The Tuttle installation sure seems strong. Adding foam to the Tuttle seems to make this connection solid- so much surface area now to adhere to. Just use lots of filler, resin itself isn't that strong and you'll cook the foam with too much resin. Board lady has great instructions. I added some carbon to the bottom bridging the Tuttle and the board. I've seen some very lightly built boards handle everyday riding. I suspect most of what ends up being built is way over engineered. Have fun with it and good luck!!
Thanks! I'll keep you posted on how it comes out. Another issue I've just encountered is my Kiteboard that I planned to install the Tuttle box in isn't quite thick enough to fit the entire tuttle box. it would have to stick out the bottom of the board by about 1/2 an inch or so ...
Kind of defeats the purpose of the tuttle so I think I'm going to just install the tuttle in a regular surfboard of mine. my question is , aside from reinforcing the deck with some glass, do I need to reinforce any other areas of the board? Such as the bottom of the board towards the nose so that it can handle some nosedive wipe outs?
