OCTK Lite part 2
Buying good hand tools isn’t as easy as it used to be. Not that many years ago, if you wanted top-quality stuff you bought American-made brands—Snap-on or Mac if you had the money, Sears Craftsman if not. Done. (If you were British you bought Britool; if French, Facom; if Italian, USAG: and if Australian; Sidchrome.)
Now it’s not so simple. Not only is there a bewildering array of brands available, manufacturing is now global. No longer does brand loyalty or even knowing the country of origin necessarily guarantee quality. Most Craftsman tools are currently manufactured in Taiwan, and it isn’t even Sears any more. Tool behemoth Stanley/Black&Decker now owns the Craftsman line, and Mac and Proto as well, plus the (formerly) British Britool, the (formerly) French Facom, the (formerly) Italian USAG, and the (formerly) Australian Sidchrome. Sheesh.
You can’t just go by materials and manufacturing process. Socket sets from $19.95 Harbor Freight specials on up to apparently identical boutique assortments costing ten times as much advertise chrome vanadium steel and forged construction. There’s simply no way for a consumer to determine the actual composition or quality of the alloy.
You might think you could at least trust the guarantee, but I’m not so sure. A chain auto-parts-store Torx bit I bought out of immediate necessity recently was made in China and has a lifetime replacement warranty. But is that because the tool is of such high quality that the company has confidence it will never fail, or because it is so cheap to manufacture that the company can afford to replace bits for the few people who actually stress and break them? I strongly suspect the latter. Sure, you’ll get a new tool free, but if it breaks when you’re attempting a repair 20 miles down a dirt track and 150 miles from the nearest outlet, that’s not of much immediate value.
You can of course still guarantee superior quality by sticking to the ultra-premium makers such as Snap-on or Mac. Otherwise, I’ve gone back to a rather old-fashioned approach to estimating quality in a tool: I handle it and inspect it. That might seem flippant, but really, your eyes and hands can tell you a lot about a tool—particularly in the finish. As an example I give you the Britool SAE/metric ratchet and socket set I bought years ago. It was actually manufactured in Taiwan, but the quality was excellent. The finish was a perfectly even satin, absolutely consistent from socket to ratchet to extension. The roll markings on the sockets were crisp, as was the knurling on the extensions. The ratchet had a 72-tooth head, this requiring less swing to engage when working in tight quarters than one with fewer teeth. The extensions had hex fitting so you could apply a wrench if for some reason you couldn’t get the ratchet on it.
A superb set of tools—and if I’d known then what I know now I would have bought ten of them, because soon Britool changed all their sets to blue-boxed “Expert” stuff that was a steep plunge off a cliff in quality. Thick, uneven chrome and much simplified accessories, clearly now built to a price rather than a standard. Can one help suspecting the same cost-control measures were applied where it isn’t as obvious?
On the other hand, consider the 1/4-inch ratchet I picked up at a Napa Auto Parts the other day. It’s the chain’s own brand, Carlyle, aimed, they say, at professional mechanics. Manufactured in Taiwan, each piece carries a lifetime guarantee (although, importantly, I understand you must show the original receipt, unlike the similar guarantee offered by Snap-on, Mac, and even Craftsman).
Ignoring for the moment the de rigueur Snap-on-esque handle shape also ripped off by a zillion other brands, consider that the Carlyle ratchet retails for 18 dollars, while the U.S.-made Snap-on item above it goes for a nickel less than a hundred. To be accurate, note that the Snap-on ratchet has a quick-release button; the equivalent Carlyle ratchet (which the store did not have on hand) lists for $25. So let’s call the Carlyle one quarter the price.
In terms of finish, I could see absolutely no difference between the two. Both are fully polished, and the chrome is even and betrays no machining marks. The head on the Carlyle is actually a bit lower-profile than the Snap-on item, but that might be due to the lack of a quick-release mechanism. Each is rebuildable; Carlyle lists the kit number right on the ratchet.
So far the decision of which to choose seems easy. However, differences become obvious with manipulation. First, the Carlyle ratchet has a 60-tooth head—not bad, but the Snap-on has 72, again, less swing in those tight spots. And Snap-on’s “Dual-80” head technology is known for its immense strength. Nod to Snap-on. Next, the reversing lever, which on the Carlyle is flat, sharp-edged, and rather stiff to operate, while the Snap-on’s rounded lever flicks back and forth effortlessly. Also, the Carlyle’s lever rocks a bit when moved, indicating looser tolerances, while the Snap-on lever simply pivots. Another nod to Snap-on.
