    Randy, you callin' me a hack?

    That's quite a setup for dressing those welds-- obviously you're a perfectionist!

    I dress my permanent welds. If I can, I put them up into the attachment so that I can just drill a hole through the side, install it, and plug weld from the barrel up flush and grind , file, and sand smooth.

    How many other gunsmiths do you know that dress their permanent attach welds with a surface grinder?

    Dang man... I usually just file them down, or if the weld is significant enough I turn it, then I blast the whole FH and re park. You my friend are the very definition of perfectionist.

    I used to rough grind and then finish by turning on the lathe.
    With the differences in hardness, you get that irregular finish while turning.
    Doing it on the surface grinder leaves me a perfect finish regardless of the hardness differences through the heat affected zone.
    Then I can nicely touchup blue the area I grind.

    I do get complaints about this once-in-a-while.
    The complaint is that people can't find the weld and want to make sure that I actually DID weld it.
    I just tell them to look at the inside of the blank firing adapter grooves and they will see the heat effected zone.
