Hope you all had a good season, just cleaned the shop and getting ready to build some boards for this year and I'm curious about using some different materials. Planning on making a few of the All Mountain boards with the standard core setup (poplar/aspen with oak sidewalls) but looking to add something new. We usually use a 1" strip of carbon tip to tail that works well but interested in using some of the hybrid fabrics this season. Would like to hear your thoughts on them?

Thanks all. Keep up the building! www.chair2snowboards.com

My next ski build will be using a custom hybrid fabric comprised of 12 oz. biaxial carbon (+/- 45 degrees) + 10 oz. warp unidirectional E-glass = 22 oz/sq yd total fabric weight.

As always I will be using hardwood sidewalls, Ipe this time. This Amazon rainforest hardwood is very hydrophobic, it does not absorb water. It’s at the top of the Janka wood hardness scale.

What are you going for SHIF? Weight will be the same, no? Stiffer for that weight I suppose so a thinner core? I have had a similar thought of using carbon biax and longitudinal fibreglass so you get good torsional stiffness but still the flex/dampness of fibreglass rather than carbon in the longitudinal plane.

Chair2:
Snowboard materials had precured sheets of glass with carbon stringers that people have used on here before with good effect. Not sure if they still do.

You describe it perfectly Falls. I’ve found some high quality biaxial carbon fabric and I’m aiming for maximum torsional stiffness for my new ski design. The biaxial fabric contributes to the longitudinal flex index of the ski so I may use lighter weight uni glass, I have both 6 and 10 oz available.
These all mountain carvers are my narrowest skis yet, with the deepest sidecut:
Length = 186cm
Widths = 135-98-122mm
30% elliptical rocker
70% camber, 4mm
Effective edge = 152cm
Radius = 20 meters

I used Ipe on a couple of skis last season. The wood is incredibly hard. It's also stringy. I don't know if that contributes to anything but I really like it. Looks great as a sidewall. It has a deep red or brown color. I went through a lot of jig saw blades, maybe a dozen. Buy a high quality blade.

Shif, I like your style. I'm building a similar ski but wider. 12 oz biax with 9 oz uni carbon, 110 underfoot on 183, no wood sidewalls for me though.

I'll be using a different core design to cut weight though. Shooting for under 4lbs per ski, the proverbial lightweight beefy BC ski...

I could probably go a little skinnier and shorter maybe a 178 with 107 underfoot.... Probably buys me 1/4 per ski.....
