:: View topic - Tip/Tail Polystyrol-plate?

Hello everybody,

Yes you can glue with epoxy, but it can be too soft, so it will not withstand compression. Look for Airex or Depron, in a shop selling RC model planes.

i'm looking into making a pair of twins for all mtn. / park skiing and i was wondering if any of you super duper smart people could fill me in on how burton,atomic,elan and dynastar can put edges inside the base of the ski.

What do you mean by inside the base of the ski? Do you mean that the ski has an edge on either side, then one in the center of the base? As far as attaching the edges to the base of the ski, check out the rest of this site. I am not really sure what you would get out of having edges in the center of the base.

supposedly the extra edge helps prevent damage from grinding on rails, concrete, etc. i would try routing out a slot where you want the edge to go and tack the edge in place.

Have a look at this skis:

its probably just a slot cut in the base with another edge tacked on. but personally i think that extra edge business is crap, its not gong to stop the main edges from cracking and falling out,

also i beleive what dynastar did was put a metal plate above the edge between the core and the edge(not an extra edge sticking out of the base), hope it works cause i love tm's but the edges are crap on rails.

The dynastars are really great. I bought this year the skicross pro and they ski really great.

Ice and hard snow are no problem at all.

^you were right dynastar did'nt put an extra edge but the reinforced it like mad. but atomic did. go here http://winter.atomicski.com/technology.php and its like the 2nd one down

Greetings,

Been lurking and am very impressed with all the skis I've seen on this forum (and on skibuilders.com).

I've been sufficiently motivated to consider making my own skis. However, I'm going to warm up by taking a pair of old skis that were destined for the garbage heap and see if I can make powder boards out of them.

Here's my idea. I have 200 Pre M3's which is a soft flexing wood core ski from the early '90's. I plan on takings 2.5 cm off the tip and 12.5 off the tail. Then I'm going to rip the ski in half and space the two halves with dowling. The top will be capped with a yellow birch lathe and I'll build a binding platform onto the topsheet. The center will be filled with foam, sureformed down and the base built up with P-tex. I may cut out a swallow tail for aesthetic appeal and to reduce the weight. The finished dimensions I'm looking at are 155-135-142. I've done boat construction so feel fairly confident with epoxy and wood working skills. The consequences are minimal IMO and it should be a good learning experience. And who knows, maybe the skis will actually work. I plan on skiing them Tele, powder only and in the trees.

Your thoughts please. Am I wasting my time? What about the dimensions? I'm a big guy at #250 and need all the floatation I can get.

I suppose you have seen this: http://www.skibuilders.com/phpBB2/viewtopic.php?t=174

Thank you Davide, yeah, I did read that thread. I even corrosponded with the Pyride guy a little.

I guess what I'm most curious about is the dimensions of my planned skis and if they're realistic.

Those dimensions should make for a pretty good powder ski. I am pretty convinced that 150 to 160 mm wide is about as wide as you ever want in a ski. Much wider and you have to really keep your legs spread just to keep the skis from running over each other. You will probably have to put leashes on them if you mount downhill bindings, and they are going to be pretty heavy, but with all the float, weight shouldn't be too much of an issue.
