Next boards I will be shaping are two 9'2" longboards. I posted about the design a few months ago in regards to the outline, rocker, and fin box placement. Now I'm wondering about the bottom contour and how exactly to shape it. I want them to have a rolled bottom with some nose concave, and I've never shaped a rolled bottom before. My first instinct is to make long planer passes on either side of the stringer and progress them outward towards the rail, the same on both sides of the board. More cuts to get the width to the rail first, then get further from the stringer. I hope my explanation makes sense how I see it in my head.
After this would I do the nose concave? Once the bottom is rolled. I've seen people take a template and draw a circle/egg shape for the nose concave, tape it off, make a few planer passes and clean up the concave with a sureform or sanding block right to the tape line. Just not sure if after rolling the bottom is a good order to put these steps in.
