You don't own a Machinery's Handbook?
Oddly enough many many Brits don't.
Serious question. Why?
Over here it's always been a very expensive book, …..<> 15 (maybe more) years ago my issue 27 was on special offer and still cost over £60 (say $80+) and since we went metric in the early 70's, shall we say MHB took a good while to catch up.
Prior to my buying #27, the only MHB I had dated from the late 30's early 40's,(it's not to hand) ………...and IIRC, I gave a retiring guy £3 or £4 for it in 1972 - ish, and considered I'd got a bargain! (that's £40 - £50 at todays money )
FYI Todays price in the UK on Amazon https://www.amazon.co.uk/Machinerys...coding=UTF8&psc=1&refRID=HD1550G8J0EJJR57C54M
Unless your customer's prints say otherwise, I would use tooling for the UN thread profile sized for 11TPI or 14TPI. The only thing special is that the size/pitch combination isn't standard. Thread form will be standard. Don't use UNJ thread profile unless the prints call for it.
Short version: yes, standard 60 degree tooling works.
Hi. Can anyone point me to a spec for the marine style UNS threads 1" 14TPI and 1-1/4" 11TPI please? Can existing 60 degree tooling make these - if so which (UNC etc.)? I'd ideally like to mill the threads. Thank you.
I just checked my version and it's 19! I got it with a buy out of a guy that was quitting in the mid to late 70's. Latest edition is 30 and it is around $105. They are expensive.
I'll see your 19th Edition, and raise you my 9th (1937)

Is $105 expensive? Compared to what?

It's a lot of money if A, you haven't got it to spare, and B, ''need'' it to earn a living.
I'd hate to be in the situation where $105 makes a difference as to how I live or earn a living .
Well;
It's as antiquated as can possibly be. 90% of it's contents are completely useless unless you're working with 100 year old equipment and building things to 100 year old standards and specifications.
It's practically useless if you work mainly to metric standards.
The parts of it that are actually useful (like op's query) are readily available elsewhere.
And like Sami said, it's bloody expensive.
Complete waste of money IMHO. My copy has not left the shelf for literally years.
Compared to for example the Engineers Black Book, which contains all the actually useful information contained in MH, including a lot of useful modern information that is not in MH, and was about £25 last time I bought one. I get a copy for everyone who comes to work here.

To a young machinist just starting out that is a lot of money. They would have think hard about buying something not used every day. As I gained experience I found it more useful.
You are truly full of shit! The MHB is one of the best machining references in existence. You are correct, it is also historical, but that is not a bad thing. It is updated regularly to include modern day subjects, processes and techniques as well as historical data. It is worth every penny of its cost. Further, it also comes in both paper and .PDF. The .PDF version is indexed, which is a great help in locating stuff. I use both. Please also keep in mind that it includes all the antiquated and current British standards as well. If you were truly "up to speed", you would realize that much of the Chinese products that have displaced American, European and British stuff and virtually all threaded items appear to use the British standards. The MHB is global reference. Spend some time and discover its contents. You won't regret it.
