How to build a Twin Tip Kiteboard - Part 1 Preparing the Core

This is the first video in a 5 part series where we show you how we built a wood cored twin tip kiteboard with cast urethane rails.
In this video we get the wood core ready for laminating by cutting the groove for the urethane rail and fin pockets, next we cast the urethane into the board. After the urethane sets we'll take it back over to the CNC machine and we'll mill flat the bottom, mill in the pockets and holes for the binding and handle inserts, and then flip it over and mill the deck profile.
In the next video we'll build the rocker table, which is the form that will give the board its curve along the length of the bottom.

I would like to know his name or another product I can buy here in Brazil

Yeah very informative and good video 👍

I would love to see this done by hand.

Good project - would it have helped to degas the urethane in a vacuum chamber before pouring to get rid of the bubbles? TY

[@FiberglassSupply]

Thanks, you know that is an interesting question and I am not sure. The pour itself was bubble free, the bubbles showed up as the urethane cured. We do have a degassing chamber, I may give it a try on a test piece. Thanks for asking.

[@kisoia]

@@FiberglassSupply Sure, thanks for putting out these videos. It is interesting the bubbles showed up during curing and not during (or previous) to the pouring. I have used Smooth On products and found them to be very good. Maybe their tech folks could help out with some advice? TY

Hello I live in Brazil and I would like to know what are these products that you use to make the edges of the board, what material are these red ones?

[@FiberglassSupply]

We used a pourable urethane resin to do the rails, however on boards we did after this we used epoxy resin filled with 3M bubbles.
