I haven't heard anything about wood/carbon delam issues, but it could make sense in my head. I don't think rubber would help, just prep the surface better. End-grain balsa sheets would probably be the easiest thing to make a carbon ski from first. With the stiffness of a carbon laminate I wouldn't t...

No, not all resin is epoxy, there are also vinylester and polyester resins. There are significant differences, Google describes it better than I can. but... I think it matters who your supplier is, are you paying wholesale or retail? I also work for a marine company. We get MAS quarts for $14 and We...

stupid question:

kam S leang wrote:- inserts: height = 5-7mm

if the inserts are only 7mm tall (add 2-3mm for the counterbore?) how do they make it through a 12mm core?

How thick is the damping rubber that is often used.
I've got rolls of .055" (Dina h?).
Probably have to use a few plies for tip spacers, not sure how that will work....

I'm in the market Kelvin, as I plan to start tooling for my first pair this month, but I'm going to need other stuff too (P-tex, inserts, topsheets), so I'm probably going to order from the snowboard site.

Looking through this, and other sites, a home user can get an idea of standard dimensions of stuff. But it's not laid out nicely anywhere to get a design going before you purchase parts, or while parts are on order. Perhaps we could do this here? I'm thinking stuff like: -the cross-sectional size of...

Got some more info from the nice people at Crown Plastics, if anyone cares, probably way more info than most home builders want but..... UHMWPE has a melt temperature of around 280F. Working in the 250F range should not result in much, if any, dimensional change in the material. As you approach and ...

I'm really interested in asymmetric sidecut skis, seems to make sense, but it would also seem that it's easier to f-it up by choosing bad dimensions than it is to get it right. Or the other way to look at is, before you go messing with a few hundred years of perfectly usable ski design you better ha...

For those who care, Durasurf has told me that 250F at 80psi for 1+hour will not harm their P-tex. Interesting that this is a HUGE difference from the Nordic-racing-nerds who tell me that passing a 125F tuning iron too slowly over the base while waxing can "burn" your P-tex and affect perfo...

Thanks Kam, I'll drop them an email. I work for a company that makes pre-preg carbon stuff. I had a good idea the other day for how I can tool up up a ski that will enable even an imbicile like me to laminate it. We'll see if it works. I'll keep you posted. btw, so glad I found this site. It rocks, ...

How hot can P-tex get?
I've got pre-preg materials and an autoclave at my disposal. The pre-preg materials require a cook of ~250F for 1 hour in the autoclave. Will this damage the P-tex?