With the faceplate off each tool, the differences become more stark. Note, first, the significantly larger diameter of the anvil gear on the Snap-on (bottom here); then the dual drive pawls versus the single Carlyle piece. I’m not about to test a $100 tool to failure, but I’d be happy to bet someone more than that that the Snap-on would take far more torque before it failed. Even the lubrication was a contrast: The Carlyle seemed to have been anointed with a few drops of oil; the Snap-on was liberally infused with a light grease.
So there is little doubt the Snap-on ratchet is functionally superior to the Carlyle, and certainly far more durable. The question is, is it four times better? I think the answer to that depends on your own situation and attitude. First, let’s be blunt: At least $25 of the extra price of the Snap-on is in that name and the status of those high-profile trucks. (I dream of winning a contest: Five minutes inside the truck; anything I can throw out in that time I get to keep.) But another $25 probably represents the extra cost of producing the tool in the U.S. Still, we’re left with a disparity. The Carlyle definitely offers a lot for the price.
If I were a professional mechanic there’d be no hesitation, but I’m not, and I’m also not rich, so it’s more complicated. However, I still trust my Prime Directive for a field tool kit:
If you’ve brought out the tool kit far from home, something has already gone wrong. Why risk compounding the problem by using cheap tools to try to fix it?
My approach to adhering to this axiom on a less-then-unlimited budget is two-fold, as I’ve written before:
First: Spend the most on the most critical tools, the ones you’ll need for the most critical repairs, then economize on the rest. Top of the list is your ratchet and socket set.
Second: eBay. I’ve haunted online auctions and snagged excellent deals, especially on sets missing one or two items, which I then shop for individually. Your local Craigslist can also be a good source. Since premium tools are the most durable, buying used is generally safe unless they have been seriously abused.
Thus, the first items I chose for the One-Case Tool Kit Lite were the 1/4-inch Snap-on ratchet dissected here, and its big brother, a flex-head Snap-on FRLF80 3/8ths ratchet. I have sockets and extensions from the same company for each; however, I’m investigating some alternatives as less-expensive options.
Two kits that will (almost) breakdown-proof your vehicle
Our modern four-wheel-drive vehicles, virtually without exception, are far, far better machines than those we traveled with 30 or 40 years ago, the rose-tinted recollections of some of us nothwithstanding. (See here for a direct comparison.) Yes, they are vastly more complex: The average car today has between 25 and 50 electronic control units or ECUs (the Bentley Bentayga has 90)—some linked, some independent—controlling everything from shock absorber adjustment to accident-avoidance braking. But those complex systems have brought us more power, better fuel economy, a huge improvement in safety, and cleaner air—all at once.
Despite this complexity, vehicles in general are more reliable than ever. Solid-state ECUs are incredibly stable and durable; precision design and manufacturing processes and advances in metallurgy have made engines and other drivetrain components much longer-lasting. A car with 100,000 miles on the odometer used to be noteworthy; these days, beater pizza-delivery Civics with 200,000-plus under their faded paint are as common as Domino’s outlets. When something does go wrong, the car will quite likely be able to tell the mechanic what is is. How long will it be before a car can sense a part about to fail, then automatically log onto Amazon and have the piece waiting at the shop when the self-drive function reroutes you there?
These advances have made overland travel easier and safer as well, even if—to be fair to those rose-tinted recollections—if something does go wrong in the bush you won’t be regapping the points with a matchbook cover if the dwell shifts, or disassembling the carburetor and popping in a rebuild kit if a gasket goes bad. (But since we no longer have points or carburetors . . .)
One thing has not changed, and that is the two types of problems behind the vast majority of issues in the backcountry that bring a vehicle to a halt: tire punctures and dead batteries. (Number three—at least on the road—according to the AAA? Locking the keys in the car.)
While tires and batteries have also been improved significantly in the last few decades, both are wear items and are subject to the whims of chance, whether it be a jagged root holing a tire or any number of things draining a battery.
What this means, however, is that with just two kits in your vehicle you can fix the vast majority of things that are likely to go wrong in the backcountry.
- A backup for the starting battery
- An air compressor and tire repair kit
Let’s, er, start with the battery. A lot of people now have dual-battery systems in their overlanding vehicles, so the auxiliary can be used to power fridges, etc. without draining the starting battery. Most of these systems have a switch that will tie in the auxiliary to the starting circuit when needed, thus solving the problem of a dead main battery in a few seconds. If there is no switch, the auxiliary can be physically swapped with the main battery. Since the chances of two batteries dying simultaneously—at least when installed with a proper isolating system—are scant, you’re more or less immune to battery woes.
