Machining a standard Remington 700 recoil lug with our newly created jig for oversized blueprinting.
Some folks were asking how this is used, so here's a quick demonstration.
The lug is installed in the jig "roughly" center. The jig is then mounted in a 4 jaw chuck and centered in, as one would with any other round part.
The small "step" in the back is to ensure 100% contact at the barrel shoulder, eliminating any possible radius interference at the shoulder junction.
This particular lug was opened up to 1.100" to ensure plenty of room for the accurized receiver threads. It will then be hand-stoned for flatness parallel.
