New sticks: The piste less traveled
Posted: Tue Oct 28, 2008 8:38 pm
I wanted to make a stiffer, version of a ski I previously built. I am hoping for a ski I can use in the frontcountry as well backcountry. I'm not aiming for anything featherweight but not too burly either. I designed the skis so they would take my 100mm skins. Aside from being a little too soft in the tail the ski was a good shape but I had had some problems with during lay-up. The dimensions are 185cm with a 22.5-25m turning radius and just over 100mm underfoot. The core is 11mm underfoot and tapers out to 2mm at the tip and tail. I used a planer crib like some other people have been using. It works far better than the router jig I made originally. I have fewer tear-outs and it takes a fraction the time. The layup isn't anything fancy. I used pine/fir core and wood sidewalls with triaxial fiberglass layers. I added a section of twenty oz biaxial fiberglass with a 3/4oz mat to reinforce the binding area. It's brand name is Knytex or something very similar.
I was in such a rush to actually get the skis in the press I think I may have shot myself in the foot. First off I forgot to cut my tip spacers. I was just about to slap down the cores when I realized what I was missing. Then i misplaced my topsheet material, after a few minutes of searching I found it. The ordeal was a lesson in patience and foresight I don't want to repeat. On a better note, I think I got everything together before my epoxy started to go off. I am using a pretty an epoxy that will set at room temp but slow unless it is heated.
cutting the form.
Laminated core
Profiled core
I'll everything out of the press tomorrow and post some more pictures as soon as I clean them up.
