I have a Remington New Model army revolver. The nipples were frozen in the original cylinder, so I bought a repro cylinder, It worked fine, but in cleaning it a nipple was lost. one of the reamining nipples threads into a 6mm nut, so I bought some 6x75 nipples at the Sportsmans warehouse. They don't fit at all. There are no markings on the cylinder. What other sizes are available. Oh, and I really hate the metric system.

Dixie has a site, may be info on there. if memory serves there are only 2 sizes for most C&P revolvers and a 3rd for Dragoons/Walkers.
Remember when your buying nipples for the revolvers, they do not use the normal rifle nipple.
The revolver nipples are much shorter and the outside diameter is a bit smaller .
Dixie's catalog shows a 5.5mm X .9 for the Uberti 1851, 1861 Navy, 1862 Police, 1849 Pocket, Baby Dragoon and Remington .36 and .44.
They also show a 6mm X .75 for most Italian Reproductions (including the Remington) except for the Dragoons and Walker.

My Remmy NA is a Pietta manufacture. It uses M6x0.75 thread nipples that are 0.632 inches long and take #10 caps.
There are three other sizes that might apply if the M6x0.75 won't work: M6x1.0, 12x28 and 1/4x28. However, I'd be surprised if it's really any of those.
I suggest you send one of the good nipples to Track of the Wolf[url] http://www.trackofthewolf.com...tableList.aspx?catID=14&subID=171&styleID=785[/url]
and see if they can help. They seem to have the biggest range of nipples.
Another option is Thunder Ridge [url] http://thunder-ridge-muzzleloading.com/nip_x_ref.htm[/url]
Good Luck.

I really doubt that the threads are SAE or UNS.
If you have access to a verner caliper or micrometer you could pull one of the good remaining nipples and measure the outside diameter of the thread.
A 5.5mm would measure .217, a 6mm would be .236, a #12 would be .216 and of course the 1/4 is .250.
With male threads, this is the maximum size and it could be as much as .007 undersize and still be within specs.
As you notice, there will be some overlap between the different sizes when the tolerance is taken into account.

I absolutely agree that SAE threads are unlikely, but stranger things have happened. Keep in mind that he has an aftermarket cylinder - AZC96: where did you get the new repro cylinder and who built it?.
Most of my C&B revolvers use M6x0.75. I do have two revolvers that use 1/4x28's (a Uberti 2nd Model Dragoon and a Colt Signature Third Model Dragoon), one that uses 12x28 (a Uberti Colt SAA) and one that uses a very strange nipple thread that measures 0.200 OD with 28 tpi (it's a Uberti 1862 Colt Police).
Nothing would surprise me.

"...I'm down here in Tucson."

Yup, I'm Up in Phoenix.
Interesting isn't it? It's always "down" in Tucson and Up in Phoenix, but Tucson is about 1000 feet higher than Phoenix. :hmm:

You might want to give the #12 x 28 thread nipples another look.
A class 2A spec. on a #12-28 thread shows a Major Diameter range of 0.2085” ”“ 0.2150”.
Your measurement of .212 fits kind of nicely, right in the middle of that. If I were you, I would go down to the local hardware store or Home Depo & buy a thread pitch gage. If a 28tpi gage fits those threads well, then I’d stay with the #12.

Actually, now that I’ve done a little more math, I see that a 0.9mm pitch = 28.2222222tpi.
M5.5 x 0.9 & 12-28 are probably so close that they can be considered the same thing.
You probably just need to pick which standard you want to cut the threads to when you are making the nipples depending on if you are working on a machine that has a metric gearbox or a SAE gearbox.
