Freshman year of high school I had a couple friends who started Skim-boarding. While you can buy skimboards for relatively cheap I decided to make my own. I designed the shape on my computer based on research I had conducted. Then I scaled the outline and made reference points on 1/2" oak plywood. Using a skill saw and angle grinder the board was cut and rounded on the edges. The boards then had to undergo a process of soaking in water followed by being placed on blocks with a weight in the center to properly curve the board. When dry the boards were covered in fiberglass then painted and finished with fiberglass resin. I made a total of 4 boards, of which 2 I kept and 2 I sold to friends. The board picture below I had a art friend paint for me.
Total Time: ~3Hrs per Skimboard
