Hi
I'm trying to create a 3 foot 6 blade prop for pence, or cents? (my 3rd world idea)
Any ideas how to 'nest', tesselate 3 props together would be appreciated.
Please see my web page for full description.

This could be of considerable use to 3rd world countries.

I think you would need to make some sort of hub. A timber disk about 200mm in diameter, with each blade bolted to the hub with three 1/4 bolts.

Nesting the PVC pipe could be done but you would end up with a weak hub, remembering the blade roots cop the most strain.
