SHTF
Electronics Basic Tools
PART ONE: Small Hand Tools
After I wrote up the little
“SHTF Radio” article for wirecutter, I started to think a little bit further,
and started to think about how I could support other people who might have
electronics problems after the SHTF. I started to think about what’s in my
toolbox, and on my bench, sort of like the “What’s In YOUR Range Bag” articles that my fellow bloggers have posted.
Now, I’m sure most of you
reading this already have quite an assortment of tools. People like us, whether
we work on old cars, guns, airplanes, or just tinker around the house, have
tools. Lots of tools. My wife used to say TOO MANY tools until she saw me pull
some weird looking stuff out of one of my toll boxes, and fixed a problem on
her car in 15 minutes that the dealer wanted all day and $450 to fix.
After that episode, whenever
I say I’m buying another special tool for something, she just smiles.
A lot of the common tools
most of you have are “kinda sorta” suitable for electronics use, but buying
some specialized items will make your electronics hobby far more pleasurable,
and will surprisingly come in handy for a lot of other things, too.
I’ll start with small hand
tools first, and move on up to the more expensive, specialized stuff later.
As a general rule, I stay FAR
away from “pre-packaged electronics technician’s tool kits” sold by companies
like Jensen Tools and others. Over the years I’ve found their assortments to be
lacking in variety, they include tools you’ll rarely (if ever) use, the quality
questionable, and the prices outrageously high.
Build your own tool kit, one
piece at a time, and buy only the highest quality tools you can afford.
When I mention a specific
tool company, keep in mind that I get NO kickbacks, free tools, or other
inducements. I’m just recommending tool companies that I’ve used, and own,
tools from, and I’ve been doing this stuff for 50 years now. I know what works,
what breaks, and what you can get away with!
Gee, where have we heard
things like that before?
And BTW....sorry for the crappy formatting of the pictures, and their placement. This damn blogger interface won't let me size and place things where I want to!
Looks like I'll have to crack out the HTML books again, and start doing it that way.
I have a very nice Micro$oft Word document, but when I imported it, it dropped ALL the pictures.
Oh, well........

PLIERS
You need some GOOD QUALITY
long nose, or ‘needle nose’ pliers, about 4-1/2 to 6” long. There are many
different kinds (smooth jaw, chain nose, serrated jaw, end nipper, flat jaw,
curved jaw, etc), and the Xcelite catalog has SEVEN PAGES of long nose pliers!
The same applies to side
cutters. You NEED a good, sharp pair of them. If you do a lot of circuit board
work, get a pair of flush cut pliers. They clip the leads off right at the
solder joint, and don’t leave a sharp point of the cut off lead sticking up,
just waiting to snag your hands as you maneuver the board around on the bench.
The Xcelite catalog also has seven pages of side cutters.
For long nose pliers, I
prefer the Xcelite ELN54 thin long nose model, and for more delicate work, I
like their LN542 plier
ELN54 LN542
Get the “Cushion Grip”
handles if you can. Your hands will thank you!
For side cutters, I use the
MS549J flush cut with a small head for restricted spaces, and the MS54J for
general use. For cutting larger leads, I use the S54NS, which have a coil
spring to force them back open.
MS549J MS54J
Keep in mind that these small
pliers are NOT to be used for cutting, bending, or forming anything other than
soft copper wire! I loaned a pair to a guy at a job site once who brought them
back with a series of round dents in the jaws, complaining that they wouldn’t
cut anything. After I calmed down a bit that he’d ruined my $20 pliers, I asked
him what he was cutting, and he said “Wire, why?”. He showed me the “wire” he
was trying to cut, and it was copper-plated STEEL wire for his MiG welder. The
pliers looked like he’d tried to cut small screws with them, and they were
completely useless for their intended purpose. If you want to install Cotter
keys (“Split Pins”) in your car, use your big old honkin’ Craftsman pliers, NOT
your rather delicate Xcelite electronics pliers!

WIRE STRIPPERS
Please, don’t use your teeth
to strip wire on a regular basis! When I was 10 years old or so, I was having
my teeth cleaned, and the Dentist dug out a small piece of red plastic, and
wondered out loud what I’d been “eating”. I looked at the piece, and told him
it was from some small wire I had to strip, and his jaw about hit the floor.
Besides running the risk of a
self-extraction of your incisors, remember what Mom always said…”You don’t know
where that’s been!”, and keep your teeth for eating things.
While you can strip wire with your side cutters,
it takes skill and experience to do so, and you’ll wind up cutting the end off
a LOT of wire before you get the hang of it!
I have two different
strippers, for different sizes of wire. They’re not with me now, but one pair
will handle up to #10 wire, while the other pair goes down to #24. They overlap
a few sizes, but nobody makes a single pair that covers all the wire sizes I
work with, so I have two pair.
They look like this:
The pictured ones are made by
Klein Tools, whose catalog you can download from here:
You can also use one of the
“Automatic” wire strippers if you have the room to do so, and these are really
nice if you’re stripping a lot of wires, like to make a wire harness. You’ve
probably seen them, and they look like this:
These are made by Ideal
Industries, and go by the name of “Stripmaster”. I’ve been using these since my
high-school days in the 60’s, and if they’ve been around that long, they must
have something going for them!
Ideal is another fine tool
maker, and you can download their catalog here:
Snap Ring Pliers
You won’t need these very
often when working with electronics, but when you do, you’ll need them. Get a small
pair, with changeable tips, and you should be good to go. Most consumer
electronics uses “E-rings” or “C- clips”, but occasionally you’ll find small
snap rings used, especially in military equipment.
The dreaded “E-Ring” or “C-Clip”
I’ve never seen the two-piece
clip in the center, but I’ll bet it’s fun to remove/install. Most of the ones
you’ll find are similar to the two in the upper right of the picture. You can
pop them off using a small flat blade screw driver, and snap them back on with
some long nose pliers.
Be care, or they’ll go flying
across the room, leading to their other name, a “Jesus clip”!
That’s it for this chapter.
I’ll cover things like nut drivers, precision screwdrivers, hex keys, spline
keys, ball drivers, and other “drivers” in the next chapter.
