45 acp Cylinder issues neep some help

[jpickar]

I have a 45 acp cylinfer a friend let me take home and see if it would fit my New Model Blackhawk. This is what I have found and think the cylinder will not work but want some ideas here before I return it. He is giving me a fair deal on it.

-The rachet is .002 taller than mine and therefore the cylinder is very tight. I could fix that. I have a lathe.
-There is almost no measurable barrel/cylinder gap. This could be fixed by trimming the ratchet .002".
-The front of the cylinder where the pin goes is .015 too short. I could fix that. I could make a bushing to fix that.

BUT here is the weird thing. When I put a 45 acp brass in the cyliner and index it. The head space is .012 to .013"! I have about .004 on the 45 colt cylinder when measured. I do not know how to fix that! Moon or half moon clips aren't needed for the single action. And would be a big pain to use.

Any opinions and help is welcome. The cylinder has some rust spots on it, but the inside is in very good condition. The timing is good too. Here is a pic of it with a brass in it. Showing rust spots. The brass is at the long end of spec for length. Is $40 to much?

Thanks in adavnce, John

bottom line it is the wrong cylinder, most likely an old model, thus the gas seal ( stub) up front is too short?? yes with enough "work" you could rebuilt it completely and possibly make it work, seen that done by guys who just LOVE a challenge, and have the time , know how or the money..........

as well as from the picture, it sure needs a little 'TLC' in the refinish department, lots of pitting.............

OK, well that explains why all the "just off" demensions. It just never occured to me that it was an old model cylinder.

I could shoot AR ammo in it. But I have a S&W 625 in 45 acp and it shoot real good.
Well, maybe I'll just pass on this one and give it back to him.

Thanks, John

You can't shoot .45AR without some mods. I'd bet that you can't get .45AR brass to seat and let the cylinder rotate - unless the cylinder has been modified already.

PM sent about the cylinder. I have a project I could use it for.
