Things have been a bit slow at work, so I was able to do a bit more on the project.
The trigger and sear pivots are 1/8" stainless shoulder screws.
Still need to radius the edges and buff the frame.
The Frame has a trigger pull adjuster built in. It also has a small recess notched into both sides to accommodate the breech/tube/frame clamps. More pics of those when I make them.
More to come.
