I did up a few graphics awhile back to show how certain things function in 1911 pistols, and how certain modifications can cause troubles. Thought I'd post them here in case they might be of use as a reference item for folks who may be starting out building 1911s. These are not to-scale. They aren't intended to be. I exaggerated angles and other things to better show what I was gettin' at.
This one explains how a disconnector functions during the firing cycle.
And this one shows areas where folks commonly make mistakes when they're first startin' out.
