ok, that was just guesswork...i got the numbers of the single board kit (1kg) sold at snowboardmaterials. we havent pressed any boards yet, so i'll update those figures by the end of next week. but 330g sounds good...that'd cut the costs in half! (we'll be just using one layer of 21oz glass plus the...

assuming we use about 750grams of epoxy for one snowboard, we get 20 boards out of a 15kg package, which costs us about 260 EUR incl. shipping (200,- without shipping...mind that we bought quite a bit of fibreglass at the same time, so i guess shipping for just the epoxy would be cheaper). so the ep...

same thing with the sicomin...but a single hotplate and some water in our shop take care of it (also eliminates all the bubbles!).

we're using Sicomin SR8500 resin with SZ8525 hardener. heated cures at 180F in about 20min.

take a look at my last post in our journal: http://www.skibuilders.com/phpBB2/viewtopic.php?t=2044

i'll do an in depth description as soon as i find the time to do so...one thing i can tell you already is: they work! tested them on a ski and they heated the press to 180F in no time.

i don't think the pressure would be a problem, but still the wattage is far too little.
we're using a pretty similar approach, but the heating elements we use are made for industrial applications, so they have enough power.

that printer should be able to print a ski lenght at once no problem!

like he said he had it plotted. that means it was either printed by a large laser or inkjet printer. most copy shops have one of these to print large photos and most of them also offer an option to print with uv-resistant inks if you want to be on the safe side. still, using your printer at work sho...

did the paper turn a lot darker under the epoxy? im thinking about doing the same.

yep, the 0/+45/-45 is the stuff you want to use.

http://www.boardbuildingsupply.eu/index ... 03ff6e9934 has them.
http://members.aon.at/tds/eng/mainmenu.html makes them too.

any plans on getting a distributor for europe?

thank you twizzstyle! will try the hotglue.

edit: just a thought, wouldnt it be good to put glue all around the edges? it could prevent epoxy from getting on the base.

thanks guys!
@hugo: the 100°C was just a figure...thats what we can go max. will be pressing between 70-80°C.
doesn't the tape leave imprints on the base?

sry if this question has already been asked, but i couldn't find an answer via the search function.

how do i prevent the base material from shifting in the aluminum casette in a heated press?
i guess hotglue or double sided tape wouldn't work too well at 100°C.
