for Austria, I just found this :
http://www.peakleaders.com/austriaskiinstructorcourse.asp That's interesting, you'd need German of course for that. |

That's a bit misleading, CSIA level 1's can't really teach much outside of Canada so they're no more or less able to teach in across Europe than a BASI 1 would be. You need a CSIA level 3, i.e. ISIA, to be an instructor in Europe in general terms without being too specific. The training paths are a little different so it's hard to make comparisons until that ISIA level. |

To start training, that's not such a high standard. The problem for a lot of skiers is that they're locked into a mindset where they're not taking lessons and reinforcing some bad habits, it's harder to unlearn some bad habits than to learn good ones from the start. As for working in Austria, that's harder than anywhere in North America but not impossible. It makes sense then to qualify under the BASI system to work across Europe, it's not that you can't work in Europe with an American or Canadian qualification it's just not the simplest route. There's a lot of gap courses around, a couple of training providers are : http://www.icesi.org/ http://www.skiacademyswitzerland.com/ Get a day or two next season with a BASI instructor and they'll give you some pointers about your skiing and how to achieve your goal. Some more info' at the BASI site : http://www.basi.org.uk/ |

Providing you reset them then I can't see any harm at all, it's just I see no beneficial effect so it's as much of a ritual as anything, you might as well as smear the bindings with garlic :D (it's going to turn out that garlic has some benefit I'm unaware of of course now) |

That's obviously unfortunate and you're the victim of someone else's stupidity in that. There's a problem in a lot of ski shops and hire shops that the staff really don't have any special knowledge at all, it's a skiing oddity, we know the lad in Dixons or PC World isn't likely to be offering good advice necessarily but then we go next door to the local ski store and behave as though something's altered. That's not to say there's not a lot of fantastic specialist stores run by real enthusiasts who have a lot of knowledge of course, it's just in the end in many cases, you've got a guy who works in a shop. It's not just that I've had a near miss with loose skis nearly hitting me that winds me up, it's the mentality of the people that do it that really makes me mad. Because it has no apparent downside for them then there's not a split second of thought about if it might be a problem for anyone else. |

well put, I was going to ask the same question. Equally well put was the succinct definition of what fatigue is, better than I'd manage for sure :D The purpose of SN curves is help engineers select suitable materials for applications is it not? Which is why given it's well understood I struggle to understand why binding might contain the wrong springs. In terms of fatigue, it struck me today driving down the hill, mind wandering, that corrosion would be another problem, I was particularly thinking of the effect of salt from the road if you're chucking the skis on the roof without any covering. Would that be right?
but hard to measure as Dave said, below the threshold that the binding test machine can manage from my limited field testing
ah, a direct hit on one of my many pet peeves :D I'm seriously wound up by the people who have their bindings set too low, after twice narrowly missing being hit in the head by loose skis and having one of the owners explain to me how is was "safer" to have the bindings low :D |
|
I only just noticed that, that's totally untrue and quite easy to test, any store with the suitable equipment can verify the datum force is still able to open a binding at any given DIN setting. Those of us who have our bindings checked regularly know this, in fact I've computer printouts somewhere of the forces on my bindings over time which remain just the same even though I ski at the higher DIN settings. Sorry, but the idea that springs degrade when used inside their normal operating ranges is just plain untrue, it's bad mechanics, machines all over the world would be failing all the time if that were true. Urban myths die hard I'm afraid ) |
|
and they're wrong I'm afraid, just repeating an old story.
The first point isn't relevant, elastic isn't metal. The second point is just wrong, forces below the static yield strength will not deform the the spring, that's the point in fact, if the forces exceed static yield strength or there's cyclic loading in which case the spring is unsuitable for the application. And your third point is right on the money, that's exactly why people mess with their bindings :D |
