OT: Spot bluing question

[J Miller]

Since every gunsmith I've dealt with and talked to has chickened out about welding up the four extra holes in the receiver on the MR-7, I've devised a plan of action that will render the extraneous holes all but invisible.

What I'm going to do is order in some extra long ½" scope base screws and then glue them in the holes using the LOCTITE Black Max adhesive.
Then I'll cut them off just above the surface of the receiver and very carefully file them down to flush with my jewelers files and polish them with 600 wet or dry soaked in oil.

If I am successful I will have four small white dots to blue.

What or whose bluing product would be the best for this?

Joe,

I don't know what to use for the bluing but I remember seeing instructions on doing what you are thinking about. I remember that they cut them proud of the surface and then carefully peened them with a ball peen hammer before the file was used. Don't know if this is better; just letting you know.

Bob,
That is part of it, I just forgot to type it in. I talked to a gunsmith in Nebraska, I think, who said the exact same thing.

It should work. I've seen refinished Military rifles that had holes filled in that manner and the holes were barely visible.

Hi Joe:

I've had the best luck with Brownell's Oxpho Blue in the cream formula. Its "thicker-er" than liquid, so it clings to curved surfaces -- like we find on guns -- very well. I always degrease the metal parts with Naptha (lighter fluid) and heat them up with a heat gun, or place them close to a light bulb. A few applications help to darker them up, and lightly polishing them with the Oxpho Blue and 000 steel wool helps the color "take" too.

I have a partially used bottle here, as I just got a new bottle to replace it. If you want it, just PM me your mailing address and I'll send it along.

Tight groups.

IME degreasing and warmer than average temps help a lot with all the cold bluing solutions and Oxpho is the best.

[J Miller]

Old No7,
PM on the way to you.

I've never used the Oxpho Blue in any form. I have a bottle of Birchwood Caseys gel blue that works OK but not great.
And I do degrease and add heat, I found that works better as well.

Thanks for the info and help, now I got to get those long screws ordered.

For Spot Bluing it's hard to beat the Birchwood Casey "Presto" gun bluing pen.

I got mine at the local 5&Dime and it worked quite well to blue the crown of my chopped Mosin.

"Old No7, PM on the way to you."

Got it Joe, it's all packed up and will go out either tomorrow or Saturday.

Good luck!

I'd forgotten about them things. You used to see them in every gun shop, but no so much any more.
