Turn Initiation and release
I am curious as to what kind of changes to the outline of a ski changes turn initiation and release. Is it the blend curves at the tip and tail or the position of the waist or tip and tail bends that you find increases or decreases these factors? Some people refer to turn initiation as "hook up...

Location of the boot center using the exact center of the ski
I have been reading a fair amount of reviews of skis and they always refer to the binding mounting position as -8 or whatever from the exact center of the ski. I can understand this if you have a twin tip ski but if you have a directional ski with a longer tip than the tail how does that relate as t...

Re: AutoCAD learning curve
I don't know of any specific tutorials but I have seen some explanations on the ski builders website if you search around. Mainly, the secret to CAD is just getting in there and familarizing yourself with the commands and then learning how to build geometry. I was very lucky since I started out on a...

Re: Thickness profiles
Thanks for the feedback. The variance of shape at the center of the ski has mostly to do with minimum flatness in relationship to screw depth and binding mounting areas. ISO 8364 is the specification that you are referring to. Section 4 states that there is a maximum thickness and flatness at a cert...

Thickness profiles
I want to experiment putting the thickest point of the ski profile forward of the normal position that most people do. I was thinking 50+ mm. I have seen thickestest points at the waist, Mid running surface and would like to try going forward of there. Has anyone had any experience at thus and what ...

Re: Blending Effective Edge with Tip Width Radius
My suggestion is to put a blend curve in that is tangent to your sidecut and the center of it in on the line you call your wide point or effective edge. The other curve I am guessing from you comment is the forward contact point where the board starts to bend up. Make sure that your blend curve inte...

Re: Designing Multi -Radius Sidecut AutoCAD/Fusion 360
If I was to draw a multi tangent side cut shape, I start out putting my first radius at the waist. You can check to see if the radius is on the waist by drawing a vertical line using the center of the radius you just drew. Next I offset that vertical line by the length that I want the center radius ...

Effects of an inbalanced layup on camber and tip/tail heights
I am trying to figure out which way a molded ski will normally move with a layup that has two layers of glass on the bottom the same thickness and only one layer on the top. Do you think I will get less tip height or more tip height? I am curious as to how much I need to compensate for the changes. ...

Re: Full Cap Issues
One of the big problems with vacuum bagging is getting enough pressure. Especially on steep sidewalls. 45degree is about max before you starTto have issues on caps when vacuum bagging.

Re: Snappy or Poppy Skis
Thanks for the feedback. As much as I would like to think there is a scientific answer, everyone still reverts to the tried and true method of ‘try this and try that engineering’. Of course, there is scientific logic here but nothing beats a pile of prototypes. I see it all Winter with K2 showing up...

Snappy or Poppy Skis
I know that a lot of skis are built these days with two layers of titanal which tends to make them smooth and damp. ( and they tune well) However, I have skied on some metal layered skis that have no snap to them while others seem to be quite poppy. It does not appear to be extra camber that is maki...
