2020-10-20 (Tu) 80PercentArRifle

I made another pass with the milling bit to get the fire control cavity wide enough. The narrow sides finally accepted the trigger. Even though the bottom of this hole was thin, the surface where the spring rested seemed strong enough while I pulled the trigger a couple of times.

Now that the functional parts were complete, I spent time cleaning up little cosmetic things like mold lines, sharp corners, and rough edges. Most of the time, all I needed was the back end of a razor blade, so if you look at the picture below, I move the knife away from the camera.
Cleaning up the edges

I didn't do anything about the thin plastic between the trigger and gun, but it didn't seem necessary. If this impairs the gun's operation, I will have to reinforce the receiver with a metal plate or epoxy.
