Congratulations, you've succeeded in giving everybody who reads this just enough knowlege to be dangerous. If you're considering building a wood propellor for ANYTHING that spins real fast, PLEASE PLEASE PLEASE make sure your woodworking skills are up to snuff. And use a waterproof glue such as Titebond III, resorcinol, or epoxy. Explosive delamination is a very real possibility.

What ever happened to Individual Freedom, Liberty and the responsibility that goes along with it?
The man gave an excellent instructable that was accessible to those without the luxury of a tertiary education.
Normal Wood glue is fine- see how hi-tech bi-plane fighters props were- they were used hide and hoof glue they did the job fine.
As long as the constructor follows the glue instructions (dry and free from grease/dust etc & is clamped (expulsion of air) no probs.
As far as I recall, airboat props are encased in a wire cage. If it were to delaminate- the centripetal force and airfoil vortex would blow it backwards- so nothing to worry about in front.
