I cut strips of balsa wood, then I glued with polyurethane glue, flexural stiffness is expected to increase.

Yes, of course, I already know these skis but I'm thinking to something better, lighter, more efficient and faster to use.

I found balsa wood. Very light, not sure about strength.

I already use a pair of short skis and they work ;) trust me, I cut a pair of longer ski-mountaineering skis but with dynafit bindings they weight about 1 kg. Short skis are more efficient than snowshoes, you make them slide ;) Having less weight on feet is far better than less weight on back, so li...

Hi, I would like to build a pair of short skis (110 cm) only for uphill with skins under skis. I think that the features have to be: As light as possible without sidecut with some camber under foot 65 mm large to fit narrow race skins with edges without base since their will be always the skin I've ...

ok !

what is more important to preserve the flex and the camber in a pair of skis for many years?
the wood used or fiber? or something else like the whole process of making?
