Machinists handbook. It's a metal workers bible and a good reference for engineers. in fact, if you are in any way related to manufacturing (management, purchasing, planning) you should be familiar with at least some of the contents of this book.
also, kanabco and the virtual machine shop
Shigley's is great for learning how to design and why you design the way you do. It's the book I used in college and still reference at work. I'm not so sure it'd be great for a novice engineer. For a more practical approach, I'd recommend a few below (not necessarily in this order):
Machinery's Handbook. I'm an ME student and my dad's an ME. He gifted me this saying it was an important reference book and he was not wrong.
Machine Design by Norton
Theory of Machines and Mechanisms by Shigley
are considered the two bibles on machine design and are common in machine design courses.
Materials Selection in Mechanical Design by Ashby
The Machinery's Handbook is a must have and I assume you already know about this.
Mechanisms and Mechanical Designs Sourcebook is good to help spark ideas or solve problems. There are other books along the same lines.
There's information on tolerancing and machining in The Machinery's Handbook especially. I'm not sure on other resources for those. There are books on manufacturing processes that'll discuss the tolerances capable and design limitations.
NCEES Study Material
Roark's Formulas for Stress and Strain
"If engineering were easy, they would have sent a boy with a note."
Seriously there aren't any shortcuts. Either you learn the fundamentals or you don't. But if you want a really good general reference book, get The Mechanical Engineering Reference Manual
Other useful references:
You look in the Machinery's Handbook. Previous versions can be found.
You sir are a man in need of a Machinery's Handbook.
Check any bearings for slop. Threading would be a nightmare, but could likely be done seeing as how he has the gears for auto-feed. Harbor Freight's got this little guy
and get yourself a Machinery Handbook
The best thing I can recommend is Machinery's Handbook, which includes sections on practically everything you would need to reference when producing a first article. Important sections include Tooling, Machining, Manufacturing, and Fasteners. You can essentially use it as a primer on mechanical engineering.
What it does NOT include is stuff outside of mechanical engineering, which you will need to Google for yourself.
The Machinery's Handbook. A bit expensive but very practical. Older editions are cheaper and pretty much just as good.
I also like the idea of good quality safety glasses (ANSI Z87.x), but would recommend safety shoes over safety boots. If you are the type of engineer who is mostly at a desk and occasionally goes down to the shop floor, your feet will thank you. There are many kinds that are "office appropriate" but still have the full safety certification.
Its not all welding, but the machinest handbook is about the best refrence for everything mechanical you will run into.
Any edition would probably work for what you need. The newest looks to be this 29th edition, but I've got an older 24th that I've used in the past. Whatever you can find cheaper and better quality! If you can't find it at the library, i would seriously consider buying your own copy. For me, ever since getting into this trade, i cant seem to find enough time in the day to absorb (and retain!) all the information out there to improve my own ability around the shop!
What are you mostly running? manual machines or any CNC?

Finally picked up my copy today.
is it the Machinery's Handbook
> how much are they?
Yes, you could spend all 9k of that without even blinking. Whatever you spend, expect to double that cost with tooling and things to make your machine do all kinds of different work.
> what are the best manufactures
It's a bit of a mixed bag. If you're looking to buy new, your basic choices are new Asian import or old iron. Standard Modern is Canadian, Emco and Lion is European, and I believe Monarch and Hardringe still make lathes every now and then - all for between $16 and $80k, way out of your price range. CNC won't talk to you unless you're into the 5 digits either.
South Bend is made in Taiwan now, along with Grizzly, Precision Matthews, Baileigh, and others - mostly from the same factories with different paint jobs. They are pretty good machines and can get you started. But the other option is finding an old lathe on Craigslist or through an industrial dealer and getting that going again. A lot of them are still very precise machines that need a little TLC, and if you're diligent in your search, you could end up with an amazing machine for practically scrap metal prices.
> Is it possible to get it down a flight of stairs?
You can get anything down a flight of stairs, whether it's usable at the bottom is the harder question. Unless it's a hobby size lathe, you're not going to be carrying it down. They get really heavy very fast. But with proper precautions, ramps, levers, come-alongs, and chains, people have safely lowered machines weighing half a ton and more into their basements. How much of that you're willing to attempt is on you.
> how easy are they to use
I won't lie, there's a steep learning curve, and you'll never know everything. First step is to get [Machinery's Handbook] (http://www.amazon.com/Machinerys-Handbook-29th-Erik-Oberg/dp/083112900X/ref=sr_1_1?s=books&amp;ie=UTF8&amp;qid=1449544732), look it over, and as confusing as that thing is, it is commonly referred to as THE BIBLE. Otherwise, become a sponge and lurk forums, watch youtube videos, and read up.
If I were you, I'd get as much machine as you can afford, keeping one eye on the used market. Also, I'd look into getting a mill as well, then you'll be practically unstoppable in the shop.
Here's what you're looking for.
This site also has a lot of great info.
You look it up in a table. For example, tables of tolerances for shafts and holes for running fits, interference fits, press fits, et cetera, can be found a book like this.
Did you mean 'Machinist's handbook'? Also, if anyone of you are planning to give it a read, I believe there are legally gray copies that are significantly cheaper on sites like ebay. Cough cough.
one, talk to the machinists or the shops you plan to use, they can tell you a lot.
two, pickup a copy of the machinery handbook and a book on design for manufacturing
I don't know about a subreddit (and you shouldn't necessarily trust things that people write on the internet about machining) but this is a good place to start:
I saw it followed pretty religiously in aerospace and I'd guess that automotive does too, as I believe SAE was heavily involved with creating them (not positive though).
My current job (industrial components) uses them as a guide and reasonable starting point but is not bound to them.
Other companies I interned at just drilled to whatever size was available and hoped it worked.
It really depends on how critical the components are, how regulated the industry is, and how likely you are to get sued. If a component fails, "I followed best industry standard and practices" holds up a lot better in court than "I guessed and it seemed to work". There are a ton of other tolerance standards and about 1500 pages of Machinery's Handbook is largely devoted to them. It's worth browsing through some time, it's really mind blowing how standardized everything is. They seem simple but there are at least 100 pages devoted purely to dimensions on bolts.
Modelling the gears may be easier if you have the specification. Find a copy of (http://www.amazon.com/Machinerys-Handbook-29th-Erik-Oberg/dp/083112900X) and look in the section about gears for the spacing and angle of the gears. I own an old copy that stays on the shelf above my lathe- great reference for when I have to reproduce a broken part.
Although not used to structure my work, my most referenced book is machinery handbook
Machinery's Handbook, 29th https://www.amazon.com/dp/083112900X/ref=cm_sw_r_cp_api_fgaNxbR9QGJ6C
Other than that to be honest I just google, most times it's quicker. Of course trust but verify your source.
