Gunsmithing parking raw chrome moly action

[radmcg]

I have never had a problem parking a raw SS action and barrel but I was looking at a 591 surgeon and noticed they are chrome moly steel shipped in the white. When I called Steven at Surgeon he said no problem ceracoat directly onto the chrome moly just like SS. Do you guys park chrome moly before ceracoat or just spray the ceracoat onto the raw chrome moly just like ss?

i know dick about steel.....but me thinks there is lots of chrome moly that will not take a park job.......so


you bead blast the item in question and paint the shit out of it cook it, assemble it and shoot the thing to destruction.....

I only use Molyresin, can't say for the other coatings. My personal preference is to Parkerize CroMo before coating. The only reason is it gives an added layer of protection with areas that get scuffed or abraded & helps hide some of wear. Some coating mfrs advise against Parkerizing, in my experience I haven't seen any benefits or negatives.

You should try a coating called melonite or tennifer. I have the details on a individual who will coat bolts for $15 each and barrels for $70 handguns $75 shot gun barrels $45 with no min charge. 7 day turn around. This is the same as on the sw mp pistols or xd. but under a different name Isonite.

SS generally doesn't take Parking, blasted CM will, never tried without blasting first. You should blast anything before spraying, the finish will be shiny if you don't and the rough finish gives it something to hold to. Melonite is a form of heat treating that just happens to leave a black finish (semi-shiny). I would recommend to anyone that wants a flat finish on the parts to blast them first. I have parked parts before putting a KG Gunkote finish on and I can't say it makes any differance.

Melonite/Isonite/Salt bath nitriding has been discussed in a number of threads here and is really not the best finish for an action. As I recall, Surgeon and/or others specifically say not to salt bath nitride the action or bolt.

Surgeon specifically indicated to my 'smith that doing so would void the warranty on my RSR.

The temp on Melonite can relieve stresses...may get some warping.

Re: parking raw chrome moly action

I have yet to see barrels warp after being melonited. It acctually increases barrel life, makes the barrel rust preventive, corrosion resistant, and also increases lubricity in your bolts and actions. I know a person that does it cheap, and will also do a great job of it.

Re: parking raw chrome moly action

I see thousands of barrels ran through the a parkerizing process, have yet to see any problems with the process the customers always seem satisfied, smith and wesson and glock use the melonite/isonite/parkerizing process!!

Usually it just has to be bare metal and grease/oil free. This is correct.

Re: parking raw chrome moly action

There is a huge disparity in pro's and con's with finish usually landing on someones's favorite. Parkerizing is usually done by filling the bore with water and plugging is so as not to fill the rifling with coral. Look at it under a microscope thats what it looks like(great for accuracy?) Melanite or tennifer are very hard and near indestructible, wouldn't recommend on a rifle barrel hard and shiny black is good. High temperature stress, ruining heat treat and changing of bore lubicity not so good.

As far as duracoat, ceracoat, or similar paints,carefully clean and degrease the metal. Plug the bore, and sand blast it rough on the outside. The finishes all bond well if properly applied and can be easily touched up if scratched. And again not enough heat to cause barrel or action problems.

Re: parking raw chrome moly action

once again like i have said i see thousands of barrels ran through a melonite/tennifer process and there is no problems with any of the barrels. Actually people are very pleased with the process. People asking left and right about getting their barrels and gun components done..
