It would be real nice if we could all just make skis at home with a few parts and materials, but unfortunately the gear does require quite a lot of specialty equipment and gear to build. If you really wanted to you could throw some ski bindings on a few 2x4s, but you have to do so understanding that A) they probably won’t work and B) there’s a chance you’ll get kicked off the mountain.
This skier at Minnesota’s Hyland Hills Ski Area attempted exactly that, skiing a quick lap off the rope tow before resort staff came up to have a little discussion. He didn’t get kicked out or have his pass pulled, but he was told he couldn’t ski on the 2x4s.
As much as we want to say “let the kids be kids”, it’s pretty understandable as to why they won’t allow the 2x4s on the slopes. Without edges, staying in control and stopping is absolutely hindered. In fact, the ski area’s website actually states that downhill skis are required with metal edges and functioning breaks (or leashes if telemark skis), so it’s not like this is an unstated rule (snowboarders also must have metal edges, and must have non-releasing bindings).
