Now to get the rear sight working...
Here's my initial drawing...my only change was to go with a smaller radius on the top.
I punched out the pin.
I did not lose the spring.
I milled a channel in a 14"x1/4"x1/2" piece of plastic. I'm not sure what type of plastic it is, probably UHMW. It is very slippery. So I had to take lots of light cuts.
I rummaged around in my tooling and found this tiny woodruff keyseat cutter, which worked fine for making the undercut slot.
Fits perfectly!
Then I milled some ears on the underside.
And used a 90 deg. vee cutter to make them into wedges. These mate with the vee cuts in the sight.
A small radius relief...
I was going to cut the serrations on the mill but decided it would be safer (slippery plastic...) to use a checkering file.
Not perfect but it looks fine.
Installed and works fine.
Here are some of the tiny cutters I have...
