Custom Chambering a Barrel by High Speed Shooting Solutions
As a “gunsmith” I find it entirely amusing how often customers believe that there is some real secret to what we do. Most of the time it’s simply knowledge, and more importantly, a confidence to work on a specific firearm. In fact, it’s amazing how often I get a firearm in that I do not know much about (especially old revolvers).
One of those common tasks is chambering a barrel, which actually is a relatively simple (yet time consuming) task of running a chamber reamer into the barrel. Re-chambering or chambering is a simple operation, mechanically speaking. One sets up a barrel in a low-speed lathe and using a piloted reamer (which is NEEDED, if one is not using a pilot, the chances for error are huge), slowly pushes the reamer into the barrel, making sure to clean out the “chips” or metal shavings.
Production barrel manufacturers will typically use a different process using a “roughing” reamer to get the general shape before using a final “finish” reamer to provide the final shape of the chamber. Further, they will use CNC machines to set depth accurate within a few tenths.

I have a barrel that I would like rechambered, but it cannot be put in a lathe. No joke, I have a Uberti reproduction of the Sharps Pepperbox.
Any suggestions how that can be done, or what/who to look for as a gunsmith to do it?
I'd like to have it rechambered to 22LR. Yes, I know that firing 22LR will damage the frame eventually, but I mainly want to so I can fire Aguila Colibri, and also "just because".

Shit, shouldn't have watched this. Now I'm going to start trying to chamber barrels, poorly.
