Gunsmithing Parkerizing

[longbow62]

Is plugging the chamber and muzzle neccisary when Parkerizing a barreled action and stripped bolt? I have read some say yes, others no won't hurt a thing not to plug. Is it possible to ruin barrel?

I would recommend plugging the barrel, better safe than sorry.

Re: Parkerizing

Plugging the barrel is necessary or the phosphoric acid will etch your bore,the temps are low enough not to worry about pressure build up.

I always plug the bore before parking. I use silicon rubber tapered plugs available from Mc Master Carr. If I were parking barrels with chrome lined bores I would probably not worry as much but still plug them as well. I never really understood why some dont plug before parking it is a simple step and I plug em before I blast em anyway so I just leave the plugs in. For barrels with gas ports I just push the plug into the bore far enough to cover the gas port

Re: Parkerizing

Yes, plug the bore. Had a rifle ruined when the finisher didn't plug the bore. Extremely rough afterward. He tried to fix it by lapping the bore. Wound up with a loose, worn out barrel.
