I had planned to work on the gun drilling set-up over the Christmas break, but the hydraulic pump that I ordered didn't show up on time (it arrived today). Instead, I made a few engineering changes to the tang sight design and finished it up, made the detail drawings and started making it.

The sight is my own design, based on the best features of various sights I found on the internet. It is a flip up design with detents in the up and down position, has a windage adjustment via a thumbwheel, a sliding center to set the elevation and a turn of the peep sight locks everything in position.



The first part in the cue was the locknut/windage adjustment. It is a simple block with a notch for the windage thumbwheel and a 1/4-36 tapped hole for the peep sight to screw into. I needed to make it first so I could use it as a thread gauge for the matching 1/4-36 thread on the peep sight.

Next in line was the peep sight itself. The the back side of the hood and the threaded shaft was turned first, then it was parted off and held in a collet to turn the cup shaped bore typical to these sights and knurl the outside.





Next comes the sliding mechanism, windage thumbwheel and the frame to hold it all.
