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.
It is placed in the vise against a stop and the hole for the base of the cartridge is machined as is the spring for the extractor.
Another view of the same operation.
Next an angle adapter is installed in the vise to allow the bolt fixture to set against it. This allow us to machine the opening for the extractor.
With this photo you can see the angle of the machined opening.
Close up as it sets in the machineCompleted bolts for this operation.
The last few to be completed today.
