I'd like to add that from a mechanical point of view it is best to have the 45° layer facing the core. The biax layers have a lower apparent stiffness in the main direction of the core, which will result in less shear stress at the bonding interface between core and laminate and help with longevity....

Care to share the layup and core material with us? Might also just be insufficient strength wise. In my experience from work it is usually not the epoxy, even though that certainly doesn't help (still might be the cause...) Also the finish on the fabric will go bad over time, which might have just a...

A lot of it comes down to what tools you have available to you as well. You really don't need a lot to get started, but the process will look different if you go at it with a router and jigsaw or with a CNC router and pneumatic press. If you have specific questions we're happy to help tho. This is h...

And @pmg: I would advise not using the planar on end grain balsa. If you have a fancy helicoidal cutter you might get away with it, but i wouldn't recommend. Thickness sander would be best, otherwise router sled with template or CNC machining. Hi, I used the planer carefully (max 0.5mm ar a time, w...

I can't believe they are holding up with a layup this light! Looking good tho!

Man i hope your laser safety goggles are up to snuff. These lasers without enclosure scare the living bejeezus out of me...

Thanks for the write up! I built kiteboards in infusion
and helped building entire race car bodies this way but never attempted a ski or snowboard. Was always afraid the edge bonding not being great. Do you have some long term experience with this?

Alright got to ride them again on a short after work night ride in amazing conditions and they just worked really well. Sorry I have a hard time describing all of this as I never really read any ski reviews and I am lacking the lingo

I'm used to it and was actually expecting it to be harder than it was in the end. I am rather used working with those materials from other projects tho.

Compared to a single layer of triax fiber glass it is a lot more faffing

Alright I tested the ski today in varied conditions. Aaaand the verdict: meh. or meh-ish... There was a lot going on and I have to ski them a lot more before I can give a better feedback. If skied aggressively and fast they performed well. super snappy, agile. But when half-assing things they can be...

Yeah this is the one point I'm really not sure about. Let you know!

Topsheet is visible carbon The dimensions are 1850x90 underfoot. And wanted to give Magne traction a go on skis for a long time. it worked well on my snowboard so went for it with this built. The skins are cut to the same wavy shape. Carbon or Glass UD with biax flax is my go-to layup i have a lot o...

Hello Everyone! Wanted to show off my latest build project. I like to try things which resulted in this weird contraption. The goal was to make a freetourer with an arbitrary weight limit of 1kg per ski. It all started with me questioning the traditional triax layup. The hand-wavy explanation to my ...

Love the shape of those! Hit me up if you have specific questions on the infusion process.

Cheers!

Yes I've done that a couple times. For my first pair of skis and then again last season when i was building 3 snowboards that were all different and i didn't feel like building more moulds. I made a tip and a tail rocker profile with a 5mm mdf inbetween, and then another 3mm mdf across everything. E...
