Re: Pre-treating paulownia or balsa core

We have done some test on the subject using vertically laminated balsa, the sealed laminate was actualy heavier than the not sealed one and a little bit more prone to delamination.

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

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'...

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.
