Phosphating/Parkerising

When re-finishing a barrelled receiver is there a technique to phosphate/parkerize both the barrel and the receiver without affecting the bore?


Paul

All we ever did was to parkerize and then after the boil out and cold water, was to oil liberally and run a real good bore brush through the bore. As if to clean. It removed the crystaline formation on the surface and everything was well. We never had any problems.

Paul,

I played around with some test barrels and oiled the bore and used some those foam ear plugs to prevent excess solution getting in, worked fine and didn't pop out when the barrel was boiled.

Corks work well. Sears hardware has them in various sizes.

avoid corks...use rubber stoppers on the breach, and high temp silicone for the muzzle and then pick it out after your done, make sure you clean the bore well after your done. and run a oil patch afterwards..
been my experiance that real corks are a bear to get out they seal too good, lol.. rubber stoppers on both ends works ok, but they tend to pop out when you set them in a heated tank, air expands, and one pops out, usually the muzzle.

As someone who has no idea where to get corks or rubber plugs out here in the middle of Mauserland, but who has a drawful of foam earplugs, I find Bearclaw's suggestion brilliant!

Patrick, I placed the earplugs in after I boiled the barrel in water for a final degrease before putting it in the solution. As the barrel cooled caused a vacum and it seemed to hold them in place. But I like Chuck's idea. Maybe smear a bit of silicone on the earplugs.

Where to get the parkerizing stuff here in Mauserland?

I can't say Gunner, you may have to mix it yourself. I'm sure someone here has a recipe.

Thank you! Hope it has ingredients that are allowed to us to buy. But i hope ill get a recipe, thanks!
