adanacsleds.com Double Driver Sled Not just for tour companies anymore! Adanac is making several styles of double driver sleds. There are great reasons for owning one of these sleds in addition to your racing sleds or “tour” sleds. If you are a musher with friends that always want to go for a “ride”—try one of these sleds. You don’t have to pack the friend in your sled bag and they can get the experience of dog mushing. We make double drivers where two people can stand up in tandem. They each have their own upright stanchions, handlebar, double claw brake system, footboards, and drag mat (if desired). These sleds are great for training and great for tour operators. They are built to last using hand-picked ash and polyethylene plastics.

The two Arctic Oven Pipeline models weigh less than 20 pounds and are quick and easy to set up.

These are made from the same material as our leggin’s. We put 3 pockets inside so the musher can put hand warmers in these pockets to keep the shoulder muscles loose.

critterwoods.com Critterwoods Snow Hook This snow hook has been in production for 12 years. It is a once in a life time purchase where as it is made of almost indestructible material, tempered stainless steel that is lazer cut and tig welded for added strength with a total weight of 3½ lbs. You should only have to replace it if you lose it or just want another. The hook itself is made in a way that when pulled from the front it naturally wants to dig down and sets itself. I have got into the habit of just dropping it into the snow and letting it set itself. The best part is it will right itself. As soon as it hits the ground it will dig in and you are stopped. There have been many Critterwoods snow hooks that have made the trip to Nome as well as traveled the Yukon Quest and most of the other major events world wide.” Gary Chapman, owner. Mushing Magazine

hilleberg.com Hilleberg staika 2-person tent The Staika is all about simple – but simple does not by any means equate to “sparse.” Easy to pitch, immensely stable, remarkably spacious, and quite light, the Staika is an excellent “go to” tent for any use where sturdy strength is the high priority. We originally designed the Staika for paddle tourers, who wanted a highly stable, fully free standing tent for handling tricky pitching conditions. Since then, it has garnered a large, loyal following amongst a wide assortment of other adventurers: mountaineers, polar travelers, and ski tourers find it a supremely stable base camp tent in all conditions; bicycle tourers love its simplicity and completely free standing construction; and even regular backpackers find great comfort in its roominess and relatively light weight as well as in its strength and stability.
November/December 2011
Hilleberg akto single person tent When we first introduced the Akto over a decade ago, we did not know that it would become as popular as it has. Although only slightly heavier than a bivy bag, the Akto offers near-luxury, all-season shelter for the solo traveler – lodging that includes a vestibule and a packed size small enough to fit into a side pocket on many packs. The Akto has true all-season capability, yet its total weight is only 1.6 kg/3 lbs 8 oz. Our tunnel design and linked inner and outer tents makes it very simple and quick to set up, and provides a high degree of stability in all conditions. The Akto is ideal any time you need the lightest weight, all condition solo tent. It is especially good for long trips of any kind, in any season, where light weight is a very high priority. And while it was not designed for extreme use in exposed and/or above tree line terrain, the Akto has proven itself on extended polar expeditions, and so will stand up well to all conditions.

howlingdogalaska.com SKIJORING LINE
Our skijoring lines have been the top pulling lines on the market for many years now. Their superior design and durability far surpass lines manufactured by our competitors. Unlike other lines, our skijoring lines have bungee fitted in to a sleeve made out of durable tubular webbing. There is no frying, no wear and tear present the way it is with lines made out of a Poly line. Plus our two dog line features a built in bungee for each dog, which is far superior to a line fitted with one bungee only. Having a double bungee ensures good, evenly distributed pulling power and reduces tangles from dogs not pulling equally. Our skijoring line is also an ideal line for canicross (running with the dog), bikejoring, scootering, walking dogs hands free, dog trekking and as a one dog / two dog sled pulling line. EAR PROTECTOR Our Ear Protector is a must for any racing dog that suffers from chronic ear frost bite. Racing pointer crosses are especially susceptible to this condition and will benefit from wearing such protector. The Ear Protector has been designed to stay on the dog’s head while the dog is running. It is also suitable as an ear protection for any pet dog with very thin or cold sensitive ears. We also have customers, who bought our Ear Protector to put on their long eared dog (such as Basset Hound) while the dog is eating – to keep the ears out of the dog food dish. Our Ear Protector is made out of 4-way stretch, wind resistant fabric and fits snug on a dog’s head.

