Icing on waxless skis
Me
To complicate matters further, hot waxing can make bc skis too slippery for difficult terrain conditions. Booker Bense _ This is complete and utter crap. Well, uhm... Thank you. Waxing only improves turning and control. I think you don't have experience of the difficult terrain conditions I was discussing. If you haven't done it, I guess you'll just have to take my word for it: Handling well-glide-waxed skis simply is more difficult in small-scale steep forested terrain (off-trail/off-track). In such conditions grip (not only backwards, btw) tends to be much more important than glide, but... If you need slow skis to stay in control then you should leave your skins on... not so much, that killing the glide altogether with skins is a good idea. With small-scale terrain, putting skins on and off for the ups and the downs, just isn't practical either, as you'd have to do it all the time. What comes to "turning", I assume Booker is talking about high-speed turns, like telemark turns. High-speed downhill is a non-issue in difficult terrain, however. _ Ski bases are manufactured in two ways, sintered and extruded poly. Extruded base skis are pieces of junk because the base has few if any pores to hold the wax. You only find this construction on really cheap skis. This is complete and utter... g Eg, there are four Finnish manufacturers that currently manufacture backcountry forest skis. Peltonen and Karhu seem to have chosen non-porous bottoms, and Järvinen has porous ones. I haven't skied with Harju's, but I'm quite sure they are non-porous too. Järvinen switched from non-porous to porous for about ten years ago - and not everyone was happy with this! None of the four are "really cheap skis", and Järvinen isn't the most expensive of the lot, btw. Peltonen is the current contractor for military skis (or was at least last year). Peltonen's mil skis are very similar to the civilian ones, including the non-porous fish-scale bottoms. Besides, not holding wax properly obviously isn't an issue with waxless skis. In the case of fish-scale non-porous bottoms, waxless isn't a misnomer, although even such bottoms _can_ be waxed - it just doesn't stay on that long - and in the case of severe icing conditions, even such skis need to be waxed or otherwise anti-icing treated. _ It's wax IN the base that makes skis perform, not wax on it. Wax _on_ the base keeps sticky snow from sticking. That's the issue in anti-iceing. Ski performance isn't a universal attribute - whether some skis perform well depends very much on the actual conditions thery're used in. |

If the skis are sticky enough so that they help you not go forward when you are in steep forested terrain, they will suck when you come to an opening and don't want them to stick. Many years ago, I was skiing up a hill. I was new to wax, and my skis were sticking much better than I expected. Nice day, making good progress, all was wonderful... Then I bumped one of my skis and knocked loose the snow that was stuck to the bottom and that ski didn't stick any more.

In such conditions grip (not only backwards, btw) tends to be much more important than glide, but... Hal Murray I can't figure out what you are trying to say. My point is that proper waxing makes handling more difficult in certain conditios (steep small-scale rough terrain, off-trail), and actually lowers the average speed. If the skis are sticky enough so that they help you not go forward when you are in steep forested terrain, The differences here are subtle. An unwaxed non-porous base ski will still glide pretty well forward, but it is easier to handle especially in difficult climbs (up or down) than a properly waxed. It's my experience with myself and others on the skis. they will suck when you come to an opening and don't want them to stick. Of course, in easy terrain, maximal forward glide is desireable. It's a compromize. The easier the conditons become, the more the optimal ski will resemble a XC racing ski - small, light, carefully waxed and matched, and, btw, definitively without fishscale bottoms! While glide is important, minor differences in glide are very secondary in difficult or heavy skiing conditions. In soft snow, flotation and tip-flex are what really matters. The backcountry (forest) skis I'm discussing are typically 210 to 280cm tall and 7cm wide skis. They also have, typically, insufficient camber stifness for the weight of the skier by XC standards: Ie the kick base often 'drags' a bit, which kind of makes smaller differences in the glide waxing irrelevant. For bc skis, a careful stifness/weight match would be rather useless too, as the skier weight will vary upto 60lbs or more depending on the pack worn. Too stiff is a no-no though, it kills mobility. |

