Why not just in one go?Will need to thinker how to do just a topsheet coz I normally don't do everything in one go.
to extract some resin from the resin rich area around the resin feed line once the board is infused.Also, if you don't mind, why 2 inlets on the right hand side?
There are different ways to do it. The advantage for me is that I take a board with a finished surface out of the mold (I like the raw look with the fabric print trough, not for everyone though). But all the other guys I know build their boards with a flow media on top, but they don’t really have less trouble than I have…do you recommend flow media for an infusion?
Yes this will be an issue, but making a ski or snowboard with vacuum infusion is certainly possible. But if you have a press at hand it will deliver better results! Let me put it that way – I manufacture a lot of parts with vacuum infusion at work, but I built my skis wetting out by hand and pressing in vacuum.i thought the issue would be getting epoxy between the core and the base (for skis) and the edge and vds rubber would be an issue to fix.
The only advantage I can think of compared to a press is the cleaner process where you don’t have to mess around with tools full of epoxy…
Biax E-glass and UD flax lengthwise. So it’s a triax layup. The board is with 1.9kg pretty light (I broke this particular board when I had some pretty bad impacts after high kiteloops, but I broke my knee as well… And the new version has an optimized layup, weights the same and is stronger. I’m working now on a version which is even stronger and MUCH lighter).yes, it's a fg but what kind of like E glass, S glass, biax, triax, quad...? Smile
Inserts embedded in epoxy/cotton mix. I cast them in the unprofiled core to make sure the hardpoints are perfectly flush. Basically the same story as for the rails – works a charm!What we can't see on this photos is how the bindings inserts are made
Thanks!... but that is an awesome looking board!
If any more questions, feel free to ask!
Cheers, Reto
Thanks Reto
Cool thing this inlet, cheers. What does flax do? How heavy? I suppose it's light...Looks like you're CNCing your core?
The 5mm foam sheet 2400x1200 is about AU$150. Less for a bamboo. Way to expensive when you add all consumables et.al for building a board.
I use a bamboo as core and Paulownia as top layer. The top layer keeps the rocker and concave in. Glass is minimised, so is epoxy.
The board is indestructible, clocked +200 hrs than sold it.
If I could find a bamboo supplier or China direct, that would be a game changer. but than, I wouldn't be doing it in a laundry:)
This is the topsheet with a PU premade rails:

Natural fiber which can be used as reinforcement for compositesWhat does flax do? How heavy? I suppose it's light...
Nope, done by hand with several jigs and a routerLooks like you're CNCing your core?
why the heck bamboo? it weights a ton...I use a bamboo as core
Somehow i manage to break a lot of things which I think off they're indestructibleThe board is indestructible

Ok,
so back to the topic.
One suggestion from a local shaper is to wait for epoxy to tack a little, maybe even applying a bit of epoxy on tacked surface and than doing a hand layup with no vac or anything.
Would anyone agree with this? Is a tacked epoxy a way to go? Do we need to wet out both, a topsheet and core?
