Phil:
The pin is an easy lathe turn. The screw is a Brit thread. It can't be cut on US tooling. My recco is to phone Kirk Merrington: 830-367-2937. It will be done right. |

It is not a British thread - it was made in America over a hundred years ago and was cut to a currently obsolete thread size. Dave Suponski can probably tell you the thread size.

With all due respect, if the gun is question was made by Charles Lancaster of Drury Lane, London, the firearm in reference is not "made in America." And unless Mr. Romig has more experience with British double guns than I -- which may indeed be possible -- I am willing to bet that the thread spec of the screw is of British spec. At least originally. It may have been since altered by someone. Then again, I may not know what I'm talking about... Thus, I respectfully withdraw from this thread.

'scuse me Mr. Rise - I forgot myself and thought the thread was about a Parker.... My mistake and My Apology.
Looking back at the leading post, I wonder how I could have been so blind... |

I am sure that Brian or Kirk can produce whatever you want , but you might want to consider Tom Carter , I know he makes screws and firing pins for Parkers.----843-546-0609

Can't be done? Any good tool room lathe, such as a Hardinge or 10" South Bend with a change box can cut as few as 32 different pitches, from 4 TPI to 224 TPI. My Galicop (South Bend, Belgium) can cut 96 different pitches. New machines can cut whatever the programer tells them to cut.
As for profile, that's what tool grinders do when they are looking as those big ole optical comparators. A common lathe in the UK is a Myford, and they use south bend gears in many of their smaller machines. Having foundries and machine shops both here and in the UK, I kinda got an idea what they can do (Especially when they loose their "Not Invented Here" attitude). |

Edgar: Yesir, this is America and we Americans can do anything we set out minds to. I am not a machinist but turn out some decent replacements for clocks and guns on a simple mini lathe. It may take me 3-4 days off and on to do what a machinist can do in in 1-hour. I may also have to make a jig or machine some sacrificial pieces to obtain the final results but it can be done. Having said that, I would be able to stay in business about 15 minutes producing machined products. The gentlemen mentioned by Mr. Campbell is probably one of many that can perform this service. The question is who is qualified, willing (not me) and how much. Bob
