Here is a short documentation of my 3rd build. First two were with foam+wood+carbon fiber, this one uses paulownia wood only.
Setup:
3mm paulownia sheet (grain along board)
3mm paulownia sheet (grain perpendicular/across board)
~15mm inner 'skeleton' (2 stringers + frame)
3mm paulownia sheet (grain perpendicular/across board)
3mm paulownia sheet (grain along board)
Just for sealing i used some fine 110g/m2 glass on top&bottom.
Dimensions are ~115cm x 45cm, ~8cm rocker/nose. Weight ~2.6kg.
Build:
Starting with 18mm plywood board --> cut & glued together 3 sheets (54mm then) --> cut in 3mm slices.
Here are the short ones with grain across the board.
All sheets are glued using PU glue, pressed on a rocker table using vacuum:
Details of the final board before glassing & finish:
Finish: 2 component PU finish (2-component can) on top of glass/epoxy layer.
Final board:
Since I prefer riding strapless now, I attached some clear deck pads from Decathlon.
