Working on the VG1-5 bolt

The last post on the bolt was when we completed the lathe work on it. This left us with a turned bolt with the firing pin hole drilled and bored.




A fixture was designed to allow us to machine the bolt at the different angles and still keep everything aligned as it should be.
