Nice, but will bluing look the same? I had the receiver (drilled holes) on a Model 70 welded up like that, then blued. You could without a doubt tell holes had previously been drilled because the character of the blue was different at the weld spots.
Here is a barrel before and after. I wish I had taken time to do better photos. The blue came out with no trace of repair. I think the welding on metal with higher carbon content with higher power can cause a concentration carbon around the puddle that shows up in the blueing.
Are there any impacts to the strength of barrels caused by welding the pits? I wonder if Sherman Bell could be convinced to perform some destructive testing?
Both repairs look great but I have an amature question. Were the barrels done for purely cosmetic reasons and if so could the barrels have been filed down to remove the pits or would that thin the barrels to an unsafe thickness?
