Ok, it’s time to make a template. If you already have a surfboard, start here. Place the super thin plywood flat on the floor, centered under the fluorescent light. Place the surfboard on the plywood with the stringer exactly lined up on the wood’s end. Use a marker and gently mark dots at the nose the tail. Then mark the center and the midpoints between. Continue until you have nearly connected the dots. Remember to be gentle or your template will move and you will have strange shaped template which will transfer to your surfboard’s shape! Next, plug in the jigsaw (and be sure you wear a safety mask) and carefully cut out the shape following your dots. There’s your first template!
