A while ago, we did this idea of vertical laminates between the core stringers and it worked out fairly well. For the process, we essentially did a pre-cure of the carbon. We put 12 K triax Carbon in the press with some epoxy and just cured a big sheet of it, then cut it up on the table saw and lami...

Anniversary
Just wanted to point out that I noticed that today is the 10 year anniversary of this forum. The user "administrator" was registered on December 11, 2004. In that time, 44881 articles have been posted. Nice job everyone.

Completely out of curiosity, has anybody ever looked into using Australian Buloke for sidewalls? Possibly some of you guys down under? In the US, it seems you can only buy it in chunks big enough for knife handles. I would imagine that full sidewalls would be hella expensive and you would need to re...

Interesting. I tried putting one of the cores through the planer once, but it just made a terrifying noise, popped the circuit breaker, burnt the cores, and chipped and dulled the blades significantly.That might have been because of the heavy weight of the fiberglass, though. It could be worth anoth...

Dtrain, funny you say that now because profiling those cores was one of the biggest pains in the ass I've ever experienced. With the fiberglass, I was afraid it would break our planer or just go through like 4 sets of blades. So, I ended up using about 8 36 grit sanding belts on the belt sander per ...

Didn't really think about how different the homemade horizontal composite ones should have been. Strange. There must have been some problem with epoxy or hardener. We may have done uneven ratios or it might have been old. I'll look into that. I'm not sure what weight uni Icelantic uses. Like I said ...

MM, Thanks for the questions. As for the first thing about isotropic-ness, that is actually a mistake. Totally screwed that up, but thanks for pointing it out. I left out a lot of things because I had a certain word limit for each category. I really wanted to include more on core thickness and desig...

Vertically Laminated Composites
So about two years ago, I posted an idea of laminating the composites vertically in between the core stringers. A few of you said you had always wanted to do it. Well, I finally did it with 22oz Triaxial Fiberglass. Also, since I am 16, I was eligible for signing up for the Google Science Fair. It i...

Thanks man. 1. When we epoxied the fabric to the base, essentially what I did was put a piece of sheet metal above and below the plastic, then just put everything in the garage I could find that was about the same length and was heavy on top of it all (probably ended up being 250 lbs in all). If I w...

So after 15 days on the skis I did this with and one crash going 60 mph in which most of the energy was focused directly on the edge, these skis are still holding together quite nicely. It seems as if this experiment has miraculously worked. By the way, the last time I posted on this particular thre...

Is the thickest part of your core at the camber point? Yes. Or at least it is supposed to be. We ran out of belts for the belt sander part of the way through the final stages of profiling. So, near the tail, it's about .4 mm thicker than we designed it to be. At camber point, the profile is pretty ...
