I used the Marker Schizo also but I find the position pretty sensitive. It depends a lot on how the waist is positioned in relationship to the mid running surface when you design the ski. I have skied on skis in the past that appear to have the mounting position in the wrong place. I keep moving the...

Beaver Machineworks in Woodinville, WA has built molds for years. They have a 5'x10' CNC router. I have had aluminum molds, form blocks, and routing templates made there. I actually used to work there back in the hay days when we built wakeboard,waterski and snowboard molds for a lot of companies be...

So are you talking about the tip (widest point) or the forward contact point? Historically the waist was around 55% of the running surface length. It seems like the free riders who ski switch are mounting their ski forward of this point so they can ski backwards so the 42-44% appears to be more appr...

2. Why are the tips and tails of most skis so thick? Durability, stiffness and vibration damping. If you have a very thin tip/tail it won't be stiff. Flexural stiffness in a sandwich composite comes from separation of the top and bottom fibers. Flexural stiffness is important at the tip when plowin...

I have working on some new shapes and some of the people that I have chatted with always mention everything in relation to the exact center of the ski (total length divided by 2). They want the mid running length on the center of the ski. With tips being much longer than tails these days, I find it ...

The skis came out with rocker. The formblocks had 5mm of camber designed into the shape.

UHMW is really hard to get good bonding unless it is properly prepared using a flame treating process but you can't let it sit around very long since it starts to oxidize again and then it will delam. I have seen a number of guys using the rubber foil on the bottom and top of the sidewall to help wi...

Can't seem to get the Blizzard video to work.

We made a formblock with 12mm camber to see what happened and ended up with about 5mm camber after pressing another pair. I also noticed that the running surface shortened up also. We designed the ski to have 1310mm
running surface length and now it is around 1250mm. Scratching my head here.

You mentioned 175 degree heating but is this top and bottom? That was the plan but I am guessing that the lower formblock is not a hot as the top. I forgot the theory of changing the temperatures betwen the top and bottom and what lowers or raises the camber. If I recall a higher temperature on the...

I know this has been an issue before with other larger makers when metal is added. I would only do one layer with an asym layup and .6mm sounds mighty thick but I dont really know. If you do only one layer of metal, you end up with a bi-metal spring effect. When the ski gets on the snow, the temper...

We recently pressed some skis with .6mm Titanal aluminum on top and bottom. We were using wood formblocks with bolster tubes and airbags. The skis came out with no camber. We did have some delamination issues but I am confident that the Titanal had been sitting around for awhile and had oxidized. Bo...

I am curious whether anyone has done some experimenting on positioning the contact point at different areas around where the blend curve and the side cut meet up at either end of the ski. I am interested in finding out if this effects the way the ski hooks up or is it more about the thickness profil...

I have a question about true center on a ski. I am assuming the on a ski the has the same length tip and tail, I would think that the true center of the ski would be the same place as the MRS. (Half the length of the ski) However, skis are being designed with longer tips than tails. To design the po...

I mostly agree with both of you on the "gut feel" and the numbers. Right now we are working on an issue of trying to figure out if a wood sidewall is as strong as an ABS sidewall. I know there are a lot of different issues with wood versus ABS but this is a case where you do an impact test...
