Did you try thinning the epoxy you put on the base? I know that there are products that you can use to solidify rotten wood that are epoxy thinned down with acetone so the wood soaks it up. I think thats how they made the hard "lignostone" edges on nordic skis.

As I recall, the amount of titanium in Titanal is <0. which might be why it's more commonly used in ski manufacture, as opposed to titanium. coefficients of thermal expansion for CF and FG composites in Table 1: http://www.performancecomposites.com/graphitedesignguide.pdf note the units of in/in-F,...

I think the issues of metal lamination bonding might be titanium specific. http://www.engineeringtoolbox.com/linear-expansion-coefficients-d_95.html This chart doesn't exactly show the coefficient of thermal expansion for glass reinforced epoxy, but it shows epoxy at 50x10-6 m/m K, lower than most p...

I found some SEM micrographs of waxed and unwaxed ski bases here: http://www.escnordic.org.uk/myths/pores.htm I assume these might be similar to the ones formerly shown in this thread. A note on base structure: the purpose of base structure is not to reduce sliding friction, it's to allow water to &...

I've been thinking of doing a race ski at some point, and one thing I've noticed is that most commercial race skis have two layers of aluminum, one above, one below the core.

I've been reading through the guides, forums, and such, and there's one thing I just don't understand: why does everybody vertically laminate their cores? My understanding is that you want a ski to have longitudinal and torsional stiffness. Laminations provide this by allowing you to put together sh...

In terms of materials and construction, how are a pair of, for example, GS race skis unique? I assume that there is some kind of super- secret material and quasi magical design considerations that make them fast (and expensive) however, I am just wondering what it would take to make a pair of skis t...
