:: View topic - rubber tips

anyone use rubber tips? Similar to rossignol scratch and karhu skis. any problems and/or recommendations?

Kelvin and i were debating about rubber tips at some point, in particular, their effect on ski durability and performance. it's probably true that they will help somewhat, especially to reduce the effects of shearing between layers to prevent/minimize delamination. adding rubber elsewhere on the ski may improve damping.

i've looked in the McMaster catalog (http://www.mcmaster.com/, type in "rubber" in the find box). they sell sheets. we haven't ordered any yet, but at some point we'll give it a try.

the demo on the Karhu factory video at telemarktips is exactly the same the scratch demo in Oslo. Basically, you can stand on the tips and bend them in almost any direction and the tips will snap back into position with no damage to the ski. Point is it seems like a good idea I was just wondering about the execution?

would any type of rubber work?

scratch demo in Oslo? What's that?

A sales guy in Oslo Sportslager (IMHO a good ski shop) stood on the tip of a scratch fs to show durable the rubber tips are. The same demo can be seen in the visit to the karhu factory video on telemarktips.

Just curious since I live in Oslo and frequently visit sportslageret. Seen the video, quite impressive.

er du norsk?

Hei Endre

Jeg er engelsk(and that's the limit of my Norsk), but I'll be in Oslo tele boot buying in November if you fancy meeting up for a beer and ski building chat.

Definately! feels like I am the only person doing this here. Mail me when you come over, I'll give you a private factory tour.

thanks - looking forward to it

Is the top coating stretched over the rubber tips on the new Rossignol? Dosen't it brake if it beds?

btw, my first ski press is son finishd, pictures are coming.

The ski's were last years scratch fs and bending didn't seem to harm the top sheet. The skis didn't seem to be a cap construction, i.e., not like a salomon 1080 ski, but I've never seen the innards of a rossignol ski. If anyone's got an old pair that they feel like cutting up to see how the tips are made please feel free to share.

there new skis have the same thing i think http://newschoolers.com/ns3/web/content/pagetemplate.php?name=siavegas2006&page=rossignol check the 4th pic doen it does from wood to a rubber looking stuff

they use a rubber tip spacer, which i think is a great idea becaues it dampnes the tips alot making a soft ski alot more stable without taking away from its pop

ninthward has skis with a bamboo stringer instead of carbon but wiuld bamboo give you the flex you need? if so how thick?

Hi,

I stumbled across this website whilst doing some research for a design project at my university in the UK (Bristol Univeristy).

For our project we are looking to construct a composite bow arm for a crossbow. This may sound a little strange, however a ski has almost exactly the properties we are looking for (light and good flexibility) and are therefore potentially looking to construct our own cross bow arm (ski!).

As we are limited by time and budget constraints it is likely that we will get only 1 or 2 attempts to form our ski before the project deadline. Our access to equipment is good (being at a univeristy) and I have had some experience of working with composites/epoxy resin.

I was wondering (bearing in mind we will need to construct the press/mold also) how likely it is that we would have a useable ski after only 1 or 2 attempts at the process. We have no real interest in the end aesthetics, but are looking for good flexibility. How successful was your first attempt(s) at home made ski's?

Many thanks

the problems with skis are getting the edges correct, topsheet nice, base flat etc. woithout those components, probably perfect at seccond attempt..
