They are molded during layup, screws are "a bit structural" but they don't do much, I sand and etch the stailess steel and it bond insanely well.
What do you use to etch the metal?
1 part of cloridric acid (30%) and 2 part of hydrogen peroxide (130 vol.) at 45°C for 10 minutes

Those skis look really great. I am working in a similar ski with B-COMP-core as well. Whats your coreprofile?
Profile of the core is 2.5-11.7-2.5

Re: Fugeskis 2019

Nice work, those look excellent! I also like the tip protectors :) I'm curious about how they're applied. Are they molded in with the ski during layup (and then, are the screws just ornamental), or are they applied afterwards and held in by the screws? If it's the later, do you have a template you'...

How’s the flex? I like the tip proctectors. Did you machine the entire piece?
The Skis are actually too stiff in the tip area, I will thin them down a bit.
Protectors and all my temeplates are laser cutted by an external company, I send them the CADs and in one week I recive the pieces... Magic!

Re: Fugeskis 2019

very impressive, both tool chain and results! could you elaborate a little on your core profiling process, as shown in the second video? That machine looks really nice... For profiling I use an horizontally mountend bandsaw with a 14 teeth per inch blade, the feed sistem works with a small motor. I...

I have drilled new holes and I put in metal inserts with epoxy. I still using it.

White background for sublimated grafics

I would like to using sublimation for my grafics but before start building all the stuff needed I want to find the best way to create a white background. In my firsts attempts I laminate the topsheet with 2 layers of 40g/m^2 of FG using a resin mixed with a white pigment at 5% (max allowed), on top ...

In theory, yes, if it is insulated well enough. It all depends on the environment of the blanket. For example if the blanket is in direct contact with an aluminum cattrack (=big heat sink) it might not reach the desired temp or take much longer than with a wooden cattrack which conducts less heat. ...
