And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
A friend completely rebuilt a Fairchild F-24, 1936 IIRC. Many parts were fabricated from line drawings. The work in building the cowling just itself is a work of art. Absolutely incredible in it's perfection. That cowling is much more than only sheets of metal bent around the engine. The way it is formed requires a high level of skill.
No matter how much time is spent on it, with the technology of the day, it's never going to be perfectly balanced (just the nature of wood, etc.). That would imply that there would be implications for what it's attached to. [e.g. the bearings, the engine parts, etc.].
Sorry, I forgot to come back. It's to balance the moisture content in the blades. Hung vertically, the bottom blade would become heavier because wood is open cell (cellulose).
As for balance, every metal prop I have flown behind needs balancing from time to time.
However, the wood prop on my friend's F-24 is so well balanced as mea
Quick. Which picture shows a bridge over a bridge?

Horizontal is the way to store a wood prop. Anyone wanna guess why that is important?
