One more question please, you all helped me out with my Walker cylinder question, and I have one more question regarding my 1860 pietta sheriff model. After the conversation on the Walker, I checked the cylinder gap on my 1860, and a dollar bill will not fit between the cone and cylinder. I cut a thin shim from the top of a cat food can top, and now the wedge will not go all the way through. It might if I drove it with a hammer, but that doesn’t seem right. I don’t know how much of a thinner shim I can get. Any suggestions?
 
Doe's the barrel lug meet the lower frame firm with no gap? you may need a thinner shim. What is the barrel/cylinder gap? You really need a set of feeler gauges to properly determine the gap. Feeler gauges can bought at any auto parts place and most hardware stores. I would try some small washers first and see where the gap at both places come out to.

Pietta's arbors are already correct length.

In some cases Pietta arbors are too long. It's rare but it does happen. I find them easier to deal with than the short Uberti arbors.
 
I have a pietta1860 that I had to file the arbor down to fit a 45 colt cylinder on.
