Default Bamboo Propellers

In a related post I asked if anyone had heard of such a thing. So far
the only response indicates a misunderstanding of how bamboo is used
for such things.

In the tropics -- with Vietnam being a fair example -- bamboo often
has a diameter of several inches. When split AND STEAMED you're left
with a PLANK having remarkable characteristics with regard to strength
& grain.

I assumed any propeller fabricated from bamboo would use such planks,
probably glued in a steam- or water-heated clamp that would impregnate
the grain of the planks with epoxy or something having similar
characteristics. A further assumption on my part was that the airfoil
shape would be routed -- or even MOLDED -- from the section of the
planks that were fully impregnated with the epoxy, which would then
receive a finishing coat.

Perhaps we would be lucky enough to make use of a FURNITURE
MANUFACTURER or some other manufacturer who is already equipped for
dealing with bamboo.

Finally, perhaps someone can point me toward a Group that is more
familiar with Bamboo.

You can buy flooring made from bamboo from lots of flooring dealers. I
wondered about whether it was available in long enough pieces, but it
looks like it is.

Question is, whether it's stiff enough to make a good prop.

It is an interesting idea, though. The grain should be very straight &
consistent.
