I sure appreciate all your input. It's not what I was hoping for, but better to be disappointed here where it doesn't cost money.

Jon, I can't sue the guy. He's a likeable old fart and has done me a few good turns. He meant well and I prolly should've trusted my gut and stopped him.

I hoped it might be possible to lay it on ice or something and weld a line without heating the receiver too much...

i can understand trusting someone like that. i did a similar with my beloved 458winmag and scope bases.

i dabble welding with making bbq pits. what welding does is melt steel so it pools and mixes with the weld rod/wire. no ammount of ice is going to offset the heat damage that the reciever will suffer. it doesnt take much heat to turn a reciever from a rifle to a bomb.

a welding arc is about 6500F the temp of the sun is 10000F on the surface. welding gets pretty hot.

i am always amazed at how fast it can heat a block of steel to burn through gloves while the part is held in pliers...

im not saying it cant be done but the weld and grind to fit is going to cost more than a new reciever.

I think the "right" approach is to machine out the rail, and silver solder in a replacement. This keeps the temp down, so you don't muck up the receiver.

I know a welder I would trust to do it. He is one in a million though. Not many are that good. Put it this way, you trusted a gunsmith and he screwed it up. How many welders are you willing to let attempt it?

Tig welding would be your best bet if your going to try welding it and it can't be done all at once. There is no arc splatter and your welder needs to do it in spots. What I'm saying is if it takes the whole day,then so be it. Spot weld in an area then move to the opposite end and do a spot weld then let it cool all the way off before doing it again. Then a couple of more spots in completely different areas and so on and so on. This will help prevent warping and pulling of the steel. Just hope the nozzle of the Tig gun will fit in were you need it. You can do body work with a tig with minimal warping and thats running a bead it's your coolest cleanest welding form.

Part of my job involves TIG welding. Under NO circumstances is this a job for MIG welding. And, JonM pretty much has it right, IMHO. So not worth the effort, get a new receiver. It'll be ridiculously hard to find a guy who WILL do it, and most of those guys probably COULDN'T do it. (Want it screwed up more?)

Does the receiver function properly? Is it "Ugly"'? Is the tampering obvious when assembled? Is it still strong enough to do it's job? If so, maybe you should just leave it alone. Or if not, I'd ask the old fart to split the cost of a new receiver with you.

How about some photos?

Yeah, some photos would help immensely.

Find someone that can TIG weld and do it well , Look at some of their work because I know alot of people that can TIG weld but their work isnt what I would call quality work. I had one guy " he is retired and out of the business now " that I had TIG stuff for me and if I told him to make it look like the rest of the factory welds , thats what it looked like when he was done. Wish he hadnt retired and sold off all his equipment because I have a couple other projects I could have used him for
TIG welding is a art as far as I'm concerned . Some people do it well , others are just plain artists with their work

Anyway, I'd like to get those feed rails welded and then stoned/ground back flush and smooth. The rails were left so rough I can see wee bits of brass under the feed rails.

We have a huge shortage of gunsmiths in Alberta.

Can a good welder do this? What should be done to prevent heating/warping the action? What's the process - MIG, TIG or ?

Any help here would sure be appreciated, 'specially from someone that's had welding like this done.

thanks.
Show pics of what you need done, place a scale next to said item. Will work from there............The only thing I can't weld is a broken heart, that is another catergory.......

I might have line on a fussy guy and will show him the work next week. If he says he can do it and I get a good feeling, I will post "before" and "after" pictures.
