Pre-treating paulownia or balsa core

I'm getting ready to build my first paulownia core skis. I've read and been told that Paulowinai soaks up a bunch of resin. I've also read that certain builders "pre-soak" their light weight cores in resin. I'm assuming to prevent excessive resin uptake during pressing. Does anyone have insight to t...

Re: Setback sidecut

I think more about what percentage of the ski is the waist placed. For freeride skis I usually use ~56% when measured from the tip. This seems to give my skis a good balance of turn initiation while maintaining float so you don't feel like you might go over the front of the ski. For a front side car...

Re: NEW SKI MAKER NEEDING BASIC HELP

See if you can find a builder in your area and ask if they might be able to help you get started.

After several months of development and testing we have finished a drag knife add-on for Fusion 360. This add-on creates support for the use of...

Hypothetical: paulownia lumber

Hypothetically if I were to buy a bunch of paulownia lumber from wholesaler.....would there be any interest in folks wanting to buy some of it? I have no idea on price at the moment. I'm still waiting to hear from the supplier. Also not really sure how this would work with shipping and such

Re: Best cut of wood for core wood

the specific cut of wood does not matter as much as the direction of the grain when you lay up your core. You can buy flat cut wood (much cheaper), rip it into strips and turn it 90 deg to place the gain as close to vertical as you can. You might look for portions of the flat cut plank that already ...

Re: woodcore thickness

The thickness of your core will determine a large portion of the flex characteristics of your ski. In general a ski core should be no less than 9.5mm thick. This is so that it can accommodate adult binding screws which are 9.5mm long. Anything less than this and you run the risk of drilling thru you...

Re: Donek Drag knife best practices

I’ve been working with a gentleman from Germany on developing a Drag Knife add-on for Fusion 360 for the past couple months. It will be released in the next few days pending approval from Autodesk. As some of you know F360 does not have native dragknife support. This add on fixed that and then some....

Love it Steve!! I may finally play with some metal this season.


For me I'd probably recess the metal in the core. Maybe a 2.5"wide strip down the center.

I'd like to cut out a mesh pattern like the Nordicas a couple years ago but I have to figure out the CNC part of that.
