[QUOTE=shovelwrench;139374227] Then finish the muzzle/crown and the barrel is done except for attaching a front sight and addressing the sight rib/flat/grooves(terminology??)!!


Congrats on the barrel; beautiful machining!

Most refer to those grooves in the rib as striations or serrations. No doubt the factory has a specialized milling cutter to do them. Likely an expensive custom cutter and not worth the cost for a one time job.

I have never cut new striations except on front sight bases and other small parts. But I have cleaned them up for a re-blue with a 40 LPI checkering file.

On the cyl hand, the old timers would "stretch" a worn hand.
With a guide clamped to the work to keep the file straight, the checkering tool might do a fine job.
