How are you profiling your honeycomb? What are you glueing them together with?
What are you using on your rails?
Are you vacuum bagging or just wet lay up?
I was thinking of using Nida core but can't profile that.

I just received a Nomex honeycomb from a well known kiter here who kindly offered it (thank you!).

It is about 4mm thick, and I never ever even seen it in person. It's incredibly light and strong. It also bends, since got it rolled.

As I see it the only viable option to work with Nomex is a prepreg carbon with a vac. Would be a bitc. to even wet it properly, and bonding two sheets is a no mean feat.

Hence, for me, wood all the way for the boards. For a HF, it's got some merits.

Sanding with a flat surface
What are you glueing them together with?
I used structural epoxy adhesive
What are you using on your rails?
Epoxy with carbon fiber powder
Are you vacuum bagging or just wet lay up?
I use wet lay up for the bottom, vacuum bagging for the top

I don't know Nida, I have to search some info

Are you using spot bond?
Also company I'm using for materials near me is LBI fiberglass.
Here is a link

I don't remember was something from 3M

What you said it's true, a lot of trouble without a great gain. For sure a balsa core give you the maximum of performance and the minimun of troubles.... but sometime we have to try something different :D

One time I used a particular selection of balsa, balsa light, perfect strips, 10% weight less than usual balsa... very good :thumb: But isn't no more available :angryfire:

I put this balsa as a core in this board

About NIDA.... it's quite difficult to talk about something that I've never used or touched, but it seem not so suitable for kiteboard. You could try to sanding the top sheet and to try to reduce the thikness but .... I don't think it's so easy.

Very nice to watch:) Thanks! Reminds me of my first (2nd) build tested on Bali :) Similar environment.

Do tell us more about your split construction. What did you use for a Stainless steel inserts? I also like your stencil work, how do you do it?
Sorry for hijacking a thread :)

PS

This Nida Core looks quite rigid, and only 2by4 ft for a decent money...Interesting tho.

McMaster Carr is always a good place to get stuff.
I stopped at LBI yesterday to buy some supplies for a boat project I'm working on and they gave me some nida core to play with. (Spent a lot of $$ and a regular customer) I got 3 chunks. 2 are 3/8 1'x4' and the 1/2" is 2x4. I also have some 1/2" 8lb core foam to play with. Thinking of making a board with this stuff as soon an I'm able to free some time up.
Read that as new baby ready to be born any moment! But as soon as I can I'll get pics up.

Wile I sit in the hospital and dream of warm winds and new project. I hope someone gets to rip it up on nys day for me!!
