You're not supposed to mix imperial and metric units of measurements up.
Certainly not when baking or preserving. Or doing any kind of engineering calculations. Unit consistency and all that LOL... I still have my conversion tables somewhere. I find that once I get below half an inch, I prefer to work in mm.
Have you thought of cutting a mountain bike inner tube(on the inside) and using that?
I'd need a fair few inner tubes to glue and layer. Which I don't have. The rubber flap stops stuff being blown out the back of the deck at a fair rate of knots., and I don't think inner tubes would have enough heft to stay intact.
