Machinery’s Handbook-29th Edition of the Machinist’s Bible

Posted on by

Authoritative. Comprehensive. Invaluable. Practical. Updated.

Updated?

29th Edition of Machinery's Handbook now available.

I have relied on my 20th Edition copy since I entered the metalworking industry as a supervisor in the early 1980’s. It has served me well through the years, and while respectfully used, is showing evidence of ‘serious use’- missing thumb tabs, dust jacket in tatters, a host of bookmarks…

Here are 5 reasons why I’ll probably upgrade to the new 29th Edition:

  • New sections added on Micromachining, Statistics, and Calculating Thread Dimensions;
  • Expanded Metric content. The jobs we see in our shops today are increasingly metric as we serve a growing global market;
  • Easier to use- they have added tables of contents at the beginning of each section;
  • Extensive revisions to key sections including Mathematics, Gaging and  Dimensioning,  and Machining Operations
  • It has been re-typeset (including tables and equations) and many figures redrawn.

Now the problem for me is choice: Do I get the ‘regular edition’ to replace augment my current 20th edition handbook? Do I jump into the electronic age with the CD version? Or do I acknowledge I no longer have the eyes of a younger man and buy the “larger print” edition?

It’s time for me to buy. My investment in the 20th Edition sure paid off. How about you?

Which  would you  choose? What other books have you found critical to your practice in our precision metalworking field?

Machinery’s Handbook 29th Edition can be purchased direct from Industrial Press.

Athlete, Engineer, Physician, Machinist- What Are The Chances?

Posted on by

The odds are pretty slim you’ll make it into professional athletics.Time spent on math and science can assure you of a well paying professional career, even if you choose not to go to college.

Machinists make the bone screws that engineers designed that physician surgeons install in injured professional athletes.

 
Professional Athletes:  16,500 positions; Average Salary $79,460;  source BLS 2008 http://www.bls.gov/k12/sports02.htm
Professional Engineers: 1,600,000 positions; Average Salary $79,000  (my quick estimate from a look at the table) http://www.bls.gov/oco/ocos027.htm
You have a roughly the same chance to make the same wages by choosing engineer or athlete, the number of potential positions improves dramatically for engineers.
Physicians and Surgeons: 661,400 positions; Average Salary $186,044 source BLS 2008 http://www.bls.gov/oco/ocos074.htm
Machinists: 380,720 positions; Average annual earnings $38,940, (Aerospace machinists $43,110)    http://www.bls.gov/oes/current/oes514041.htm
I compile employment and compensation data for the PMPA, and the BLS machinist data seems to understate the wages of top performers.
And the BLS data seems to indicate straight time only. (Not include overtime.)
Yes maybe some day I will pay $50 a ticket to watch you play your sport.
But based on the number of positions, chances are I’m going to pay a heck of a lot more for your professional work product if you become an engineer, a physician, or a machinist.
If you can do the math, you can see how these odds work for you.