_ Any ski that can't be waxed is just a snowshoe with delusions of grandeur. Nonsense. Unwaxed "waxless" skis beat snowshoes with ease in speed, dexterity and efficiency. Not to mention fun. And with a wide margin on all points. _ You're talking about skis and conditions that really have no parallel to us North Americans. The only 280cm skis you can get in the USA are jumping skis. For the conditions you describe, tight trees and deep snow, I would think a 280cm ski would be very difficult to maneuver, waxed or unwaxed. As I said, the backcountry forest skis come in different lenghts, current ones typically 210 to 280cm, all of these nowadays 7cm wide. For the conditions that I described, steep and small-scale, I prefer my 225cm shorties, although 250cm is still manageable for me (177cm tall). I find that heel turns and fishbone - the factors limiting the mobility of longer skis - are still practical with 250cm. Longer skis yet (even 300+cm) are markedly more efficient in easier (ie less steep, more open) terrain in deep soft snow conditions. In easier terrain glide waxing helps too, btw. The soft snow doesn't need to be that thick in order for the longer skis to pay off - two feet is plenty enough. My point about waxing making skis more slippery and thus more difficult to handle in steep small-scale terrain is entirely unrelated to ski-lenght, however, as it affects handling in a completely different way. For open fjelds (gently rolling mountains) with packed snow, telemark/"backcountry" skis are often used over here too: stiffer, shorter, steel edged. Forest skis are quite usable in the fjelds too, however, although the lack of steel edges can be a problem. The other solution to this problem I've seen is the Siberian one of very wide ( 100mm + ) and relatively short skis. Such skis are used in Finland too, but aren't very common. I've got a pair of Karhu's Jakt ('hunting') skis 170cm x 12cm, iirc. They resemble the (shoter) Karhu Metas(?) sold in NA, but come with fishscale rather than permanent skins. Such skis are rather similar in dimension to ancient ones found in archeological excavations, and represent an early part part of the evolution from snow shoes to short skis to unequal lenght skis (long glide ski and short skinned kick ski (kalhu& lyly)) to equal lenght cambered modern skis. Wide and fat was much easier to manufacture with primitive means, and, more relevant to modern times, requires much less skill from the skier. But, they are easily outperformed by a reasonably skilled skier on proper (longer) skis in practically any terrain. There are several problems with short&fat: The biggest one is the lack of end flex: a short ski simply can't flex that much. Firstly, the lack of flex tends to result in noseplants in rough terrain, as the tips submerge and get stuck rather than bend over an obstacle. This is very obvious with XC-track skis in rough off-trail too, btw. Secondly, submersion of stiff tips severly hurts practical flotation when opening track - again, rather the same as with small XC skis. In addition, more snow has to be displaced with wide&short than with long&thin with similar surface pressure, so opening track is heavier with thick shorties for this reason too. Otoh, thick&fat of course outperforms small XC-track skis in opening track due to the better flotation allowed by the lower surface pressure. |

Hey Markus (and Booker), First off, long time no "see". Hope all is well with you. Hi Dave, nice to see you too . Markus, 4 or 5 years ago, you used to have some pretty instructive pictures posted to the web of you and a friend bashing about. This would be a great time to repost a url if one exists. I seem to get involved in discussing backcountry forsest skis almost every year, below's an extract from rsn last winter which has some URL's. Each time it bugs me that I rarely carry a camera (and when I do it's an analog one) and all the coolest tricks remain undocumented. Some of the modern forest skis are strong enough to allow powerful techniques that would have easily broken the old wooden ones, but people in general tend to be unaware of this. Perhaps me&co should some year do a forest ski&technique documention trip. I might have a few old pics of the gear itself non-online, and, if I can find them, I could e-mail them on request (the same ones Dave got years ago). : I don't know of any detailed online pics of the skis themselves. : Below are some links to pics on the web pages of some of my : friends, where various forest skis can be seen. : Some of the pics show typical conditions, and others : not so typical at all, yet others are rather old and : obscure . Happy surfing. : http://www.sll.fi/mpe/vodla/88Sy.JPG : http://www.sll.fi/mpe/vodla/92K.JPG : http://www.megabaud.fi/~jel/pp/sarjak1.htm : http://www.kolumbus.fi/laaksonen.jou...nat/lemm98.htm : http://www.sll.fi/mpe/sisa/smhl/index.html : http://www.sll.fi/mpe/sisa/oo/003/index.html : http://www.sll.fi/mpe/lapinmetsa/panoramas/index.html Also, if you have any urls about NATO bindings and boots, that would be cool too. Unfortunately, still none. There's a good pic of old Swedish mil bindings on old skis with new boots, though: http://www.billingedalen.com/bilder/m90vkanga.jpg Btw, Erä magazine of this month tested about all the off-track skiing gear that's currently commercially availble in Finland. Skis, poles, bindings, boots. The story isn't available online though. Nato bindings were tested too, although it was noted that the availability is bad. The Swedish bindings got the lowest score of the lot in the forest category, btw, although they too were found to be ok. The author was Jouni L, who's also found in some of the old pics above. |
