Cimarron Uberti R/M Type II Arbor Question

[45 Dragoon]

I hear ya and thumbs are probably good enough with cowboy loads.
I've noticed the "endshake" measurement changes from "thumbs" only to a "smack" with a machinist hammer. No need to remove the barrel unless you're cleaning .  .  .  (probably have one then)
Endshake on my acp's is less than .002", can't get that number with just thumbs.

Just got my gun back from Alan Harton of Single Action Services in Houston Texas. No more arbor problem here ! He welded metal to the front of the arbor and fitted it to the barrel hole . Would like to show pics but ain't smart enough to put em on here .
