I'm in the process of building an AR15 that's going to be a little out of the ordinary. However, since what I'm planning is not exactly "off the shelf" I need the help of someone, preferably someone within 1.5 hour driving radius of the Philadelphia area, who has the skills of a machinist/welder. It's small thing, basically I have a small part with a hole of approximately 0.06-0.08" in diameter that I need filled/welded closed. The part is stainless steel (not sure the grade/type) and I believe it is heat treated (not sure if that matters). Any ideas out there?