If you have only a single battery for all your systems, I have just one word for you: Microstart. These have been around for several years now and I’ve been preaching their gospel to the point of fanaticism, but I still run into people who have never heard of the product and are blown away when I jump-start their dead 3/4-ton pickup with a battery the size of a VHS tape. I have used and abused a half-dozen of them (we keep one in every vehicle) and they’ve performed perfectly. Early on in their history, master fabricator Tim Scully and I wondered if they could be used for field welding. We duly hooked up three in series and produced several excellent beads, after which the trio continued to work perfectly for their intended use. When I called Scott Schafer at Antigravity Batteries he expressed mingled astonishment and horror at what we had accomplished. (Current Microstarts include an overload device that prevents such shenanigans. Blame Tim and me.) In any case, a Microstart will that ensure a dead starting battery will not leave you stranded. Buy the XP-1 if you have a gasoline-engined mid-size SUV, or the XP-10 if you have a big diesel-powered truck, and top it up (on either AC or DC) every four or five months.
The only real alternative to safeguard a single battery is a low-voltage cutout, which will shut off current flowing from the battery if it senses voltage dropping to levels that would make the vehicle difficult to start. While this might be fine as a backup, I've found that a lot of people who install them are overburdening their battery to begin with, for example by running a fridge while still relying on the battery to turn a high-amperage starter. Better to go with a dual-battery system if you have that much draw.
That leaves tires. As with batteries, they’re a lot tougher and longer-wearing than in years past, but still vulnerable to damage, especially when driven on rough roads and trails. Yet I’m surprised at how many overlanders confine their backup tire kit to a single spare and perhaps a can of Fix-a-Flat. We can do better, and all it takes is a compressor and a proper tire-repair kit.
The repair kit is easy. At its most basic you want a plug kit, which will handle the majority of punctures within the tread area, usually without even needed to remove the wheel and tire from the car. But skip the Pep Boys versions and get a good one. This isn’t just tool snobbery talking: plugging a tire involves shoving pretty hard on the reaming tool and the plug-inserting tool. You do not want a cheap plastic-handled tool breaking during the procedure. ARB makes an excellent plug kit with everything you need for most simple punctures. If you want to step up from that and be prepared to handle virtually any tire problem short of a carcass-shredding blowout (including sidewall splits and broken valve stems), get the Exptreme Outback Ultimate Puncture Repair Kit. It’s expensive at $99, but you’ll never have to buy anything else to repair tires as long as you live.
Once the tire is repaired you’ll need to re-inflate it. While there are air compressors available from $19.95 on up, skip the cheap ones. They fail with miserable frequency, and even when working are so slow that you could hike out, buy a better unit, and be back before your tire is properly inflated. At a bare minimum get one of the ubiquitous Super Flow MV50 units, which are available from around $60. The MV50s have their issues but in general are reliable and reasonably fast, and if you’re a tinkerer there are dozens of web articles detailing worthwhile hacks for the product.
Personally I prefer buying a better compressor to start with, both for repairing tires and for the much more frequently needed function of airing all four tires back up after airing them down for trail driving. To step up in quality look at the Viair units and anything from Extreme Outback. My current favorite compressor is the blindingly fast ARB Twin, expensive but worth every penny. Use the Twin to air up and you’ll be finished with your own vehicle and a friend’s before someone with an MV50 has done two tires.
Part of what defines overlanding is self-sufficiency. Making sure battery and tire troubles can’t bring you to a halt will go a long way toward guaranteeing that self-sufficiency—and if you travel far off the beaten track might just save you a sat-phone call and a very expensive recovery.
A quality combo tool kit
I’m normally a bit leery of tool sets that combine several different types of tools. I like my socket sets to be socket sets and my wrench sets to be wrench sets. Too many combination kits either seemed to be aimed at people who never actually use tools, or upon inspection they prove to be missing critical items.
However, when Graham Jackson and I were attempting to assemble tool kits for our respective Land Cruisers in Australia, we found that tools Down Under in general seemed to be either a) complete rubbish, or b) stunningly expensive. We bought one combo set that was so insultingly bad we wound up simply ditching it with friends to donate or bin as they pleased. It would certainly have failed at repairing any vehicle more substantial than a pedal car.
