pamarine,sorry it took so long getting back here,when we started building snowboards back in the early 90s there was no info available at all and no company in the world who could build a board that would last a season without falling apart,it took everyone years to reach the stage they are at now with no sharing of technology,very few are now manufactured in the USA.Im sorry i dont have any links as ive been out of the industry for a decade but when i look at them in the shops im struck by how they havnt changed at all since we ceased production except for more basic logo style graphics to reduce costs.I did a google search a few weeks ago and found a place that will show you how its done(for a cost of course)What i can tell you is that i learned a lot more about sticking difficult to bond materials together in that 7 year period than in my 35 years or so as a boatbuilder.
