That's right! People are discussing technical sailing issues and learning!
Metallurgy, sails, forces, rocket planes - it's all here folks.

Betcha didn't know about torsionally pre loaded propeller shafts - they
triple the life of your transmission by absorbing the shock of shifting into
gear. They also reduce cavitation! Can't use them on rocket planes because
they have no transmissions. But if they did, they'd be swell!

Another handy tip - use leather gaskets on your liquid oxygen systems!

Next lesson - predict the tides with an octant!

No, I didn't know that.... BTW how do you "torsionally pre load" a shaft, keep a
brake on it until 100% load is reached? Doesn't sound too practical. And I think
that if anything, a torsionally pre loaded shaft would exaggerate cavitation &
shock loading on the tranny.

Sounds like a good way to have a very dramatic fire.

What happens when the octopus' big brother comes along to get it back?

You're a hoot Gilly, please stick around.

Make the shaft out of a spring!

Explosion, not fire!

I'm just warming up.

That would not "torsionally pre load" the shaft, but it would provide a torsion
buffer or shock absorber if you prefer the term.

That's what I said.

An explosion is simply a very dramatic fire.

BTW many kinds of hair conditioner, mousse, etc etc, will react 'dramatically'
in the presence of medical oxygen. Beware when taking a loved one with a fancy
hair-do to the emergency room!

Doug,

My sincerest thanks, I can never repay you fully for this timely, life
saving advice . As you may know, I insist that Mrs Gilligan wear a 2 foot
tall beehive hairdo at all times. My heart would break at the sight of that
towering inferno. Should a medical emergency arise, I shall refrain from
taking the Missus to the emergency room.
