Sean noticed a picture I uploaded to the Toolmonger Flickr pool showing a sight aperture I made the other day. One of my hobbies is tinkering with airguns, so I often undertake little projects like this for my enjoyment.
First I turned a piece of 3/4″ diameter steel on my South Bend 10K lathe.
I drilled it for the aperture (it’s a .052″ diameter aperture), threaded it 7/32″-40 tpi to fit the Williams sight, and knurled the rim. This is why I posted a Dealmonger post about the 7/32″-40 die the other day.
I parted the aperture off the bar and moved it over to my Taig lathe, to bore out the recess in the face.
Finally, I finished it with some Oxpho cold blue so it wouldn’t be too shiny. (Here the flash makes it look shinier than it is.)
A fun little project that took only about an hour — I have full details up on my airgun tinkering blog, linked below.
