Rust Bluing on Welded/Soldiered Luger Parts

[Thor]

Yes, the premiere restorer, not me, does this regualarly, I would worry about too much heat warping surfaces and the heat treat aspect, on grip straps, this seem like the idea place to do this! I am sending Hugh Clark a pitted THROUGH Luger frame to experiment on! We will let you know how this experiment goes, Hugh just needs to learn what these other craftsman like Martz and Morgan have been doing for years! Thor
