Twizz 2010/2011

Figured it was time to start a thread for the season. Since I no longer live with KevyWevy in the Ski Haus, I'm not going to keep adding to our Ski Haus journal thread. Here's my own
The first skis I'm making this year are the Crabby Sticks. I'm going for a stiff-ish all mountain ski, since all the skis I've made so far have been super soft. Want to try something different.
They are 170cm length, 118/85/105 I think? (can't remember the exact numbers without having the CAD file in front of me). I am using bamboo flooring for the cores, with bamboo sidewalls. They also have threaded inserts for my Look bindings.
Now here's the cool part. I am doing two identical pairs at the same time. One pair will be a traditional wet layup with 22oz triax fiberglass. For the other pair I am using the pre-cured pre-tensioned fiberglass/carbon fiber from Snowboard Materials. Hypothetically these skis should be stiffer and lighter weight than the wet layup... but I won't know until they're out of the press!
I have a few more edges to bend this week, but then everything is ready to go, just waiting for the sublimated top sheets to arrive. The bases are cut, cores are profiled, inserts are epoxied into the cores.
I also made a new mold. The tip/tail molds are normal vertical ribs bolted together. For the camber section I used a single piece of 1" MDF, and used the planer to cut the camber shape just as you do for profiling cores. It worked perfect, and I have a perfectly smooth and flat (laterally) camber section. Now if I want to make shorter or longer skis, I just make new camber sections and swap those out!
That's all for now, hopefully I'll get the top sheets soon and I can press all four skis in a day.
