Quickly learn how to barrel seat your 80% 1911 build.
It was difficult to see where exactly was the middle, so I Dykem-ed and used the calipers to cut a middle line on the flat area.
I got a good first hole.
But after unsuccessfully trying to mill using the drill press (it walks A LOT), I decided to just go to touching holes. This is the not very clean final product.
After some filing and sandpaper, it looks a lot better. The barrel sits fine too. I’ll file some more afterwards.
Keep the jig on and we’ll finish the frame with the hammer & sear pin holes next.
