Twizz--are you bonding the honeycomb directly to the core at all? Or, are you just bonding it to the veneer and then the veneer to the core? If you wrapped the entire honeycomb piece in a film adhesive before you inserted it into the core you would gain a lot more contact area for bonding. If I unde...

I've brought my base material (with edges attached) into the garage from inside, taped them to my aluminum cassette (which was freezing), and watched the bases warp so much the edges pulled away. This took about 60 seconds.

I've just found local guy that will CNC cut my bases. $30 for a the first pair of a certain shape, $15 for the next pair of the same shape. The extra $15 is for him making the cut file. Seems pretty reasonable. Why not just get a template cut for $30? You would save a bunch of money. You can still ...

Thinking of building a vacuum table now. You still have to be very careful with the vacuum table. I have found that it's almost easier to suck the material down crooked using vacuum. It almost pulls too hard on the material and can easily twist it. It really helps to let the base material relax and...

If you have access to some honeycomb core, you probably have access to some film adhesive. Why use the bamboo veneer when you can use the real thing? I would think it would bond to the honeycomb way better and simplify your math calculations.

Thanks for sharing the Epic Plank story. I'm pretty jealous as I've been wanting to send it myself for a few years, but here I am still working for the man. It gets harder and harder passing on a dependable pay check, ya know. I realized that even though I really love building skis, I hate selling s...

Re: Combining different CRP/GRP cloths

Hi everyone, Do you think this would work? Would it be better to have the higher number ply of cloth on top or underneath the core? It's not about the # of ply, it's about the aerial weight of the fabric and the orientation of the fibers. There's really a number of different ways of essentially end...

Thanks for all the updates on your progress throughout the season. I'm wondering how many pairs of skis you built this season. I'm guessing quite a few because of your "production" speak. Keep up the good work!

So are you saying you have 58cm under-foot of essentially a flat profile of 10.5mm thick? If this is the case, these will literally ski like planks. I have around 6-8" of flat in my profile at 11mm thick and they feel very stiff underfoot. Don't be afraid to go thinner in the tips. You can have...

Re: Heat Cure

Most high-performance composites are built with no more pressure than one atmosphere of vacuum. So something between 14 psig and 30 psig. If it is good enough for most parts on a Boeing 787 and the F34 fighter, it will make great skis. :D So I'm really not trying to stir the pot here, but sorry OAC...

The Cali-bamboo is O.K. in my opinion. I have used Terregrin bamboo before and it seemed to be a bit better overall. The Cali stuff wasn't really all that consistent when I was profiling the cores (planer crib method). Some cores went through the planer super easy and some barely at all. It was stra...

Ya, the footage is from the Nordica factory--full on production. At one point he checks the camber with a little gauge of some sort. He must be tweaking them into tolerance. Here's another video that makes you think WTF? Is that some sort of binding mount plate? http://www.youtube.com/watch?v=F3Sttq...

How the Pro's do camber

My friend gave me a Go-Pro camera he found this summer at Snowbird after the snow melted. The memory card was full of videos from the Nordica factory. Almost all the vids were horrible and didn't really show much, but this one was pretty interesting. http://www.youtube.com/watch?v=vgPx_ogKOZA&fe...

The skis you listed actually are all quite different. For example, I think the Lines are half as stiff under foot as the JJ's. The JJ's have a super short sidecut compared to the Blogs ect. You need to think about the aspects of the design that are important to you and then try to design accordingly...

I have the most success using Bosch T101BF blades in my jig saw. I can usually trim out a complete pair of skis with just one such blade, well sometimes one and a half blades. ;) These are 10 TPI, "progressive", Bi-metal blades. I've tried others, including T101B and could only make it ab...
