Work is progressing on the VG1-5. This post is about threading the barrel for the gas piston. In our last post about the barrel we had turn the out side dimensions and cut them for length. http://gunlab.net/vg1-5-update-barrels/
This post is the manual lathe work to do the threading.
Another step toward the final product being completed.
Are the barrels already chambered?
No that is the next task then flutting
Chrome plating gas sealing rings could be beneficial…
Inside of the gas piston also.
Although that would be, in some sense, an overengineering this design and purpose, since they are not made to shoot tens of thousands of rounds with no cleaning…
