I started these instructions yesterday. Please start there, if you didn't.
When I clamped the jig into the vise, I noticed the guide's top lip overhung a bit, so I could not mill out the fire control area without running into the edges. After last time, I was nervous about removing too much plastic, so I have been going easy. My trigger components would not fit, so I needed to widen the hole.
I knew from my previous receiver that I didn't need to clear every cubic micrometer, so long as my trigger and hammer could move fluidly. Instead of milling the sides over and over, I thinned the plastic around the holes. Once the milling bit was straight with the trigger pin holes, I raised it slightly and took a bit off both sides. I repeated this process for the hammer pin holes, but I still needed to take out more and find a cleaner method. Fortunately, everything I've done so far has been erring on the side of caution.
The rest of the posts for this project have been arranged by date.

Another pass to widen the fire control cavity