The last trip Roseann and I took I was determined to secure a high-quality ratchet/socket set and some decent wrenches. Shopping online from the U.S. I found that the well-respected Bahco tools were available in Australia (as well as the U.S.), so I took a chance on a combination kit (#S106 in the U.S.) and had it delivered to our friends in Sydney. I subsequently had an opportunity to use it for some minor but important repairs, and I was impressed. The ratchets have disappointingly coarse tooth counts (54, crude in this day of 72- and even 80-tooth ratchets), but they incorporate quick-release buttons, which I like, and lever rather than palm directional control, which I strongly prefer. Everything was of reassuringly solid construction, and the assortment was broad enough to be considered comprehensive:
- Standard sockets (1/4 and 1/2-inch drive) from 4mm to a huge 34mm.
- Standard SAE sockets from 3/8 to 1 3/16.
- 1/4-inch drive deep sockets from 4 to 13mm.
- Combination wrenches from 7 to 19mm.
- Flex-head wrenches from 8 to 15mm.
- A good assortment of drive bits.
- Sliding T handles and extensions, in 1/4 and 1/2 inch.
- Four impact sockets, 17, 19, 21, and 24mm. Not sure why these are included in a hand-tool set, but if you have an impact driver they’d be suitable for removing stuck lug nuts. And good as spares.
- Plus everything else you can see here in my hasty snapshots.
With the addition of an 18-inch breaker bar (or, alternatively, the exquisite Snap-on SX80A 18-inch flex-head ratchet), I’d feel confident tackling a major field repair with this Bahco set.
The very best recovery tool is . . .
I know, I know . . . there are several much more glamorous bits of equipment with which to decorate a 4WD vehicle—many that are well worth having. But I can’t think of any with the same combination of, 1) Affordability, 2) Reliability, 3) Versatility, and 4) Simplicity, as this most basic of tools.
A great many vehicle boggings occur when two or more tires spin down through whatever substrate you are trying to negotiate, until depth and friction prevent them climbing out. Assuming you’ve already aired down, the simplest way to extract yourself is to scoop out four ramps for the tires to climb. Even if you have a set of MaxTrax to employ, it’s smart to give them a head start with some digging.
You can also use a shovel to add substrate to a hole you have to drive through. If you need to fill a bigger hole with rocks, a shovel will help you pry half-buried candidates out of the ground. If you high-center on a rock or dirt, the shovel can help free you. And of course a shovel is handy for innumerable other tasks, which can’t be said for most recovery-specific products.
So what sort of shovel to have? That’s in many ways up to personal preference. However, I’ve found several characteristics that I think make a shovel better suited for recovery work.
Length: Some experts recommend a full-length handle, to enable you to reach all the way under a vehicle that might need sand cleared from its chassis, for example. However, a long shovel is awkward for most other uses in the field, and much more of a pain to carry in a vehicle. I like one no longer than about 40 inches total, and have found that this length actually works better in a majority of cirumstances.
Handle: I strongly prefer a T or D handle, and if you haven’t tried one I bet you’ll agree with me. A handle perpendicular to the shaft offers far more comfort, control, and power when punching it under a tire to clear sand, and it’s far easier to put sideways torque on the blade when needed.
Shaft: It’s hard to criticize an all-welded-steel shovel such as the Wolverine DH15DP above, which I wrote about here. For sheer indestructibility it has no peer. However, a proper ash or hickory shaft/handle will be perfectly sturdy and is nicer to use in heat or cold.
Combination tools: Not a fan. Again this is personal preference, but I’ve found the tools that combine a single handle with, for example, a removeable shovel blade, axe head, and sledge to be generally heavy and not very good as any individual tool. The axe function, in particular, is invariably miserably balanced and completely lacking in grace. An axe should be a living thing—and, frankly, that balance and grace is a safety issue when you’re swinging a sharp blade. Buy yourself a proper axe and leave the shovel as a shovel.
Folding entrenching tool: Definitely, absolutely better than nothing, but c’mon—you’re not carrying it in an A.L.I.C.E. pack with MREs, you’ve got a vehicle. Get a real shovel. If you really want or need something that compact get one of the brilliant surplus German one-piece shovels like this:
. . . which typically have one side of the blade sharpened as a makeshift axe (or a nasty self-defense weapon that doesn’t look like a weapon to authorities in authoritarian countries).
My favorite recovery shovel is about as prosaic as you can get: It’s the Land Rover T-handled tool that comes in the evocatively named “Pioneer Kit,” which also includes a very functional take-down pickaxe. You’ve seen these clipped to the front wing of inumerable Series vehicles. My first close encounter with one was in Namibia, on a guide’s battered Series IIA that also sported an entire sofa bolted to the roof for tourists to ride on. The shovel was so well-used in Namib sand that the blade was visibly shortened, and shiny as glass.
