Re: Low Density Sidewalls
I think about this a fair bit. Cap construction with a thin strip of harder wood on the edge to resist edge compression from impacts is definitely the lighter & functional way to go. However most approaches for small scale building require a lot more work in tooling. Plastic sidewalls really mak...

Re: Which fiber is best at retaining screws
I believe Trab uses a carbon fiber plate, which is numerous layers of carbon pressed with a very high density. Vinman is right, if you have a Nomex core under the bindings and have laminated the ski already, you should probably router out some channels and epoxy in some hardwood strips, then cover t...

Re: Splitboard "tounge and groove" concept
personally, I think this is a solution for which there was not a problem. If you are riding a lot on hardpack with a split (why?), overlapping pucks and maybe an extra overlapping clip in between the feet are probably more than enough to keep the halves in alignment. Look at the overlapping metal pi...

Re: UD Carbon strings on a carrier foil
I have found this product really nice to work with. The 2.9 oz weight is super thin and you can cut any width or shapes you like for targeted reinforcement https://store.acpsales.com/products/2382/carbon-fiber-uni-web-unidirectional-fiber the 4.1 oz uni from Soller composites is also a great product...

Re: Snow Surf - Ptex to full wood core
hmmm, If you are making a mold to shape a wet piece of wood with convcave areas, my thoughts are that you might also want to try laminating some fiberglass between the ptex and a flexible 1/8 veneer sheet of wood or two into that same mold. It might be easier and a better bond between your ptex and ...

Re: Hollow P-Tex
Hannes,
I had a similar issue when my vacuum hose partially collapsed since it was not able to withstand the heat in a curing oven.

FYI Innegra shrinkage in heat cure
I have started to experiment with various Innegra fabrics that I have. One thing I have learned is that while you can add a 1 or 1.5 inch strip of 2 ounce plain weave under your edges only without incident, if you are covering an entire board/ski, you have to have a symmetrical layup for higher heat...

Re: Prototype 1
Nice one Hoops! Wait, you have a CNC machine, but a trash can for a workbench, hilarious, and I love it! An easy solution for getting a stronger epoxy cure would be to get some foam paneling, screw the panels together in a box just a little bigger than your press. Blow heat in at about 300F with two...

Re: Hypothetical: paulownia lumber
Seems like there might be a retail market. Since Paulownia barn closed, what 10, 15 years ago, it's been a struggle to find a steady but small supply that is good quality. I think the market price went through the floor with factories that use it buying it by the container load from China. There is ...

Re: Pre-treating paulownia or balsa core
I've seen average viscosity resin move through 8-10mm of paulownia when cured at 140 F. End grain balsa is commonly sealed in commercial applications, I've never used it. I have also sealed cores to keep them light. Nothing technical to it. Use a squigee, spread resin across part of your core then s...

I like to use this little hand held belt sander for any situation like sanding a little flash off. You can hold this sander on edge pretty easily in one hand. I use it quite a bit and it is more compact and cheaper than a larger tool on a floor stand. https://www.homedepot.com/p/Porter-Cable-371-Ser...

hey Gav, the red board looks great! Regarding approach skis, We rode every approach ski - snowshoe variation we could think of for the decade before splits came out here in Utah in the mid 90s. If you are climbing and breaking trail in good snow they really make little sense. It is just too redundan...
