Alright, so I've got quite a few pms and such asking me to describe how I made them. So here goes.
I started with wood 2x4s (would like to try fiberglass as well) and planed them to 1/2 inch thick. Each board was cut to 2 inches wide and 130cm long. They were then submerged in water for one day to allow them to be shaped. I had previously made a jig out of 2x6s and 3/4 inch dowles in the shape I wanted the skis (the rise in the tips/tail, and the rocker). After soaking in the water, I placed them in the jig (which shaped them) and let them dry for one day. Since I used three strips of wood for each ski, I had to drill holes in them so they could be dowled. Next I put gorilla glue in the dowle holes and along each strip of wood. I put them together and clamped them in place for one day. After the glue dried, I cut the final shape of the skis (what can be seen in the pics) using a bandsaw. Then I sanded them until they were smooth. To mount the bindings I drilled four holes in the actual binding plate and then drilled these holes in the skis. I'm not sure what they are called, but in the base of the ski I inserted these x shaped metal columns which the screws go into. I put two coats of marine varnish on them, and then painted the graphics on them. After the paint was dry, I added two more coats of varnish. After everything was dry, I screwed on the bindings and was finished!
I know it is prolly confusing, but I tried my best to explain the process. If anyone would like more specific pics or description, just let me know. I will be glad to help you guys out.