The Pioneer Kit is available through UK surplus stores online; occasionally as NOS (New Old Stock). If you happen to be there you can find them for less at one of the myriad four-wheel-drive shows. The shovel’s blade extends to a long shank that encloses nearly half the wood (ash?) shaft. If anything the blade is a bit thicker than it needs to be. In any case it will demonstrably last through years of abuse in the Namib, probably a lot longer if you aren’t constantly needing to dig out a Land Rover with a sofa on the roof.
U.S. manufacturer A.M. Leonard offers a forged D-handle shovel that looks excellent, although I’ve not seen one in person. Ditto with U.K. maker Richard Carter.
Whatever you decide on, make sure you actually keep it with you. I give you my situation a few weeks ago, camped on the North Rim of the Grand Canyon with a few friends. Roseann and I had both our Tacoma/Four Wheel Camper and the FJ40 along, and when she needed to dig out an existing fire pit she asked me where she could find a shovel.
"Uh . . . "
Fortunately our friends were better prepared.
Update: Correspondent John Wilson tells me that the BLM in the Owyhee region (Oregon, Nevada, Idaho) requires one to carry a full-length shovel, presumably because it is easier to use to put out a spreading campfire. My own advice would be to make sure your damn campfire can't spread in the first place, but thanks to John for the heads up.
A proper shovel
While equipping our Land Cruisers for a trip across the Simpson Desert, we picked up a cheap shovel at a military-surplus-cum-Chinese-camping-gear store in Sydney. Just how cheap became apparent the first night we tried to dig a fire pit. The shovel literally bounced off the ground—the blade simply bent and sprang back under any force at all. It was so bad all we could do was laugh.
That won’t happen with this one.
We needed indestructible shovels for the Camel Trophy Skills Area at the Overland Expo, and a short web search convinced me that those from Wolverine Hand Tools fit the bill perfectly.
If you name a shovel “Wolverine” it had better be tough, since its namesake is known for chasing grizzly bears off their kills to have a snack. Indeed, this one (DH15DP) is solid, welded steel except for a rubber foot brace (which can be changed side to side). The blade has a sharp wedge tip and most definitely will not bounce off the ground. The 26-inch shaft is steel, and welded to the blade around the perimeter of the joint on both sides. It’s not the prettiest weld on earth—there’s spatter under the paint—but it’s not going to come loose. Likewise, the D handle is steel and welded.
It’s obviously not the lightest shovel you can buy, but its utility will extend beyond digging fire pits. Prying lodged rocks from under the frame rails of a high-centered truck should be no trouble. And the 15-inch blade offers plenty of surface area for scooping sand out from under a buried vehicle to insert Max Trax (there’s also a 12-inch version). Well-recommended.
Look for them here.
Solutions to problems that never existed
Human ingenuity is a wonderful thing.
Usually.
In the world at large, we can be grateful for those inventions that have benefited mankind and transformed lives: home espresso machines, noise-cancelling headphones, the Porsche 911. Oh, and dialysis machines and stuff.
In the overlanding world we have much to be thankful for as well: the 12V fridge of course, but also LED lighting, MotionX-GPS Pro, diff locks, Star Walk . . .
Then there are . . . the others. Products that make one—or at least me—think, What were they thinking? See if you agree/disagree with any of these. No offense taken or given if you don’t. further suggestions welcome.
Spork
Here’s a brilliant concept: “Let’s make a fork with triangle-shaped tines incapable of penetrating anything firmer than a cube of rotten tofu, and a spoon with built-in drainage cuts in the end so any liquid picked up in it dribbles out on the user’s shirt. Then let’s combine them in one utensil!” And they're everywhere. Even Snow Peak, purveyor of many otherwise stellar products, wastes bits of the world's finite supply of titanium on their own version.
I know genuinely smart people (including blood relations) who claim to be fans of this idiotic device. I’m convinced they are simply mortally embarrassed at having been fooled into parting with good money for one, and are determined to bluster on and insist it’s a fabulous tool. It’s not. It’s dumb. Buy a fork, and buy a spoon (Snow Peak makes nice ones). Your shirt will stay cleaner, and you can eat steak instead of rotten tofu.
Incidentally, if a normal spork is too mundane for you, there’s the Tactical Spork from Ka-Bar:
Single-use soap
You know how difficult it is to get the last few uses out of a bar of soap when it’s been reduced to a sliver? How about paying for a pack of them? The entire concept of “single-use” soap is flawed to begin with. Single use for what? Washing your hands? What if your hands are really dirty? A shower? What if your “single-use” soap runs out when you’re only half clean? You get another, and have a half-use soap sliver left over? All this ran through my mind the first time I saw these things on a camping equipment site. Subsequent consideration hasn’t softened my stance.
