My program Virtual Shaper was specially designed for me. There are 3 modes: Shape, construction and CNC. With the shape module I design the outside shape.With the construction I can define the PVC thickneses (to take off for the EPS blank), the taper of the PVC thickness, any reinforcement blocks and the size of the inserts. Which is then all cut by CNC. In the CNC mode I design the blank, place the shape inside and define the milling paths for the different tools and the positions of the vacuum suckers.
I can define the flow of the V and concave with 8 values:
That is indeed quite impressive. I think that "parametric" CAD is the best way to do surfboard shaping, but is not explored much. You also do the concaves the same way? From would I read in your post, I thought their profile can be asymmetrical?
BTW, I am a big fan to run the concave through the full board. To me it does not make sense to have a flat V in the back. the board is much more predictable. But with the standard shape program almost everybody uses, it is near impossible to design the proper rail-side curve to allow this.
ever wondered why racing sails are mono film. Simply because nothing beets mono film. Fibers only work in a matrix i.e. with rasin. Therefore this carbon layers don't bring anything. Only a better margin for the supplier.
