To clarify, I'm not shortening the blade. Here's the plan in pictures.

This photo shows what I'd like to do.

Naturally, I'd radius the tip better... this was just a quick
"photo-shop"

Again, the idea is to "shear" the blade tip much like a sheared wing tip.

Anyone seeing anything horribly wrong with trying this?


Removing weight from the tip will change the blades natural resonant
frequencies.

The less metal you remove, the less you are going to change them, but do
you know how much room you have between the engine firing order frequencies
and the current resonant frequencies of the prop?

I see a fair amount of risk for not much (if any) gain.
