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?

thanks

Sure MM, Like this Dupraz board: http://www.dupraz-snow.com/dupraz-d1-6-3.html or this Gentemstick: http://www.gentemstick.com/productsDetail/id_129/ maybe they are done by isosport as the is one identifies: http://furbergsnowboards.com/snowboards-and-splitboards/the-freeride-split/ I guess I am won...

tinted topsheets

Anyone know who manufactures the tinted topsheets that are pretty popular these days?

thanks

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...

I would try a stronger vacuum pump. I have had waves under a veneer layer before from a vacuum hose line that partially melted shut and also probably from not scraping the resin off the laminate fiber thoroughly enough in lay-up.

Hey Gilo, unrelated, but I would put your uni carbon under the glass on the deckside. Uni carbon is pretty thin and is less prone to failure in compression if it has some glass over it or a veneer layer over it. For color, You have opaque pigment for your resin or some kind of very thin fabric. If y...

I second MM, before becoming a bc boarder all I did was ski bumps. Metal was always discouraged because it would get bent. No carbon just E-glass to be able to deform deep and handle it. Toughness and front end energy absorption is the goal, you could add Innegra throughout or S-Glass in the tail if...

I was having a hard time trying to find the time to laminate a board for personal use. Finally got a short window of time from work and being a Dad. Wet out the base and edges real well, wet out the core, placed them together all perfectly aligned in a long vacuum bag ready to go. Then I realized I ...

I think it is too far even for what I've been trying to do. I've been trying to think around ways to improve the compressive strength of real thin carbon layers on the deck side of splits. Another challenge with adding the nano-powders to improve resin and overall laminate toughness is that it alrea...

Ha, That's kinda what I have been learning. Thanks for the quick response. Reckon I'll just use the maple I have and adjust flex and weight elsewhere in the recipe.

It looks like the bow makers gobble up any clear yew at pretty good prices if you find some good logs.

DTrain,
Hey I saw your skis with the yew sidewalls on facebook. I'm trying to increase the compressive strength of some paulownia cores without stiffening them up too much. Does the yew wood seem more flexible than say hard maple?

Do you have a referral for finding some pacific yew?
