I thought this was a good one to bring up.

I got a 2nd cylinder (BP) for the 47 Walker. Always check for fit of this sort of thing and it does fit. Its longer than the original.

Is that normal, can you get one that is shorter?

I have been working on the arbor setup, current has .005 Headshake/forcing cone space. The new one is .0015.

I can contact supplier and try for another one, live with it, sand down the new one. I would like the thoughts on it.

Try using the new one with the .0015” clearance and you may be pleasantly surprised. If not, and assuming you do not have a lathe that you know how to use, find a ‘flat’ surface like a granite surface plate or even a piece of glass, and some 320 to 600 grit wet paper. Work the the front of the cylinder in a figure eight pattern on wet paper supported by the plate (or glass) with an even downward pressure until you have removed a few thousands off the cylinder face. Check often with an indicator while you are proceeding.

Just make sure before you start that the longer cylinder isn’t the better performer of the two.
 
If I shoot it then I am committed as they won't take it back.

I don't have a lath though a brother does, would have to check with him. I had thought about a fine grit in the belt sander though obviously that lacks precision that the wet sand paper and hand method would get.
 
I don't think you should take any metal off that cylinder at all, or send it back either. After shooting with it a few times the gap will probably open up to .003 - .004 anyway.
If it fits and turns good now, don't mess with it.

If your best solution for fitting is a belt sander, just send the cylinder back for an exchange. A DIY solution appears above your skill/confidence level, no insult intended.

Don't knock the belt sander for this job just yet. The secret is to unplug it before you start lol. It's just a few thousandths off the front of the cylinder.

I have done this with a Remington 1858. When my spare cylinder arrived, it was just a hair too long to fit in the frame.

I installed a fine grit belt on the table sander, unplugged it, set the cylinder down face first and did figure 8's with light pressure, rotating the cylinder every now and again, until it attained the clearance I was looking for.

Take it slow, check the fit often, and be sure to keep the contact square. Chamfer the chambers afterwards if it needs it. Reblue/Refinish if you like. Bridgeport not necessary.

BEFORE I DID ALL THAT THOUGH,

@Jim in Wisconsin brings up a great point about "break in".....If it's not binding up in cycling, put a few rounds through it and then measure it again.

So you're saying the new cylinder is .004" longer than the orig. and you have .0015" endshake with it?
If that's the case, I wouldn't shorten it to match the other one!! .005" endshake is rather big for the open-top platform, especially if you're going to shoot Heavy loads ( why wouldn't you??? It's a WALKER!! 😆).
Maybe save the too short one to fit in a Dragoon (loose the forcing cone bung) and have a "Magnum Dragoon" and get another new cylinder to match your longer one ( that fits much better!).
The .0015" may be good for a modern conversion cyl but it may be close for Italian cylinder runout. Make sure you polish the face of the cyl and the surface of the forcing cone bung since they are "bearing surfaces".

Am I wrong in that I thought the 47 Walker Cylinder was longer than the following Colts?

This is a BP cylinder - I keep the speed down as I believe that soft lead will scarped off if pushed.

My problem is at some point I am going to fine tune the arbor to right length. With a long cylinder and a short one, If I set the arbor length to the short one then enough difference that the long one will not turn.

I can see the paint aspect as well as a bit of wear in.

I can leave the arbor as is for now and and see how it goes, sadly range is close for another two weeks.

Mike: PM me with your choice of bullets in the unmentionable if you would as well as powder. I am shooting 45 LC (yea old school) in my unmentionable cylinder. The 47 Walker is mild shooting with all its weight.
