I just started a new board with strips of western red cedar. I am used to making boards out of foam but this is my first one made out of wood. I was wondering if any of you guys know how much more rocker is needed on the rocker table vs the rocker you want on the board. I,m guessing that the woods elasticity will make the board with less rocker then the table.

is it twice as much? I also understand that the thinner the board is the less ''comeback'' the board will have. thanks for any input.

Depends on how much fibers are you going to put and concave also.
It will be -40% to -20% total but increasing towards the tips.
Concave increases slightly when rocker decreases.
