I think an interesting all conditions upgrade to the 19 or 21 ounce triax might be like a layer of 4.7 ounce HS (high strength, not high modulus) Textreme carbon at 45/45 or 0/90 next to the core and 6 ounce unidirectional S glass or basalt lengthwise outside of that. Still might explode, but that's...

I've made heaps of powder boards in all carbon, but usually with stiff cores and tons of rocker. I love them. But I pick my days here in Utah, pretty much just riding fantastic backcountry conditions. On a normal profile core one problem that you may encounter is compressive failure of carbon on the...

Dyed veneers shouldn't be too hard to find. I have some 36" long pieces from here http://www.dyed-veneer.com/dyed_veneers.aspx haven't used them yet but they look very nice, I have the blue, light blue and blue green colors, and some black to make pinlines. the grain on the koto wood looks grea...

FWIW, I agree with SA. If you are trying to lose weight with a carbon/glass layup and not get an overly stiff result, I would use carbon for your torsional stiffness and fiberglass in the O degree or longitudinal axis. You could cut your uni carbon in patches and lay it in on the +- 45 angles. Thin ...

Wvmtbiker- To answer your questions a bit back. I only do 3/4 edges, so just an inch or two beyond the contact points. Bends are so easy you could do with hands, I use the standard modified end cutters. I don't heat treat the metal at all. I superglue edges to base then bend over different radius PV...

I vacuum press now only. A general concept for vacuum I think is to have all your pieces fit as perfect as you can have them and don't count on a lot of excess resin being squished out the same way as a pneumatic press. Try to use laminates that lay flat. spread resin on your fabric on a separate ta...

Thanks, Yeah I have been getting mixed messages on the forum about whether its expansion or contraction of glass that makes glassed boards go out of flat sometimes. Time for me to just have a go. I hear ya on fun in the shop versus building a side business. I think I have loved the tax benefits the ...

Thanks for your reply Dtrain and enjoy that snow up there!. Essentially dry down here, but enough to facet. I wrote my last message wrong. So the take away is that the single side (the base) that has the 90 degree or cross board glass will end up expanded and make the base convex. Could this be a re...

DTrain, he looks stoked, kids are awesome. I am wondering one thing though. I would have thought that since you only had glass going across the board on the base in the 90 degree orientation, that the base glass would have expanded with heat, then contracted after heating and curing and would pull t...

Ok, so it is standard 8210 topsheet with a transparent printing on it, done the same way an opaque topsheet would be done?

never even seen flax fabric at least any intended to be a laminate layer. Black Diamond Helios seem to describe flax as part of the core like this: https://www.skibaumarkt.de/en/product/bcore-d200-balsa-190-x-14-cm/ dps core looks like the same material: https://www.wildsnow.com/15521/outdoor-retail...
