Thanks guys.
"More info"
Gtrgy888, if you want to use brass, it's your choice but also, it may be easier to "work" and, when you get what you want , you can make a steel copy. Personally, I would never use brass in mine or a customers revolver. Anyway, another way to do this (and a little quicker) is to get your single spacer "close" but on the generous side ( + .003 or .004") and then you can dress the arbor end down to get your bbl/cyl clearance "number" ( I like .0025" - .003"). I'm just used to doing it that way. THE PROBLEM doing it that way is any time you remove material from the arbor end, the wedge slot gets slightly wider. I compensate for that with an "adjustable wedge bearing" (flat ended 1/4 X 28 set screw) installed in the end of the arbor (through to the wedge slot! It's a "WEDGE bearing " !! Lots of folks miss that) . Not only does it restore the full use of the factory wedge, it allows the owner to adjust the depth of the wedge install . . . in case of re-holstering problems (CAS). It's never bad to have options
So, there ya go . . .
