The Instant Engineer Kit

"You have to be born to it." That's what my supervisor said about our types of jobs. This was after I related an incident that had occurred a few weeks earlier.

I was in a manufacturing facility (a regular occurrence in my position) when the plant manager came into the office to review my work. When I opened my computer, he looked at my desktop wallpaper with one eyebrow raised, so I explained that it was from the Atwater Kent radio factory during the 1920s. He looked at me with a somewhat bemused expression and said "You know, most people have pictures of family or vacations on their desktop, not a factory from the 1920s."

Skipping ahead to when my supervisor first saw the photo, he glanced at the picture then looked back again with the slight grin that he always has when his curiosity has been aroused. I told him about the plant manager, and he replied "You have to be born to it."

I don't know if I believe that, but I suspect there is a grain of truth to it. I didn't have much exposure to industrial environments when I was young. I did, however, have plenty of exposure to machinery, even if most of it was made more than a few decades before I was. So maybe there is a reason why I enjoy the kinds of things I work on.

Enjoying my job is a big part of being able to do it well, or at least I think it is. But that's not to say that there aren't things that can help you be an effective engineer.

Recently True Blue Sam introduced me to his "ACME Instant Forester Kit" It's a compilation of the data and tools that are needed to generate a forest management plan. Of course, you should have at least a basic understanding of what you're doing before the kit will do you much good, but if you have some basic knowledge, it has pretty much everything you need.

Inspired by this kit I've decided to put together a list of the essential tools that I use for my job.

Presenting the ACME Instant Mechanical Engineer kit.

Information (or more precisely, correct information) is your biggest ally on the job. That is why the first two items on my list are books.

The Machinery's Handbook:

If you ever set foot in a machine shop or draft a single mechanical drawing, you should have this book, as it is full of every type of design related information imaginable. I have the 26th edition, which is relatively recent, but I have a certain fondness for older, well worn copies. They feel like old bibles when you hold them, and fittingly so as such books have guided machinists and engineers for generations.

Of course, if you don't like carrying around a book the size of an unabridged dictionary (or have a problem with small print) you can always get the CD version and read this book straight from your computer.

Gieck's Engineering Formulas:

The Machinery's Handbook's theory based cousin is a much more portable, if somewhat less practical, resource. Geick's Engineering Formulas has been around for more than 30 years, but is something of a recent discovery for me. If I were a little more paranoid I might think that knowledge of this book was intentionally withheld. Why? Because for about $35 this book gives you all of the formulas that I have in about $700 worth of college text books. Admittedly, there is not much of an explanation for most the formulas, but I was still awed by the fact that most of my 4 years of college (OK 5 but who's counting?) could be condensed into one little book. Even better, every other page is blank so after you derive more useful or specific versions of a formula you have plenty of room to add it to the book.

Also in the photo above you'll notice the next item on the list.

Mechanical pencil:

This may seem silly, but I actually do consider this important. Back in college I always used plain old #2 pencils. I felt no shame in picking these up from the classroom floors in the evenings so I rarely had to pay for writing utensils. They were great for scantron style test forms (where you have to fill in the bubbles) because you could use a blunt tip and get nice even coverage. They worked well for written exams too , with the exception that they often blunted too quickly. You could see this in my exams as the writing would start out with nice even lines and then slowly decline into broad graphite swaths. Then I would have to get out my pocketknife (occasionally frightening TAs who led overly sheltered lives) and touch up the pencil. The cycle usually repeated several times an hour.

I will sharpen no more!

A 0,5mm mechanical pencil provides a consistent, thin line that is perfect for doing sketches. Better still, there's no time wasted touching up the tip on your pencil (which is important when you're transcribing data in a hurry.) Of course you better remember to carry extra graphite or you'll be in a real bind, because it's often hard to find the 0,5mm in many storerooms.

What good is a pencil with nothing to write in?

The log book:

If you're trying to look important or you're filling out forms on the go, a clipboard may be more your speed, but sooner or later most engineers are going to need an actual book to keep track of their information.

It used to be common to take these to a notary at the end of each day or week and have each page stamped to certify that you had generated the ideas on the date shown. Now that we have so much electronic communication, there are plenty of timestamped records to document what we say and do. Still, the log book is indispensable for keeping track of your actions in the field or your experiment, because if you're working around heavy machinery or in dirty environments, you just can't walk around with a computer.

I should note, however, that when you work in a manufacturing environment it's best to make sure your log book has a few battle scars. Walking into a machine shop with a pristine logbook is like showing up in a white shirt and kakis. You'll look like you never do any work. Cuts, grease stains, and smudged fingerprints are all appropriate methods for breaking in your log book.

