Oh Bother 

How did Pietta sneak into this conversation??  We were discussing Uberti wern't we??  Just as a point, over the last 15 or so years, I haven't found enough error in the Barrel to Arbor fit in Pietta to be concerned about.

Regarding the 90 degree barrel twist, only enough offset is required to gauge the amount of overlap (should be zero).  The problem lies with the poor matchup between the bore in the Barrel Lug and the Arbor.  Mostly, out of the box, the barrel has had to be "driven" onto the arbor and the "driven" off to disassemble.  Just looking for a "witness mark" in the bottom of the hole will only confirm the whole assembly doesn't fit properly.

Now, to be honest. I can't speak for Uberti guns made over the last 4 or so years as I have taken down my shingle.  However, if Uberti couldn't be bothered to fix the problem over the last two or three DECADES I would not expect it to be corrected now.

I guess I did by mentioning that they HAD corrected the problem.
Uberti's are still  short ( that includes all the "factory Conversions").
 You're exactly right about the witness mark .  .  . if it ain't there, it don't fit right. Dressing down a spacer  "to fit" is quick an easy.  As I said, you can dress the wedge slot corners in the arbor for easier install / removal, being able to turn the barrel 90° or any degrees makes no sense and isn't necessary (caveat: for my correction. Maybe that'll make some folks feel better ). As I said before,  you don't need a measurement to hand fit a spacer. Too much changes when you drive the wedge in tight after all one's measuring. Fitting by hand with wedge driven in removes all "figuring" ( hard to measure  " wedge driven in"). Once barrel lug meets frame,  you can continue to dress the spacer (carefully) for "endshake spec." or affix the spacer in the hole and dress the end of the arbor for your "endshake spec". Simple and easy  and no unneeded removal of arbor diameter material.

To be honest, I'd never heard of the ninety degree thing.  I just rotate it enough for the barrel to be next to the frame so I can tell how much to add to the arbor.

Yeah, i think for that particular use, the scallops would be too much. There's already a lot going on there. It looks like the original is actually a wiggle. So I ordered one of those too.

Barry had said a few years ago that he was working on a Greek wave stamp but alas, I still don't see it.

I like to use the Brownells plug gauges to get the correct depth.  I don't have one for the .36 bore, though.  The one for .45's should work for percussion .44's since the bore size is the same.
