Uberti 1860 .45ACP conversion by Goons Gun Works

"Maybe sell it to them for parts and buy another, new revolver?"
I've been shooting handguns for over 70 years and have never sold or traded one. I see no reason to start now.
New 1860 Uberti arrived this morning. I've already converted it to .45acp.

I'd fix the short arbor before too much shooting of these "higher pressure" rounds . . . especially any +p's !! Definitely check to see if the arbor is loose . . . not "finger" loose . . . "chuck the arbor end in a vise and see if the frame moves" loose . Some are loose out of the box.
It's a great setup when set up correctly!!

I checked. It's tight.
Arbor length seems to be OK. With the two barrel lugs seated and wedge in place, there is about a thousanth of an inch clearance between the forcing cone and the cylinder face. Firing pin housing sits flush and parallel with the recoil shield. I haven't cut the loading gate relief yet, but I doubt that will take more than 30 minutes. It is a much better made gun than the old Centaur. No plan to shoot +P in either.
All that said, I need to refresh my memory on the Uberti short arbors and how to deal with them. I have three Ubertis and haven't had a problem with any of them so far - knock wood.
It'll be toward the end of next week before I have time to go out to the farm and fire it. I can't wait.

I hear ya and I'm not being a smart a$$ but it's an Uberti so the arbor is short ( ya can't tell by lookin). I understand your not going to shoot +p's but if weak loose powder and ball can beat them up, 21K psi ( normal 45acp) will do it a little quicker. Just trying to help and you seem to have the ability to correct it.

I've only done one and it probably took over an hour.

Right in the middle between Memphis and Nashville, along 64.
Ground the loading port into the Centaur this evening.
Also noticed the Uberti bolt is 5% thicker side to side than the Centaur bolt. That results in a bit of lateral slop when the Kirst .45acp Converter is on the Centaur. Gotta see if a Uberti bolt will fit the Centaur. Or alternativly figure out a way to broaden the Centaur bolt.

I've got a question about the Uberti short arbor fix.
It seems to me, the purpose of the fix is to create an interference fit between the arbor, barrel, and frame lugs to resist compressive loads.
Since firing the revolver creates tension and bending loads in the arbor and reduces compression between the arbor and barrel, what are the kinematics of the fix?
