minor issues that need help
Posted: Wed Mar 08, 2006 11:44 pm
so, we pressed pair number two a few weeks ago and had a lot more success than our first pair, but still a few problems.
1. We pressed our skis for 26hours at a declining pressure of 40-25psi overnight. We pulled the skis which immediately lost almost all camber, and about half of the tip and tail rise. I am stumped why this happened, all I can come up with is that it is the epoxy. we used west systems 206A and 205A just like you guys, although the temp was around 40* by morning (the epoxy should cure in 10hrs or so at 32 though? ? ? ?) any ideas?
2. Skis were SUPER SOFT---understandable since we used 4oz glass and hemlock cores (unlaminated)---these were our lower benchmark skis to see what a minimum amount would ski like (min. glass, soft wood, two layers glass per ski, nothing fancy) my question here is this: wil doubling mass of glass double stiffness? (ie two layers of 8oz glass?)
3. BIGGEST PROBLEM! we mounted some alpine bindings (look p 8.0 demo). The toe piece ripped out after one semi-aggressive run in th BC in soft snow, stripped right out of the wood. Some ski shops told me ALL skis use metal sheets for the binding to screw into, i dont believe them, what do you recommend? (thicker/more layers of glass under-foot, perhaps some glass matte?)
4. Bases were concave and convex all over!, I took them to a ski shop, and in order to get them flat, they took off so much base that it was non-existent in some areas---what cause such a thing? (epoxy buildup, glass crinkles, MDF ribs?????)
Thanks for any help
