Base material for sidewall

Post by sleepycp »

Has anyone used leftover pieces of base material for sidewalls? I have all these long pieces of treated p-tex laying around, and it seems like that could work. ??

Hey sleepyycp. I used that method with my latest pair. we cut out the sidecut of the core, and then made sure it was smooth and vertical, then we resin'd 4 strips on each side of the ski. It was easy and worked great. Durability is pretty good too! you wont be pulling them off in a hurry...

The only problem we found, was because we used 4 strips each side, we used all of 2m of base material... and if we used less that 4 strips you have to have some pretty good ways to keep the core aligned during pressing... (even with 4 layers on each sidewall, for a small 10cm section we routed it away... so you have to be carefull. i would use more layers next time but then you are using so much time and base it becomes inpractical.

So bottom line i figure is, using ptex base as a sidewall is great. but only really good if you can aline your core to +-0.5mm core shift.

For our next ski we are just going to use plain old maple sidewalls, this way we get a really neat finish. Then we will use a marine varnish to seal them so they dont get all soggy inside from moisture. PTEX is def more professional tho.

Hope that helps.

Yeah, that looks pretty good. There's so much wasted material when you cut out the base, it seems a shame to waste it. I think I may try it. Plus, no pesky flame treating!

Well, you don't have to flame treat the base material because it's already prepared for bonding on one side, and as for flame treating regular sidewall materials, G-man's posts scare me.

The problem is just that. The base material is just prepared at one side. You need to flame the top and bottom.

and.. despite what G claims, flametreating is not that scary.