The calculation of the theoretical light output of a lighting system based on the LED-manufacturer’s stated maximum light output, and 2. The measurement of the actual light output of a lighting system using a calibrated integrating sphere. Some manufacturers use the first method, which can be deceiving because there are many other factors which contribute to usable light and available light output. It would seem that the manufacturers and products we tested use the second method, as the light output of the units was in close proportion to the listed lumens. Mushing MushingMagazine Magazine

the
DARK ART of Carbon Fibre By Greg Sellentin
Lighter and stronger?
Lately the use of carbon fibre
technology in the construction of dog sleds has become more commonplace. Carbon fibre is a material that consists of thin, strong crystalline filaments of carbon. Carbon fibres are used in high-strength composite materials for aircraft, automobile and architectural structures, and in other applications where light materials capable of withstanding high stress are required. It can be used to strengthen existing material, or on its own to produce a lightweight and strong component for a dog sled. ¶ I first saw carbon fibre used for the stanchions on a Norwegian brand OT sprint sled at the 1995 IFSS WC races. Relatively small diameter tubing brought on the response from obervers that it was a ridiculous material to use in such a critical area of stress in a dog sled. But, having been very familiar with the almost mythical, at the time, substance my first thought was, “Ok, here we go again.” I had seen the “lightweight arms race” take place in many sports equipment I had been involved with from windsurfing, to racing bicycles. Although the beauty of these lightweight parts and the weight savings were real, the high cost and complexity of manufacturing of such parts tended to drive the cost of participation higher and higher. ¶ Are space-age composite materials cost effective, useful, or even recommended in the construction of a dog sled, or are they overkill and just the latest trend or marketing fad? I spoke with a couple of well known and respected sled makers and the answers were interesting. 12

O
ne of the interesting things about Carbon Fibre (CF) is its failure characteristics. By that I mean that steel, and to some degree aluminum, will flex to a point when stressed and return to its original shape, but if forced beyond that point will result in permanent bending. Steel has the ability to be bent back after this type of stress, aluminum much less so, but CF has a “catastrophic failure characteristic” meaning it will flex to a point and return to its original shape time after time, but if forced beyond that point, will result in splintering or shattering. Granted, if used properly, this material can be very, very tough. Anyone who has watched a 6'4" NHL defenseman wind up into a slapshot from mid-ice can relate to that.
H
ans Gatt has experience building dog sleds dating back to before he emigrated from Austria to Canada in 1990. He started experimenting with carbon fibre parts in testing on his personal sleds about 4 years ago. Because of the complexity of laying up the carbon fibre sheets and resins, Hans uses, as other sled makers do, an off-the-shelf rectangular tubing which is intended for use as high-end hockey sticks. It turns out that the hockey stick toughness, size and shape are perfect for dog sled stanchions. Hans orders his direct from the factory without logos or plugs, just hollow tubing. “Although I have other options for having them made here near Whitehorse, YT where we have plenty of high-tech sporting industry specialist manufacturers that use CF in boats, bikes, etc, the best product and the most cost effective one was to order these hockey stick blanks.” I asked Hans if he has seen any problems associated with the lighter than aircraft aluminum material, and he emphatically said, “No. I used the same sled for 3 seasons, through some very tough Yukon Quests, and Iditarods, and haven’t seen any problems. I was initially wary of the cold, but have used it down to 60˚F below zero and haven’t experienced any failures. It might break in a hard crash, but so will wood. Most of the sleds I build are still made from aluminum. Really the only reason to use CF is the weight savings. It is a lot harder to work with, harder to drill—you have to use a core where the bolts and brackets are attached to it, and it is more expensive.” Hans explained. I had one more question for Hans - Is it worth the price difference from aluminum? He explained, “I don’t know. Every sled I make is available with CF stanchions as an option, it is an individual choice. I absolutely believe in simplicity, what keeps you out of trouble in a race is most important, that’s what counts. The weight savings is quite impressive though, if that is what you’re looking for. For comparison, I weighed each a 56 inch or 142 cm Carbon and Aluminum Stanchion. The Aluminum is 602 grams or 21.3 oz, and the CF is 308 grams or 10.8 oz. I find the difference in weight quite significant. For me, if the stanchions weren’t available commercially, if I had to have them made specially for sled building applications, it wouldn’t be cost effective.” Hans finished with.

