Tig welding Sako bolt handle
Anybody with actual experience welding a 60's era Sako bolt handle- what filler rod to do build up work. Just altering the bolt profile. Also, does anyone know of a threaded heat sink for the same bolt- L579. Thanks.
This is how I do it on a L461, vee the joins out and weld down the sides and around the back using a high quality mild steel TIG filler rod. I try not to do any build up with the TIG. I don't use a heat sink as I keep the heat to a minimum , but you could just turn one up out of ally or copper.
Hope this helps.

Dans40XCFiller wire-
Match the parent material.
If coated wire is used...remove the copper for color match.

setters5Tell us about that fixture please.
It's just a block of ally with a slot milled in it, and a piece of timber with a flat plate bolted on to push the handle up tight. Agricultural I know.
I originally made it for mausers but have built a better one for them, this one just gets used for odd ball jobs.
The Sako bolt is smaller in diameter hence the cardboard spacers! Improvisation rules.
Dan, That is part of the issue. I have not tried to contact Sako but what is the handle made of; appears forged. I have some of the 5% nickel you get from Brownells, what I have always used, cleaned of the copper coating.
Kda, I've never used it but have heard Brownells 5% nickel rod is crap for TIG.
I use ER70S-6, the bolt handles I use are 1020.
Are you just going to build up the existing handle to change the profile?
Yes Metal that is the plan. If I can use any mild steel 70K tig rod I am good to go. I believe I have some ER70S. I have done the same to pre64 Winchesters with build up to look like pre war bolts- makes a much nicer looking handle. I would love to do what you did but no jig and then the machining. I have nothing but time, files and stones.

Can we see a few photos of the mauser one and some photos of completed bolt jobs on mausers
