White lead & castor oil on prop shaft?

Many years ago I used white lead in the restoration of the roof of a
wooden railway car. We used the traditional method of stretching
canvas over the wooden roof, soaking it with a paste of white lead and
linseed oil,and nailing it before it shrank.With occasional painting,
it lasted outdoors for over 20 years.

Wow. I especially like the part where "about fifty men"
install the wing.

Looks like they used the mixture as an anti-seize compound...

If white lead will harden castor oil then I would suppose the
opposite--that it was used as a thread-locking compound.

But if it does not harden, then I agree, anti-seize.

....

Looked like there was a separate locking gizmo to ensure the prop stayed put...

Now that you mention it, I recall that too. Besides, one of the old
farts
here confirmed that white lead was a traditional anti-seize compound.

I guess that it must not castor oil the way ti does linseed oil.
'Boiled'
linseed oil is linseed oil that has hardening agents (driers) added to
it. When white lead was used, it was heated after mixing, hence
the term 'boiled'.


Only ten men to put the prop on ;-)

Were it a Corsair, they would have needed a boy too!

Sorry to disagree, but When linseed oil was first used in paints,(as was
white lead) the drying--(actually oxidation-not solvent evaporation) was
accelerated if the oil was first "cooked,or boiled"--Later chemists
added Catalytic-type compounds which did the job much more effectively..
You had to caution the livestock trade to use only Raw Linseed(as a
laxative) and not the boiled or it'd kill the animals.

Sorry to disagree,

I think if you re-read, you'll find you are not disagreeing.

white lead) the drying--(actually oxidation-not solvent evaporation) was
accelerated if the oil was first "cooked,or boiled"--Later chemists

BTW, it is still called boiled, even if it wasn't heated.

I've found that when restoring or reproducing vintage things,
attempting to find the correct materials is a real challenge, if not
impossible. When I built my Wright machine, the only easy materials to
find were the steel rod, sheet, and wire.


A few years ago I got involved late in a project to make Wright Flyer
replica wings. We covered one and left the cloth folded back on the
other to display the internal construction. The wings are now in the
museum at Kitty Hawk.

Some of the wood was ash the rest spruce. Ash is available locally
throughout most of the Northeaster quarter of the US, I don't know
where the spruce came from. I was told that the Wright Brothers
had theirs shipped in from West Virginia as spruce is not native
to Western Ohio. The cotton muslin was bought from a company
that made it for filter bags. We used Aluminum sheet nstead of
tin. I don't remember where we got the string, but do recall that
it was waxed and sticky.

I thought that was the whole idea of the lead. Wouldn't it offer
protection against mould, fungus and various tiny critters that want
to eat the canvas? I've often wondered if that was not also an
advantage of lead in paints.
