So there are umpty-odd flavors of nipples. My Pietta New Army revolver has one kind with a different thread, diameter, etc. than my Pedersoli Carleton Underhammer.
1) What is the taxonomy/classification system for nipples? What are the different types?
2) How would one determine what type a particular nipple is?
I would like to have some replacement nipples for my Pedersoli gun, but don't particularly want to wait 90-120 days and $$$$ for a special order from Pedersoli. However, Track-of-Wolf etc. stores offer a gazillion different types. How do I know which one is the right one?
The current Nipple:
- Overall Length: 0.493"
- Threaded end length: 0.212"
- Cap end ID: 0.100"
- Cap end OD: 0.148"
- OD, threaded end: 0.234"
- Thread pitch: 5 threads over 0.131" (peak-peak) or 4 over 0.116" (peak-trough) which equates to 34.48 - 38.16 TPI?
I tried testing the threaded end on "bolt finder" gage at local hardware store. Nothing seemed to fit exactly; but it was a close fit on either the metric M6? designation or SAE 8-32 designation? The gage was pretty chewed up though.