olby Morrison of Lone Wolf Sleds echoes many of the sentiments that Hans does about CF, in that it is harder to work with than other materials. He has been using it in sleds for about 3 to 4 years, and “playing around with it” for about 6 years. He uses a Chinese made hockey stick blank that he orders in .049" wall thickness. He also has not seen any brittleness in cold weather. Kolby estimates that they are as tough as wood, and save 3 or 4 lbs maximum. The cost for all that weight savings? “Compared to wood laminated runners, the extra steps needed to both laminate in strips of carbon fibre, and then to vacuum bag the whole runner in a carbon/kevlar weave adds about $300 to the runners alone.” Kolby adds, “I can make a more flexible, yet strong runner because I can rely on the CF for strength and use less wood than a wood only laminated runner. These runners are laterally stiff, and resist warping, but have great vertical shock absorption properties.” He added. Kolby traveled to Vancouver, BC to learn the tricks of vacuum bagging CF runners from a downhill ski manufacturer. “In the future, we are going to look into making other sled parts such as brackets and stanchion junction plates out of CF.”
C
ody Strathe of Dog Paddle Designs uses a mix of traditional wood and high tech fibreglass/carbon fibre/kevlar epoxies to construct his beautiful yet bombproof sleds. “The feeling you get when you drive a wooden sled is different
Clockwise from top left: The runners of Cody Strathe’s Dog Paddle Designs sled start out as laminated wood. He then utilizes a cloth CF sleeve that is stretched over the runner. Epoxy resins are mixed and used to wet out the cloth. The whole runner is then encased in a larger tube that is heat shrunk around the whole assembly to squeeze out excess resin and air and to conform the CF epoxy exactly to the runner. The laminated wood stanchions are encased in clear fibreglass cloth and resin the entire length, but the higher stress ends are also encased with CF and cured in the same manner as the runners. The Danler Hornet XC-URS sprint sled weights just 17.6 lbs with a snow hook! The sled sells for over $4500 US and is a limited production run. It utilizes CF stanchions and drag mat armature as well as a new aluminum snow hook with carbide tips. This is the sled Hans Gatt used in last year’s Quest and Iditarod. It is a combination of CF stanchions and aircraft aluminum. Lonewolf Sleds, long distance tail dragger model uses hockey stick blank stanchions and vacuum bagged CF encased laminated wood runners.
than what you get when you drive an aluminum or fully CF sled. I wanted to retain some of that traditional feel. Also I’m a wood worker, that is my specialty. I find wood is also really nice to look at, but I wanted to make them stronger without adding too much extra weight, so that they are more useful to mushers who are racing. By using these exotic materials in high stress areas, I can cut down on the sizes of the wood pieces, making the whole sled even lighter. After many seasons of use both recreationally and in racing I’ve only seen one failure. It was a very hard impact and the wood inside the CF reinforcement area actually shattered but the CF didn’t–holding the whole thing together. Because of that I get a little nervous using CF alone. I’d rather make stronger sleds than lighter sleds. The CF/ kevlar combination I use on the runners is actually stronger than CF alone because the kevlar is more flexible, not as brittle as CF, and more resistant to abrasion. I’ve made them out of just kevlar and they are not stiff enough, and conversely just using CF makes them too stiff.” Cody explains. Instead of vacuum bagging his runners, which is a very time consuming process in that you can only do one set at a time, Cody has adapted a heat shrink tubing that he can do many sets at once with. The use of CF for dog sleds is understandably here to stay, and as the availability becomes more widespread, the cost of using it will inevitably be reduced. As for those OT sleds made back in the early 90’s with the thin, fragile looking CF stanchions, they are still in use today cruising around the trails in Alaska. • Mushing Magazine