One thing’s for sure: You’ll get taken to the cleaners while you’re getting cleaner. I found a pack of single-use soap “leaves” (actually shaped like leaves; cute) on Amazon. Twelve bucks for a pack of 20. That’s 60 cents every time you wash your hands.
Mini survival kits
Here’s the situation: You’re planning to head out into the wilderness with your 4x4/motorcycle/bicycle/backpack. And it crosses your mind that you might find yourself in a situation in which you lose everything—don’t ask how—and will have to stay alive, feed, water, and warm yourself, and find your way back to civilization by relying solely on the contents of the survival kit you grab before your 4x4/motorcycle/bicycle/backpack falls off the edge of a 5,000-foot cliff/is stolen by bandits/burns to ashes. So, of course that survival kit needs to fit inside a Peppermint Altoids tin, right? What’s in there? Let’s see—a razor blade for a knife, to skin the rabbit you catch with the included .00006” diameter “snare wire,” a condom to carry water (my favorite!), safety pins for. . . for . . . well, I’ve never been sure what for. A “fishing kit”: ten feet of ten-pound-test monofilament and three #12 hooks. A micro ferrocerium rod fire striker, of course, because no self-respecting mini survival kit would come with anything as plebeian and effective as windproof matches. And a button compass to precisely determine the difference between northish and sort of south.
At least the Altoids kits are cheap. I reviewed another mini survival kit here that was not.
The words “mini” and “survival kit” do not belong in the same sentence. If your life is going to depend on a single container of equipment, there is no reason it needs to fit in your back pocket. The best “pocket” survival kit for a large portion of the developed world is an iPhone. If you go more remote, carry a real kit with useful components.
“Spec-Ops” survival knives
I’ve ranted in detail about these before, here. Suffice to say, burdening yourself with one of these cartoonish monsters unless you have a very, very high chance of needing to “egress from your downed helicopter’s canopy,” chop through a concrete block, or take down a sentry with an occiput strike, is just silly. A good bushcraft or standard hunting knife will perform far better for 99.999 percent of the things you really need a knife for—including survival.
Pop-up tents
You know the kind I’m talking about—a flat disk of fabric-covered springy wire; you fling it open and it either becomes a tent or a windshield shade (“Dammit, we left the tent at home again!”)
These things are a tent connoisseur’s ultimate nightmare: Sea kayaking the arctic coast, I stop to pitch camp to sit through a rapidly approaching Force Five storm, and when I pull my bombproof, four-season Hilleberg tent out of its stuffsack it has transmogrified into a Barney-purple and Minions yellow pop-up dome tent. I wake up in a cold sweat. “Tent dream again?” Roseann says sleepily.
I’ve actually used one—it came with a hired Land Cruiser in Egypt. It would collapse in a breeze that was insensible to a wet finger, and its admittedly instant pitch was more than offset by the fact that it required two people, five arms, and eight tries to accomplish the six-sequence coiling motion needed to return it to its case. Stupid.* Read more here.
*Note that I make an exception for pop-up shower/toilet enclosures, which do not need to keep you dry and safe in a storm or wind.
Airing down—and up—the pro way
One of the most frequent questions people ask me is, “What’s the the best thing I can do to improve my vehicle’s off-pavement performance?” Many of them seem distinctly disappointed when I answer, “Air down your tires.” I’m sure they’re hoping I’ll facilitate some expensive and impressive modification—diff locks, external-bypass shocks, three-piece titanium wheels, something that would justify putting a stylish brand sticker in a window. But the fact is that nothing is easier to do or more effective at providing several instant benefits than reducing your normal street tire pressures to suit the immediate conditions. I’ll repeat: Nothing.
First, lower pressure increases traction by increasing the contact area of the tire and allowing it to better deform around obstacles and grip them. Flotation in sand is enormously enhanced with the longer footprint provided by lower pressure (not so much greater width as many suppose).
But the advantages don’t end there. Lowering pressure alleviates stress on the vehicle by effectively reducing the spring rate—the tires flex enough to absorb impacts that would otherwise have to be dealt with by the springs and shocks. That translates to much greater comfort for the driver and passengers.
