Thank you sir! It was a pleasure to meet you and from what I can see so far your work is top notch. It feels 2389% better and locks up like a bank vault. I never would have believed it. I'm looking forward to seeing what you can do with the 3rd Model Dragoon (and hopefully the Paterson eventually).
Just so people have an idea of the work
@Jackrabbit1957 needed to do on the Walker (and this is likely not even a complete list):
Arbor corrected and cross pinned so it won't unscrew, barrel to cylinder gap set to .006, Cylinder face trued up, had about .008 run out. Rebuilt hammer safety notch, timing corrected
(I love how Jackrabbit1957 just glosses over this bit; this involved welding up the hand and re-fitting plus a bunch of other work LOL), action shield installed, Ruger type hand pushrod and spring installed, bolt guide fabricated and installed, arbor wedge slot fixed and fitted, wedge, hand and bolt guide case hardened, forcing cone reamed into breech end of barrel, music wire springs installed, removed the nipples and cleaned cylinder bores, installed new nipples with anti seize, checked cylinder to bore alignment, fitted new Uberti main spring
(ASM spring wouldn't interchange; original was broken and brazed together), sourcing and replacing a grip frame screw that was the wrong size and pitch, packed the guts with Mobil 1 grease, test fired.
The man is, as the French say, a true "artiste."
Hell of a nice guy, too.
