honeycomb
Hi!
have someone tried honeycomb for tips and tails? Lot s of ski brands use this for reducing swing weight.
I d like to try it but I am not sure how about bonding that oily material...
I can make some bonding tests but this will not properly simulate skiing and suitable tension by skiing...
any hints? Thanks :)

No, oily is wrong word for that meening. Difficuilt is to use only as much glue as necessary for bonding.... If more, there is no gain from using honeycomb material. It seems like there is only way in prepregs to succesfuly use honeycomb for reducing weight... And it is a bit impossible for me now :( maybe i ll try to reduce swing weight with maximal shortening of tip and tail spacers... There would be more of wood with lower density and plastic would cover only for example last 3 cm (in contrary to present 10-15 cm) ....

I experimented with some nomex honeycomb a few years ago, but never followed through with any ski builds. We had a thread on here somewhere about it, where somebody included a link to an interesting paper on how to get good bonding results with honeycomb. I think you're right, that prepreg is the best way to do it. It's hard to keep from just filling the honeycomb with resin with a normal wet layup.
For wet layups, foam is probably the easier way to save weight.

I didn't want to hijack this thread, but didn't think it was worth posting a new one for my question. I'm going to build a board with Nomex Honeycomb in it like this
I will rout out the spots in the core and lay fiberglass tissue over it just to seal it before final layup so epoxy doesn't seep in. I was wondering if this pattern would affect performance in any negative way and if I should use Aramid paper honeycomb or aluminum. Any help would be great!

My two cents: I'd try to round the beginning and end of the honeycomb portions so the board doesn't have easy points to break on. try to make them ovals or diamond shaped.
another idea is to use paulownia and channel it like fischer skis do for the Hannibal and race ski with a biscuit joiner.
