Here's how to graft two windsurfer fins together to make the lifting part of a hydrofoil.
I lost the front hydrofoil blade from one of my Aquaskippers
. This new blade works great as a replacement.
The foil section is just right for the purpose. And it's a really quick project.
The resulting blade is strong enough to use for an "air chair" or "sky ski" type hydrofoil, or any other weird hydrofoil project.
You can get windsurfer fins cheap at flea markets and yard sales.
You'll need the following:
Two windsurfer fins. Mine were each 9" long.
Epoxy. Not "5 minute epoxy". That stuff is crap.
Power Sander. I used a belt sander mostly.
Dust mask, safety glasses, clothing to keep the figerglass off your skin.
