Did a search and all that comes up are steel barrel results.
I have a couple of nicks I want to “dress up”.
Considering the brass screw method.
Hesitant to use valve grinding compound on brass.
Is 600 grit w/d paper better or ?
Any one done a brass barrel?
thanks!
Yes you can use the brass screw method on a brass barrel. It’s worked great on Benjamin barrels I’ve done. Just keep the RPMs and pressure low. Excessive heat and pressure could push a wire edge into the bore, leaving a burr. I keep the speed under 200rpms or so, and with the muzzle facing up, I limit the pressure to somewhere around 1 pound (less than the weight of the drill).
Lastly I recommend something less aggressive than valve compound on brass in particular. J-B Bore Compound is plenty.
Hi NT,
thank you for the advice! I’ll give a go.
Good luck with it!
BTW here's an example of a 397PA I did a few weeks ago. It was already dished pretty deep but there was no definition to the rifling and lands so I went until it looked crisp.
