full set of digitally remastered blueprints used by contract manufacturers to turn out M1911A1 .45 pistols in 1942. I'd like to share it here for the benefit of any of you who may find it useful or just interesting from an history perspective.
