I do think it is a little bit obvious that not applying epoxy to an areas will leave dry spots. If this the sort of issue you are struggling with, I would read through Tony's posts again. Contacting him directly is probably off the cards, which is a shame because I now have a qualitatively different laminate reflected in a much tighter fibre to resin ratio.

care to elaborate on the qualitative differences and how you achieve these different ratios?

The approach is called hot melt processing, the quantitative differences ... I sleep better.

I really appreciate the intentional obtuseness or cryptic responses.
I continue to assume you are not a native English speaker.

Personally I believe you weaken any epoxy leaving it under heat past the time it's set...if this is what you're talking about. It gets brittle.

I have read every post in this thread. I know nothing... let me start with that so nobody thinks I am an expert...lol...

Every one of you has talked about the Forrest products and heating the mold... or at least that's the short of it...

What about the West Systems "cold" epoxy set-up?

Is this just crap or can I make a good ski with it?

I am just starting out and want to know... from all you experts here... well, at least from the people who have made a ski before with both heated and not heated epoxies.

Thanks!

this has been discussed many times on here:

Yes you can use West System epoxy. I have used it at room temp as well as QCM/Forrest epoxy at room temp. It just takes longer to cure. Heat makes it cure faster... and stronger I believe.

The West system took a long long time to cure. It stayed rubbery for a couple days but finally hardened. Not sure if this is a typical characteristic of West or if it was measured/mixed improperly. I was helping out a fellow builder who used West because it was easily available. It's the only experience I've had with West so far.

To make it easy on your self, use what others have used. I did a search in the forum tonight on resinreaserch (another manufacturer of epoxy) and that lead me to at least 1/2 dozen other epoxy products.

West works fine, don't let anybody tell you different.
It's just stupid expensive for what it is.

The nice thing about west systems is you can literally find it anywhere.
I've got a couple pairs of skis built with west that have +100 days on them

I know a few people have had good success with resin research.

Prices include shipping to cont. US.
I will probably give this one a try next after the QCM ( now forrest ) is gone.
My buddy JV is using it and it looks crystal clear.
I'll be looking at 2070/3100s. Should do well in a room temp cure and thin enough to wet out easily.
**(I have yet to try it so don't point fingers if it doesn't work for you)**

All epoxy will benefit from some heat, I have an old electric blanket ( like on the bed at grandmas ) works OK to help with initial and post cure heat.

I can affirm this exact combination of Resin Research products. Works perfectly for ski building in my heated press. Holds up very well on the mountain, so far I don't notice any difference in the durability compaired with QCM epoxy.
