Re: super light freetourer

I'd also be interested what UD you used in +- 17.5°. Surely carbon, but what weight? If you want it damper (though a bit heavier), there is some nice carbon/flax mix UD from bcomp: https://www.bcomp.ch/products/amplitex/.
I really like the feel of carbon and flax mix.

Re: super light freetourer

Wow, really nice! How long is your Ski? And what happened to your edges? :) Will you cut your climbing skins in the exact shape or leave them straight in the "uneven" part of the edges underfoot? I currently am on a similar project, though my ski will be a bit smaller. I also use Bcomp Cor...

Pre-treating TPU ski end?

Hello, when searching for TPU almost all results are for topsheets. Now, I bought some ski ends made from TPU: https://www.skibaumarkt.de/produkt/skiende-245-mm/ Skibaumarkt recommends Sanding them before laminating. I wonder if some treatment like flaming (used for ABS sidewalls) helps bonding when...

Re: Pre-treating paulownia or balsa core

I will be in for some Balsa lightweight touring skis within the next 3 weeks. I shared exactly the same idea. After poeple here did pre-seal, I will go for it, too and publish my findings. I have a very thin epoxy though, and the idea with the wood glue seems sensible, too. Did someone ever try seal...

Re: Methods to keep core/ base still during press.

Glad it worked. Have done it like this on the last 6 pairs of skis, never had an issue and found it always easy to handle.

Re: In the press today - as Swiss as it gets :)

Hi, I cant recall the exact numbers, but the last one I built is pretty much this way: 130-88-118 2.5mm - 14mm - 2.5mm; mix of Poplar and Ash 0.? Wood veneer 300g/m² Uni Flax 300g/m² Triax Carbon Wood Core 300g/m² triax Carbon Definitely more than stiff enough with this setup, but I like em rather s...

Re: In the press today - as Swiss as it gets :)

Hi,

yes, 300g/m² on top is superior to the 120g/m² on top and bottom. also way easier to work with. The 120g/m² is a PITA to lay up, the thicker one is much better to handle.

Re: In the press today - as Swiss as it gets :)

Hi, just saw your questions. I re-built that ski since. 1) I didnt use any glass 2) I only used 300g/m² uni flax on top (right below the wooden veneer) as bcomp states 3) 300g/m² triax carbon as before Result: Perfect! The single layer of flax on top is great, better dampening the very springy carbo...

Re: Festool vacuumpump

Hi, you could give it a try, the maximum vacuum is enough. What might be more of a problem is the little flow the pump has: only 2.7m³ per Hour. That means that your vacuum press really needs to be airtight, a little leakage anywhere would be a problem probably as the pump isnt able to "pull&qu...

Re: Methods to keep core/ base still during press.

Sounds sensible. Different positions on left/right side will only be important in skis, not in boards.

Re: Methods to keep core/ base still during press.

HI fred, I have been using this method for the last 5 pairs of Skis I built and it works fine. I am on a vacuum press however, but that shouldnt change much. I screwed the spare base parts to my wooden mould, never have any base movement this way. What to think about: as the tape is on the bottom of...
