Nipple for 2nd Generation Colt 1851 Navy

I've posted elsewhere...but will pass along my tip with washers...Bend a steel washer into a bit of a "V" shape then drop in the hole. You can custom fit the height by assembling the gun (with washer in place), & tap the muzzle lightly with a block of word until perfectly adjusted. You can continue to use with the washer in place, or use it's virtual height to establish the thickness needed for a permanent alteration. Many ways to skin the final solution. I have a total of 4-revolvers using a "V" washer (retained by heavy grease) to fit the assembly, & spent no more than 20 minutes total on all 4.

Not perfect, but it works.

A couple washers and some JB weld will go a long way towards a good fitting arbor .
Then you can fit the Wedge to push out with your thumb with out the gun beating the hell out of itself.
