    Default Spot weld crack

    Today while building I messed up slightly on a weld of the lower rail and burned through near the hammer pin hole, it is a small crack about 4mm long that extends upward from the hole. Anyone know a good fix for this, should I just try to weld the crack?

    Silver solder?

    Trying to picture the location of the crack.. If there is enough room, drill a 1/16 hole,at the tip of the crack, then weld it up. If you have a very fine lp gas tip, do and anneal on the weld. If not just grind the weld and keep an eye on it for awhile when shooting.

    I would go with welding, brazing or silver soldering. Either way keep a close eye on it for a while.

    If the receiver is out 4130, regular brazing is not a good idea. I would go with weld or silver solder.

    tig weld is the best method if you have access to one.

    Agreed TIG #1, MIG will also work.
    Back it up with some copper. Get yourself a piece of copper pipe from the hardware store. Cut a piece long enough to fit. Pound it flat with a hammer. Hold it on the back side of the receiver with a clamp.
    Clean the hole afterwards with a file or Dremel.

    thanks guys, a buddy of mine has all the supplies needed to do this right and hopefully enough talent also, but you're all definitely right, I gotta keep an eye on it. hope it holds...it was a damn good build up until that point