Finally, the above characteristics contribute to reduced impact on the trail. We saw first-hand evidence of this on a recent crossing of the Simpson Desert in Australia, via the Madigan Line—so-called after Dr. Cecil Madigan, who led the first scientific expedition across the area in 1939. The Madigan Line cuts directly across the huge field of parallel sand dunes that characterizes this part of the Simpson—1,130 sand dunes to be more or less precise. The dunes themselves are stabilized and well-vegetated, but the bare track still needs to ascend and descend each dune, and despite the very sparse traffic on this route the final approaches and crests are often cratered with “hoon holes,” where those who disdain airing down—or even engaging four wheel drive—have left huge divots from futilely spinning tires or frantic, lunging ascents.
Graham and I actually aired down our Land Cruisers prior to hitting the dunes, on the stretch leading to the old Andado Station, a fine track but well-known for its long stretches of corrugations (or washboard as we refer to them in the U.S.). I reduced our pressure from 40 psi, which we’d run on the paved Stuart Highway to Alice Springs, down to 32, and Graham did likewise (he’d found his tubed tires on split rims at a harsh 50 psi). It took much of the sting out of the sharp undulations and eliminated the skip-fishtailing that can occur with higher pressures. (An Australian writer described those corrugations as “brutal.” All I can say is he needs to see the corrugations on the seven-mile dirt track to our house in Arizona. Or those on the road from Namanga to Amboseli. But that’s another story.)
Once in the dunes, we further reduced pressure to around 22 psi. This is well above the 14 we might run in very soft sand, but it worked perfectly on the combination of flat, compacted inter-dune track and the chewed-up ascents and descents. We even summited the famous Big Red dune outside Birdsville with no drama.
Once past Birdsville, on the high-speed gravel Birdsville Developmental Road, we re-inflated—and that’s where the catch is for many people who grasp the concept of airing down, appreciate its advantages, but rarely if ever do it.
Why? Because a lot of those people carry a compressor that cost them as much as a couple of pizzas and is about as effective at actually adding air to a tire, despite the “150 PSI!” claims on the box. A single 45-minute session laboriously moving four tires from 25 psi to, say, 28, while their $29.95 compressor buzzes and vibrates in circles like an enraged chihuahua, and that’s it. The thing gets tossed in the bottom of the tools, to be used in the event of an actual flat, if at all. The same people likely used the point of their Swiss Army knife to depress the valve to deflate each tire, another laborious procedure. It’s little wonder they inflate the tires on their new truck to 40 psi and never budge from that.
We knew better. And we were, after all, in Australia, home of some of the best expedition equipment manufacturers on the planet. In Sydney we had picked up a pair of ARB E-Z deflators, and two ARB portable Twin compressor kits (CKMTP12). The single-cylinder ARB High Output compressor on our Tacoma has been working perfectly for several years operating a locker and inflating tires, so I was eager to compare the more powerful Twin in field use.
Airing down takes less than a minute per tire with the E-Z deflator, which unscrews and captures the tire’s valve core, allowing a much greater volume of air to exit the valve stem, and gives you precise control with its sliding actuator. The only faster way I know to air down four tires is with a full set of the superb set-and-forget CB Developments Mil-Spec automatic deflators—but that full set will cost you $400, versus $40 for the ARB unit. An E-Z choice, if you will.
Regarding portable 12V compressors, as with so many other products it’s been my experience that you get what you pay for. The $30 units that plug into a cigarette lighter simply won’t cut it for field use. I know people who’ve been happy with the ubiquitous Masterflow MT50 and its variations, which are available for less than $100; these clip directly to the battery, meaning they can draw more amperage, but they are still achingly slow, and I can recall at least three failures related to me by users. Simply put, if you’re going to go the pro route for airing down (and repairing) tires, you need a pro-level compressor. You do not want to get caught after a section of soft sand with all your tires at 14 psi, no way to inflate them, and 30 miles of rocks ahead. (Especially when it's been six days since you've seen another human.)
Ignore the psi rating—virtually any pump will produce more than enough theoretical pressure. It’s the cfm (cubic feet per minute) rating and duty cycle you need to evaluate. The cfm is self-explanatory. Duty cycle refers to how long the unit can run before it needs to shut down and cool off. A 25-percent duty cycle means the pump can run for 15 minutes out of an hour. It’s easy to see the relationship: A high cfm rating means little if the duty cycle is poor, and a 100-percent duty cycle means little if the cfm rating is below standard. Furthermore, some compressors display an impressive cfm rating at zero psi, but will fall off significantly with higher pressures. Look for factory specs that list both.
