    Laser welding/micro tig

    Hey I have a 22 barrel with some small chips in the bolt guide in the chamber.
    Firing pin was installed incorrectly.
    I either bore reserve it or I've been told it can be welded and I can dress it back.
    Anyone know who does it in Christchurch?

    What rifle? A lot of .22's are not intended to be disassembled, I may be reading this wrong but if you're saying it right the damage is in the chamber? I don't off hand know of anyone with the sort of gear to reach through the action to get into the chamber?

    Do you have a photo?

    I'd have to drag it out of the cabinet but I can take the barrel off.
    It's standard pinned and pressed so to speak. Haven't done it yet otherwise I know what I'm like and don't want another one in bits lol

    Bump
    Had one guy give me some helpful advice.
    Something rings a bell @gundoc might have suggested the tig welding back when I first identified the issue ages ago

    A delicate touch from a skilled Tig welder followed by some careful dressing with some good needle files. Just like marmite or mustard: too much spoils the flavour!

    @gundoc I can do the filing back but while I am OK on the tig I'm not sure I am that OK lol
    What's an appropriate filler wire

    Mild steel wire is fine. Almost all .22 rifles are made from mild or free-cutting steel. BSA's are 3% nickel steel but mild wire will still be fine for minor repairs. A delicate wee dot is all you need but a bit of practice on scrap first will be beneficial. I have done then with oxy-acetylene in the past with perfect results, but a fine flame and a delicate touch is needed. Tig is best.
