If peening would not get the amount of 'turn' required, would there be any use of the idea of skimming the shoulder enough to fit a shim or bushing ring in the gap? A ring has the advantage that it can be adjusted fairly simply on a lathe, while shim stock is easy enough to source in various thicknesses.
Thinking along the lines of the crush washers and such used to torque up against, and if a fella were to be able to work with a pretty close tolerance in mind, I'd figure that might be less work than a refit or set-back. There are punch jigs out there that will allow the workman to cut concentric circles out of thin shim stock, and I figure they would be a lot less intrusive than one stray hammer blow when peening, no?
Strictly theoretical on my part, but if ya started with steel shim stock you could pretty much sort out about how thick you needed, no? (Thread pitch, divided by the portion of a full turn required to have it torqued back into it's proper place).
Given that the rest of the slots, cuts, dovetails, etc., are actually where they belong, no? And that the headspace checks out.
Am I off base?