The calculator:

I have yet to meet an engineer that does not rely on a calculator at least part of the time. Since the introduction of the first electronic pocket calculators in 1970, scientists and engineers alike have been relying upon them to process data more quickly and efficiently. Of course there are always concerns about computational errors, but these are possible with mental and manual calculations too. With today's reliable electronics, the only likely cause for calculation error is G.I.G.O.

Powerful graphing calculators are increasingly common even among high school students. They are probably overkill for most people, but having a programmable, equation graphing, formula storing, and upgradable calculator comes in handy when you're having to do some mental and mathematical thinking.

Personally I like my HP 48GX. I've had it for more than 10 years, and it has served me well despite an occasional ding or dent in the case. What's special about this calculator is that it's designed to work primarily in Reverse Polish Notation (RPN)

What? you've never heard of it? Most people haven't, and most people won't believe me when I say that it's just as easy to use as a standard calculator. In fact, I find that it's even easier to program.

Still, some people can't get used to using a calculator without an = key so I carry around a backup calculator which I frequently lend to people who can't figure out how to use the good one.

The catalog:

And I do mean THE catalog.
If you haven't seen the McMaster Carr catalog then you need to go here immediately. This catalog has everything but the kitchen sink. Wait, never mind, those are on page 1965.

The only problem I have with this catalog is that it makes it too easy to become a catalog engineer. There is a solution to most of your engineering problems in this book and it is much too easy to get in the habit of opening the catalog every time you are looking for a gadget to fix one of your problems. Still, it's a very handy thing to have on the shelf.

The multitool:

If you carry a toolbox anyway, you don't need one of these. (Though I'd be willing to bet that you have one anyway.) Multitools, be they Swiss Army knives, Leatherman tools, or some similar knockoff product are an important tool for everyday life, but I've found that they are equally important as a tool for engineers.

They aren't really suited to heavy work, but they will occasionally save you from taking the time to find a screwdriver or a set of pliers. They're also very good for what I consider to be 'parlor tricks' in which you run across an unusual problem and solve it with only what you have in your pockets. (Hopefully an appreciative audience will be present.) This sort of thing doesn't really reflect upon your ability of an engineer, but it can do wonders for your reputation among mechanics who think engineers can't turn a wrench or less creative individuals that don't like to get their hands dirty.

And with that we move on the the last (and perhaps somewhat facetious) item on the list.

The coffee mug:

I cannot sing enough praises of this little device. Whether it is a travel mug, demitasse, insulated mug, tall mug, short mug, or plain old standard issue ceramic model it is something no engineer should be without. It helps me wake up in the morning, it can carry a cheerful (or pithy) message, it provides refreshment, and an excuse to get up for a walk to the coffee pot (or to the porcelain one.) In case you don't read binary code, it says 'OHM' I usually use an insulated mug with the company logo on it because it keeps the coffee warm through entire meetings or late into the afternoon when everyone else has stopped drinking coffee and the pot has been turned off.

Of course, I am almost never without the typical ceramic mug. It's a nice, simple, functional design. Plus, it serves a vital purpose! It leaves a very specific kind of stain on your engineering drawings. How else are you going to convince people that you stayed up all night working on them?!

Bonus item: The portable planner. [+/-]

I needed a way to plan my daily tasks, keep track of things on my to do list, store useful contact information, hold business cards, keep receipts, plan trips and record my daily activities. Oh and all of this needs to fit in my back pocket, or else I won't be able to keep it with me when I need it. As usual, I put together my own solution to this problem.

The leather cover is from an At-A-Glance calender, with an elastic band added to hold it closed when it's not in use. Inside I've added my own favorite calender (cut down to fit neatly inside.) The back of the calender has room for post its and miscellaneous information. Phone numbers and other contact information are written inside the front cover. A clear plastic sleeve (like you use for a passport) is stapled to the calender's cover. That's where I keep my to-do list. A scratch pad sits in the pocket on the left, I use it to plan my day's activities. The receipts and business cards go in the pocket behind the scratch pad. This thing even holds a pen.

Generally when I need to do something, it goes on the to do list. When appropriate I transfer it to my daily list on the left and scratch it off of the original list. At the end of the day I tear off the daily list and either move things to the next day or log them in my calender. It has the advantage of not only keeping track of the work I have to do, but allowing me to track of the tasks I've performed on any given day. You wouldn't believe how often it comes in handy, and as far as I'm concerned, this is more effective than a pda or smart phone, because I never have to charge it (though I do occasionally get new pen cartridges)
