some pics of resin flowing through paulownia. Have another board coming through where I press the base then profile and vacuum the top laminates on later. In this first photo you can see how resin flowed up through a 9mm portion of the core. https://farm6.staticflickr.com/5697/20763816294_d45c862105...

I second composite envisions for good buying experience. This fabric is so easy to work with, you can cut the exact outline of your board/ski. The binder keeps it together almost like a sheet of paper. I feel like you have to work resin into it from both sides and scrape the excess off both sides to...

CHris, It's too heavy at 10lbs, balsa can be lighter and is much stronger. start googling Divinycell, last a foam, these are lighter 2 to 4, 6 pounds a cubic foot, well known about in the composites industry and probably what rossignol has used for so long. Sign foam is probably not engineered for b...

https://farm8.staticflickr.com/7702/17264883745_2af64e572c.jpg I filed these out a bit of 1/8th thick 7075 alu from Macmaster-Carr. It helps to make the shape curved instead of straight lines in case they end up lining up not exactly parallel. I start by drilling 1/4 inch holes in the alu to make t...

I really like the Plum hooks but they wont be sold/exported to the USA until next year, not sure what that means for the Aus winter or for export to AUs. I bought some through a e-tailer from spain who is now sold out, except for maybe orange ones. snow.inn I have made my own clips as have some folk...

I'm pretty sure I've seen this done before long before the patent date in two places, by Marcus at Wildschnee and by Phenix snowboards both in making their 3 piece splitboards. I'm not sure how the prior art from europe affects the enforceability of a US patent. But I'd also say it's a patent as a m...

observation: I pressed a paulownia split at 50psi, 150 degrees f, 20 minutes laminating at room temp, 1 hr ramp time to 150. I laminated only the base. I noticed that next to the rings in the wood where the pores are larger, the resin had wicked all the way through to the deck up to 8mm thick parts ...

hmm, no bad smell at all from my black locust, routering or sanding. maybe you were talking about the smell of the resin you put the layers together with? I think Ipe stinks pretty bad (and the fine dust should be avoided with a mask), Paulownia has not the best smell and poplar and aspen smell deli...

I stand corrected on the black locust. I've used so much poplar that I was used to how far you can bend it without it shattering. Black Locust is a really burly and easily available sidewall material. It is harder than ash and Maple, tighter grain than hickory, lighter than ipe and not oily so it gl...

My two cents, ABS is tougher than wood, but a compressed edge into a wood sidewall is easier to repair than cracked up ABS. Mainly because you can bond in new wood so much better that new abs to abs. Also wood is easier to remove, shape in to rebuild a section of core/sidewall. I've successfully rep...
