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. -R.S.Hoover |

Never hear obout that, but bamboo laminate for a slow, low power prop... it seems possible Regards -- « Si tous les poètes voulaient se donner la main, ils toucheraient enfin des doigts d'auteur! » Philippe Vessaire Ò¿Ó¬ |

I wondered about whether it was available in long enough pieces, but it looks like it is. http://floorus.com/Bamboo6FPro.aspx 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. Charlie |

To All:
I believe we've made our point, albeit indirectly. Bamboo in the form of planks is available. We still need more information with regard to length and thickness. I will create a Bamboo Group to serve as an archive for information as it is developed. -R.S.Hoover |

The last step in creating a Group is for Yahoo to send a confirming message to your email address. After a four hour wait, nothing has appeared. Perhaps they want only Yahoo email addresses. If one of you uses Yahoo.com for email perhaps you would care to try creating a Group specific to aviation & bamboo. -R.S.Hoover |
