    I am in the midst of a redesign for one of my guns, and need to add materiel to an aluminum receiver. I am wondering if Al brazing rod would be appropriate to build up and attach cast parts.
    Anyone have experience with this sort of thing? A backyard project for me, and I don't want to get involved with the legal complexities of manufacturing firearms...yet; so building up an existing gun works fine for me.

    Brazing is the metallurgical equivalent of glue. It doesn't bind to the parent metal very well at all. Build up is best done through the TIG welding process, with machining done after wards, and proper post heat treatment done to harden/normalize the metal.

    What exactly are you trying to do? A little more background info would let us help you better. We have a few 'smiths, machinists and welders running around the forum.

    Yeah, plus one there Matt, you nailed it. Adding material to Aluminum, especially in a receiver, is not my idea of a "simple backyard" project. It has the ability to go horribly awry if we are talking a serious rifle action or something of that nature....

    I've done buildup on high speed aluminum boat props before. It's nerve wracking to say the least.

    Calico modification

    I wouldn't dream of brazing a highly stressed part, just trying to add an additional mount point on my Calico. I want to run the scope mount ahead of its stock configuration, for better eye relief.

    Further clarification

    Since I can't edit anything in this thread, here is a picture of what I have done so far. The magazine is now the cheekpiece, but I want the scope mount moved forward a bit.

    Next generation will be a bullpup design, bringing the bore closer to sight line.

    Why not just make a new 1? Have it further forward than the 1 you have now.

    A new mount? Just as big a PITA.
    I'm just gonna have a custom rail done up to bolt on top of the mount. Something coming further forward, and about 1/2" higher. Bottom of the forward section may have a rail for light/laser.
    Of course, a Pepperball or Taser launcher could be a cool secondary :rolleyes:
    Something to fill the empty space would be good though, routing the trigger would be tricky. Gonna have to wait until I get to my in-law's shop.
