Hole filling opinions please

[ICANHITHIMMAN]

Hello friends

Please offer your opinion on filling these holes. There are 4 of them in the rear receiver bridge. Two are blind and two are through and through.

The action is a pre war model 70. It lost its collector value when the previous owner drilled these holes.

Option 1. Peen and file down some screws and cold blue.

Option 2. Silver solder screws in place followed by dressing them down and ceracoat.

Option 3. Tig them in place and dress them down and blue.

The finish on the action is in remarkable condition. I know in the hot tank would rule out the solder.

weld and ceracote not sure if filler rod will blue the same as the action. chamfer the holes and fill from the bottom up don't just bridge the holes. the two that are through and through use a brass backer inside the action to block holes so you can fill from the bottom up. the weld wont stick to the brass and the brass will also act as a heat sink.

If I tig it I'm either using a hanger as filler wire or the brownells wire. Thank you for your reply.

Good evening and hope that you and your family are doing well. Also Happy Easter "Christ is Rissen".

If you have a good Tig machine and a good Tig welder go for that option. Watch what metal filler you use so you can Cold Blue.
Otherwise I would use option #1. Put some long set screws in and make sure that they don't go into the Bolt. Cut off the excess on the top of the Receiver and then carefully "Peen" and file down, the Emory fine cloth to finish and Cold Blue.

Option # 3
You can put a set screw into the holes, cut the slot off and then Peen and Tig over. No need for filler rod and hole already filled. You can PM me and then we can talk and can give you some ideas.

If you are going to Cerakote it you can make it look like "NEW" with any of the three processes. Just before Cerakote - Sand, Polish. Bead Blast.
You can make it look like NIB. Good luck and let us know when finished.

I use a MIG (no TIG, maybe someday I'll be motivated to learn), easy to zap the holes and file flush. Seems everyone has forgotten that MIG welders still exist...and much easier to use especially on simple steel jobs like this.

I've also simply used JB Weld to fill them. Since you're Cerakoting, this is easy-peasy. Because the epoxy has different surface texture you can "see" where the holes have been filled if you look hard enough- but in your case, shouldn't be a big deal

Yes another option, put a set screw in with JB Weld and Sand Down then bead blast and Cerakote. Never see where the holes were!

Find someone that can run a tig and you're golden, it's an easy fix, tig with cold paste to block the heat, then to the 3M Scotch-Brite wheel and it's as good as new. Good luck... Cheers

I can tig. I used to weld for a living. I'm just concerned over the heat. Mig is not appropriate for this. I really appreciate all the input

You shouldn't have any problem by using a good heat paste on the receiver, putting in filler screws halfway down the holes, and using the proper filler rod... tig away, step on the power slowly and start your filling puddle...
Good luck... Cheers

MIG is just fine for this. The HAZ is minimal- and the back of the receiver is irrelevant when it comes to hardness/temper.
I've welded up these holes with a MIG and put my finger right next to the weld after.

Not much different than pin and welding a muzzle device on a 14.5" barrel. Pin it and Tig would be my method. Dress it down and finish it with a spray finish. Never know it was ever there.

I got the screws in after degreasing and cleaning. I will add photos of the during and after when I have a chance to weld it up.
