Well, the plot thickens. Took the gun up to JRH Advanced Gunsmithing, and Jack called me today.
First thing he said is my 1911 is now hard chromed, and ready.
Second was my Single Six would never shoot.
Here's what he came up with:
The barrel is good, at a pretty tight maybe .223, maybe .222 somewhere inbetween.
The cylinder is the problem. Instead of the fronts being in the same range, they are at .226". Can't add material to that.
So, a new cylinder is in order. Apparently the conversion is more popular then I thought:

100 bucks for a CNC produced drop in cylinder for a Single Six?
I'll be checking on this Monday. Anybody used one of their cylinders, or barrels?
Thank you for the comments.
Sincerely
P
