benny6I learned a new skill today. Invisible thread protector.
I'm building an M40A1 action for a customer. He asked for it to be bead blasted and black oxided as well as threaded with a discreet thread protector. It's all done and going out for black oxide tomorrow.
This was a neat project.

Lt CHEGBeautiful! I’ve got a PVA Osprey barrel done just like that and it’s so seamless that it just exudes quality and craftsmanship.

The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.” June 02, 2026, 03:05 AM
ibandaYes that fits the definition of discreet. Nice work!

David LeeVery nice benny but, you need to slow your feed rate turning as the tool marks are telling. If not an insert tool than its time to grind your cutter. Perhaps a rad at the nose and a finish cut.

SIGfourmeGood progression of skills on the lathe. Always need to have blue OR towels on the work bench.

It won't typically be an issue, but this barrel was a Bartlein M40A1 barrel. Frank at Bartlein told me they purposely made it with coarse machining marks to replicate some of the actual GI barrels that he evaluated personally.
I actually cut this with the compound by hand as I don't have the barrel taper attachment for my lathe, so I couldn't use the power feed function. I tried on earlier attempts to match the machinging marks, but turning the crank by hand was too inconsistent.
This is the only barrel I've ever worked on with aggressive machining like that. The bead blasting helps though. For all other barrels with fine machining, it should be completely concealed after bead blasting.
