Sandblasting The Action and Barrel

I am wanting to duracoat my new savage 12 .204 and was a little concerned with a few areas.

First of all I will disassemble the bold and the trigger group assembly from the action so I will be left with just the barrel attached to the action.

My main questions are:

1. What do should I plug the end of the barrel with so the rifling and inside of the barrel wont get touched with the media?

2. Is it ok if the crown of the barrel is blasted and duracoated over?

3. Obviously I don't want the chamber to get blasted, what can i use to keep it from being blasted?

Thanks
 
Use a Foam ear plug for the end of the barrel and it wont hurt anything to blast/duracoat the crown! stuff the chamber/action with paper towels or rags.
 
I roll up a piece of paper and put In in the action from the Rae like the bolt goes in and just fill the whole raceway for the bolt to run. I take a bullet and tap it into the end of the barrel to plug the bore. The ear plug idea sounds good though
 
When I had the DuraCoat bead blasted off of my .204, I plugged the muzzle with a small piece of aluminum rod that was wrapped with duct tape and I packed the receiver/chamber with a wad of modeling clay that I picked up in the hobby section at Wally World...

I stripped the lower receiver of the butt stock and trigger group, but left all other parts intact..



After the bead blasting, I soaked the parts in a tray full of air agitated mineral oil to work loose any grains of the media and then gave the whole thing a bath of sprayed on alcohol to remove the mineral oil and any media that may be being held to the surface by the oil...

After the weapon was dry, I sprayed it again with a can of Auto Prep to insure that all the oil residue was gone and primed it with a self etching primer..



After that, I painted it as I wanted and it's holding up well...

I wonder when the last post you had was actually on topic and pertinent, not just a trollish jest...


The ear plug works well for the muzzle end. I have chamber plugs for cleaning, those would be great in the chamber its self. I would then use shop rags for the rest of the action would be fine. Just take your time and dont allow the mwdia to build up. And, obviously, a thorough cleaning after is a must.
 
Do you feel better now Shane? How many rifles have you actually sand blasted? What Media did you use? Furthermore, other than using an earplug for Paint, how well will n earplug hold up against 135 psi or so while sand blasting? Im sure that your Personal experience will help the OP. Please chime in.
 
2 bbl/actions. I roll 2 ear plus together for the muzzle. The ear plugs hold up fine, because one doesnt blast the ear plug directly. It just catches any 'overspray'. And I have done plenty of blasting in my day. Thanks for your concern.

OP, I like the 60-80 grit Alum Oxide for firearm catings. It's not as rough as say, an SPS type finish, IME. You can play with them between coats. I have also seen a guy use flame cut decal material to add 'ghost' flames to a bbl/action. He went over the whole thing with the 60, then applied the decal, then hit the rest with 80. It looked pretty cool when done.

I am considering a soda blaster for my house. Then I dont have to got to the autoshop to blast!
 
You can plug the muzzle with anything, I polish the muzzle on my rifles so they clean easier and just cover that end of the barrel with a piece of masking tape. For the action like was said, just stuff it with small rags and and tape off what you dont want blasted. I also prefer 90PSI with glass bead over sand or silica, it leaves a nice soft muted finish and looks great with stainless. I would assume it would also work well for painted finishes also.