The Australian-built ARB Twin boasts a 100-percent duty cycle, produces 6.16 cfm at zero psi and an impressive 4.68 cfm at 29 psi. How does this relate to the real world? Back on the Birdsville Developmental Road to air up, I hooked up the Twin’s leads to our Land Cruiser’s battery, flipped the rocker switch, connected the chuck to the first tire (still at 22 psi), settled back on my heels to wait a couple minutes, and, er, what? The tire seemed to rise awfully quickly. I disconnected and checked the pressure: 42 psi. I was only aiming for 38 . . .
I bled a bit out and moved to the other three tires. I didn’t set a watch to any of them, but it certainly took no more than a minute per tire to reinflate from 22 psi to 38. That rivals my benchmark for powerful compressors, the Extreme Outback ExtremeAir Magnum. And the ARB doesn't have a single "Extreme" in its name.
As a reliable and durable tool for remote use it would be hard to imagine a better configuration than the ARB Twin, given the extensive redundancy: Two all-ball-bearing motors, two cylinders, two inline fuses, and internal thermal protection for each motor. Twin air filters are washable sintered bronze, not paper. It’s highly moisture and dust resistant (the cooling fan is actually sealed to IP55 specs); the cylinder bores are hard anodized and the piston seals are Teflon-impregnated carbon fiber. In addition, the portable kit incorporates a four-liter aluminum air tank, which enables the system to run most air tools (it’s regulated to 150 psi). For the distinctly premium price, I wish the kit came with the ARB inflator that incorporates a dial gauge, rather than the simple clip-on chuck that is standard. But the waterproof case is strong, and the organizer pockets keep hoses and accessories neat—an underappreciated feature on expeditions where entropy nudges things toward clutter. The battery clamps are sturdy, the inline fuses easy to access if necessary, and there's a solidly mounted quick-release fitting for the air line next to the (lighted) power switch. You’ll know you’re dealing with a substantial piece of equipment when you pick it up—the whole package weighs 33 pounds, about as much as a Hi-Lift jack. The compressor alone weighs 19.4.
If you prefer a built-in compressor (I normally do, but we haven’t yet decided on the final configuration in the Troopy), the air filters of the Twin can be relocated, rendering the entire unit submersible. ARB was not messing around when they designed this compressor.
The Twin is a significant investment ($830 for the kit; $520 for the compressor alone). But consider these two facts: 1) As stressed above, varying your tires’ pressures to suit conditions will do more than anything else to enhance your vehicle’s off-pavement prowess, your comfort, and the condition of the trail, and 2) Tire failure is by a significant margin the number one reason for breakdowns in the bush. With a high-quality compressor such as the ARB Twin you have both scenarios covered with professional-level ease.
Bogert Manufacturing wheel chocks
Chocking your vehicle’s tires is one of the most basic and critical safety procedures you can follow before changing a tire, winching, or working underneath it. Yet how many of us ever use anything but nearby rocks or logs to do so? Not only are you at the mercy of what’s available (Will this work, or do I need that bigger one over there?), but if you happen to be leading a trip or are otherwise in a position of some assumed authority, it lends a rookie taint to your otherwise faultless command presence to be seen looking around for rocks.
I thought about this recently while looking around for rocks.
To make matters worse, I had a good set of chocks with me—the clever folding units made by Land Rover—but they were inconveniently stashed in a compartment under the rear jump seat of the Tacoma, which itself was under several layers of Pelican cases. So I took the lazy route.
Lessons learned: a) Have stuff like this easily accessible, and if it isn’t, b) Follow Graham Jackson’s First Rule of What to Do When There’s Trouble, which is, Slow down and brew a cup of tea, and then Jonathan Hanson’s First Rule of What to Do When There’s Trouble, which is Use the right tools. Sorry Graham. And me.
As much as I like the Land Rover chocks, their lightweight, folding construction pretty much relegated them to tire-changing and working-under duties. Thanks to the fertile mind of Richard Bogert of Bogert Manufacturing, I now have a set of heavy-duty, winching-compatible chocks.
Constructed of 3/16ths-inch steel and heavily powder-coated, the Bogert chocks take up virtually no more room than the folding ones if you stand them on edge in the corner of a cargo box. A set of them comprises not two but, properly, four, so you can anchor two wheels on both sides, or four wheels on one side if you’re on a hill. Additionally, a set of holes and slots in each chock allows you to chain two together on either end of the wheel to prevent shifting if the truck jerks back and forth under a load—nice. Each set of chocks comes with four chains, so you can anchor each pair of chocks on the inside and outside of the wheel if needed. The result is one solidly immobile truck.
The set is now stored in the “Camper Setup” Wolf Pack box that rides just inside the door of the JATAC's Four Wheel Camper. So accessing proper chocks will be as easy as picking up a rock, and my faultless command presence can remain intact.
