Hoping someone can help me with this request. I need to know the dimensions (thread sizes and TPI) of all the machine style screws on the 2nd model Maynard (minus the rear sight screw). Many thanks, Kurt

I'll see you this weekend Kurt and we can have a cold one and I'll tell you everything I know about Maynard screws. It might not take long or we might need a second cold one if we get sidetracked.
It's a deal! I'm also bringing some very nice bourbon!!!
Hi Kurt ---
I don't want to steal my friend's thunder, so you'll need to wait a day or two until you see John . . . .
I know John won't mind if I give you a early preview / hint on the rest of the story that friend John will be telling you. I think John bills his time at $150. per hour plus travel expenses, so hopefully this will save you some coins.
In 19th Century American industry, there was not a standardized thread/tap specification attributable to American engineering; but rather, the American firearms producing companies, for the most part, either copied or imported the British standardized mechanical thread attachments, which were patented by Whitworth, and known as, what else but, Whitworth threads. In 1834, Sir Joseph Whitworth took out his first British patent for his screw machine. In 1841, Whitworth published a paper addressing the universal system of screw threads.
John will give you the particulars from there, such as the mean angle of degrees and the number of threads per inch for specific diameters..
If you two start with the Bourbon and have some free time, John may even tell you about his great, great, grandfather, Captain Bly, and that's a story well worth hearing.
Gentlemen enjoy,
Webb

Webb, thanks for the information, I had no clue of the use of british standards. I've known John for a few years now and enjoy siphoning off as much of his knowledge as I can. I slightly remember something about how John was instrumental in the shortening of his name from Bligh to Bly. I'll ask for a repeat of that story after a few rounds of hooch!
Kurt
Back from the Nats, thanks again for your help John. Kurt
