The spacer route is the way to go. Maybe use some topsheet material which is about that thick or sand down some base material to the thickness of the difference and use a bit of contact cement if not epoxy. I usually give the center edge a nice healthy bevel too-might be enough for 0.5mm.

I've been using a bit of innegra, just patches under the binding areas on splitboards and under the heelside edge. I think it is best used for impact resistance (especially when you are just using carbon) to prevent a rock from really penetrating and getting a good grip on the edge and pulling the e...

Right Vinman, you have to account for the shorter stick being a shorter lever arm so the same stiffness piece does not bend as far into the same radius for a given weight. I reckon for every significant change in length when you get a winner board for a given weight you have a new starting or refere...

I know this is the opposite to what you are asking, but this has helped me figure out flex for different weight riders immensely. When I have a flex that I really like, I set the board in a frame wide enough no not involve the nose and tail, stand on it and measure the deflection. Then for a lighter...

I'd love to buy these board racks but the shipping would be prohibitive. I am sure there are others looking but Michigan location is probably the problem. Maybe you need to load up a big truck and do a tour through Colorado, Utah, Washington and up through BC next winter with all of this great equip...

I like your name and logo! If you were going to do a lot of veneer boards, maybe you would want to press them flat with nylon topsheet first to make a veneer/nylon topsheet then mold later onto the boards. Otherwise, why bother with a nylon top sheet for a snowboard, they don't get as many hits like...

beautiful boards, I love the strong grain in your veneer you used, the one in pics 4&5 make the board look all dished out like a burton kids board, I dig it! Do you cut those trees into slabs and let them dry for a summer before final milling? Reaally fresh and nice looking lumber there. I went up t...

Cool! If this year's boards made from Paulownia get dented up on the base, I think I'll laminate some 2mm hickory or maple on the bottom of the core like these earlier skis had.

they have some for sale at woodenskis.com

http://www.eastwood.com/eastwood-s-2k-aerospray-high-gloss-clear.html This works fairly well for snowboards, $22 per can which can do two boards and is a one day use before it sets up in the can. I doubt anything works for skis like a nylon top sheet does. Like all auto paint clear coats the VOCs ar...

hmmm, did some more reading. I'm thinking the innegra will help protect the base layer composite from impacts, but probably not much help in board breakage which appears to usually be compression failure on the top side. Could be best to just stack diamond shaped patches of unidirectional fiberglass...

I'm guessing it beats fiberglass for beefing up a carbon laminate because it wets out better or doesn't absorb water, it dissipates impact better adding toughness to protect a carbon layer, because its lighter than fb, it has a higher ultimate breaking point. The thing that makes me skeptical is whe...

As I've started to make boards that bend more, I have been backing up thin carbon laminates with innegra as the outer layer in the high load areas instead of S2 glass for the weight savings. It is pretty hyped so far as adding toughness to carbon composites. Won't know anything until this year is we...
