This will not be a comprehensive treatment of all the different ways to accomplish these tasks, but rather just the ways that I have personally done it which work well for me. For alternatives see SkiBuilders.com, where they have collected detailed how-to’s on how they and others build siks and snowboards, and host a great forum with even more information on alternatives.
What about skis?
I've built one pair of skis, and they turned out great. You’ll find that ski and snowboard construction are amazingly similar. You can use all of the information here to build either, even though it all refers to snowboards. It’s okay :)
There are a few placeholders which I will try to get to Real Soon Now, but otherwise the articles that are here now are technically correct and up-to-date. The only exception would be articles in Category:Not Ready. Take them with a grain of salt.
