I planned out and designed the outline for my board. Then I shaved the blank down to my desired outline, it isn’t exactly as I drew it, but I like how it turned out. Then I shaved it down to my desired thickness. These two steps take the most physical work and time out all the steps in the shaping process.
Luke, what is it that you are hoping this outline will translate to when the board is in the water? Are there ways to test this? How is the performance of the board impacted by the thickness? What are the advantages and limitation of a think board? Of a thin one? What is the sweet spot that you are hoping for?
