 Poster: A snowHead
|
Hi All,
I was wondering if it's worth bothering with ptex repairs on a set of skis mainly used on a dry slope?
I've repaired a few times myself using a ptex candle, fell out first day of use. I then had a repair done by a local specialist (using skimender), that's gone now and the patch of base that was repaired has got worse since. Annoyingly they said at the time it's 100% been caused by bad maintenance at the dry slope (where wire is used to attach panels together it hasn't been pushed down, creating a few slits through the base material)
It's right by edge of the ski and has now exposed a few mm past the edge for a length of maybe 10-15cm. I've tried to keep on top of it with regular dry slope waxing but it seems no matter what is done, repairs will never last.
Have I just had a bad repair done, or is it correct to expect no repair to hold up on a dryslope with the heat generated? The skis are retired now as my son has moved up a size, but I don't want to get another repair done for it to fall out on the next person.

An epoxy resin like araldite works wonderfully.

Well, the person's real but it's just a made up name, see?

No experience of repairs for dry slope use, but araldite, in its various forms, doesn't cope very well with freezing, and larger areas of it are prone to cracking up if there's any movement around the repair.
Repairs to base damage right on the edge are inevitably destined to fail again and again, IME, especially on an older ski that's been ground down over multiple services, and the effort and time invested may be better spent elsewhere, provided of course that you can afford to replace them. But really, once they get to that stage it's often a false economy to try and keep them going.
Oh, and also IME shop repairs are no more likely to succeed than home ones, and you really are looking at throwing quite a lot of money at something that will never be as good as before if you go down that route.
I guess the equation might be different for UK dry slope use though...

@Chaletbeauroc, very little dryslope skiing takes place in sub zero temperature. In fact it is the heat of friction and the fact that it often done during the summer that makes ptex fail. It is also very unusual for the base to be ground; the edges are usually filed away long before any base grind is contemplated.

Anyway, snowHeads is much more fun if you do.

@johnE, Yes, the temperature thing was clear, just making the point that failure of araldite for normal ski repairs may be due to that, but also may be the vibration/movement also mentioned.
But I'm puzzled by what you say about the edges. Do you mean you're filing them from the side? Of course one sharpens the edge from both angles, but generally any actual edge filing (I do) is on the base of the edge, and it would lead to a very odd shaped ski if you somehow managed to do that without also grinding the base surface, such that the edge would not actually touch if you were to put it on a flat surface.
Is this actually a thing for dry slopes?

Yes, almost all edge sharpening is on the side edge. Filing of the base edge is mainly to remove the burr. I sharpen the edges after almost every session and the base of the edge will get a quick stroke or two, no more.
My snow skis have done close to 100 days and I've never base ground them. Do people grind their skis frequently? I follow more or less the same procedures for the snow skis as I do for the dryslope ones except less frequently and with different wax and use a ptex candle

Oh yes we do.. but for plastic we want our skis really really really sharp --- much sharper than snow. To give you an idea my race skis will get sharpened after an hour of use.
@damanpunk, Yes for expoxy -- or a patch. Ptex candle or similar (what you would do for snow) just won't stay in. I would swap skis around so the affected area is the outside edge.

I have found using metal grip base repair wire seems to work better than ptex.

? When repairing skis in a shop in Banff (prone to -40C regularily) we used slow (overnight) cure araldite with no problem to glue base patches and edge repairs in place!
