Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

The older ones are more valuable to us with our simple manual machines. Mine is the 17th that I found at a thrift store. There are books written on how to access the wealth of knowledge.
I take that as a compliment.

Nice find. The bible is a great source of information, regardless of edition.

It's a very high compliment . Sorta like "you lucky b******".
And since I'm a non-technical-background, self-taught guy, I refer to it frequently.
"Machinery" was the name of a print magazine, that catered to Machine and Metalworking related shops. They saw a use for gathering together a lot of varied, and sometimes hard to find Data sets, as a valuable resource for Machinists as well as other trades. Thus it became "Machinery's" (it belonged and was produced by them) Handbook. It is not a Plural, of Machinery, rather the possessive form.
Great catch for a buck. I have VERY often told guys not to bother buying a current edition of MH, as pretty much anyone with a cell phone or computer access to the internet, is quite capable of finding all that data and more for free. Along with some specs that are not in MH at all, such as the specs for a UNJ thread, which we dealt with regularly in my last shop. FWIW, a UNJ thread uses most of the Unified National Geometry, but places a specified radius at the root of the thread, to add some to the strength. Not included in any of the Editions we ever saw!
I used to buy any copies I could find for under $20, and give them away to guys that seemed to have a need for one. I told all the guys that thought that they 'needed' one, that it was NOT a How-To book, rather a collection of wall charts that could cover a decent sized gymnasium's walls...
PERFECT explanation Trev! It actually makes sense now and it will never bother me again!
Thank you Sir!
I gotta wonder how many of the staff at Machinery Magazine laughed at the idea of people gagging on the name like I did?
An excellent description of the book's contents too!

I kinda doubt it crossed very many people's minds at the time. Machinery was a specialized, but fairly widely distributed source of information, news of what developments were taking place, in industry, changes in machines and tooling that were rampant in that era, etc. Pretty well known.
A quickie web search shows that they are apparently still publishing, or at least, someone has possibly picked up the name, as seems so common, or they may actually be the Historical successors still operating.... https://my.mydigitalpublication.co.uk/publication/?m=65921&l=1&p=1&view=issuelistBrowser&ver=html5

You can find all the old issues at archive.org.....for those of us that like to read old stuff like that, and find it interesting.

It wasn't the only handbook. American Machinsts' Handbook written by Calvin & Stanley and published by McGraw Hill was another one. Mine is the 1940 7th edition. It was recommended for shaper lore.
There are quite a few. At least with that one, old geezers like me are not left wondering whether the author and publisher spoke English.
In truth, I would posit, that the publishers thought that buying audience, only "barely" spoke English as they knew it. Being mostly Colonials or Rebels....
There were dozens or more different publishers pounding out books on different subjects at the time. Many crossed over from one area of expertise to others.
Kinda have to pick and choose as you filter through them...

I'm working on learning to thread on my lathe so I have to get some target numbers, though the numbers were the same, the formats weren't . I found the 1940 7th edition American Machinists' Handbook easier understand then my 1971 17th edition Machinery's Handbook. My 17th edition mentioned the newly agreed upon ISO threads. So I guess you want 17th and up editions. Neither had 1/4' x22tpi Whitworth which is what I was after . Blondihacks suggested the Engineer's Black Book for reference .
Threads are a review of what I learned 40 years ago. That once iron trap memory has sprung some pretty large leaks over the years. chuckle
