Just trying to curb the veneer. I did a few small tests. 1 Varnished veneer with protective film; 2 Veneer with no varnish and protective film; 3 Veneer with extra epoxy on the top; 4 Veneer with just protective film. I have used Henesport 150 spray coat for varnishing. The best aesthetic result goe...

Isosport says that they use paper and phenol resin. I guess they press paper impregnated with resin.
Definitely it is horror for cutting tools) beside diamond cutting))

That might be the reason why slalom and giant snowboards have such sidewalls.
But may be it is possible to make sidewalls made of phenolic resin pouring it into a mold like epoxy resin. I don't know, only guess.

Actually snowboard was broken on two halves and I used pliers to get piece of the sidewall. The result you see on the picture.
Thanks guys, you eased my search for truth.
Have anybody worked with phenolic resins before?

One my friend gave me broken snowboard for giant style. The company that manufactures such snowboards is called OneEdge Style. I did some analysis of snowboard insides and was puzzled which material this company use for sidewalls. I was surprised that they were made of wood. I found out that it is w...

We cure under the temperature.
I would like more or less calculate stiffness before layup.
Also arrangement plays big role (length and width of carbon strips)

Gilo, we are experimenting with selcom products. We are going to experiment with 14 oz fiberglass reinforcing it with 7 oz carbon fiber. Also we will use paulownia birch core for tests. I read that in order to achieve the desired result (I mean desired rocker of camber or whatever) the fibers have t...

Fiberglass and carbon arrangement

Hello everybody summertime, in addition to the repair of the premises this really hot summer we are going to experiment with carbon. I have found a few topics about carbon and found them really useful. But still got some questions. Stop me if I've touched the previously mentioned topic. Let me start...

Have anybody tested their skies or snowboards on destruction under the pressure? It is interesting how many kilos one ski or one snowboard could take? Using acquaintances in the Research University we did a few experiments to test theoretical and practical calculations. http://s15.postimg.org/4pbmuu...

Apart of UV inks, we have also experimented with sublimation. Yes, running base is hard to sublimate (too high temp - melting, too low - picture won't be bright or inks won't even move to the base) , but it is possible, just right temperature regime, pressure and cooling. Now we are working on press...

Definitely there are inks that might work good. But this way is too energy and time consuming, that is why now we work hard on our sublimation press. Guess, soon I will show some pictures of it, and the result of printing as well.

We did a few boards made of spruce and pine.
Pine is definitely heavier, but mechanical properties are approximately the same, pine is a bit stiffer.
