White lead & castor oil on prop shaft?

While attempting to distract myself from 8 hours of filing documents
on Friday, I Youtubed up the Republic / Air Corps training film on how
to field assemble the P-47 Thunderbolt. (Where I work, that's called
multi-tasking.) In the film, they describe coating the prop shaft of
the R-2800 with the "perscribed mixture" of white lead and castor oil
before installing the prop.

Just out of curiousity, how would someone comply with this procedure
now? Castol oil is easy enough to get, but white lead? Substitutes?
And what exactly does the white lead do? Does it act as a packing or
anti-corosive?

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.

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

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

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...

Only ten men to put the prop on ;-)

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'.

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.

White lead used to be a wonderful anti-sieze outlawed many years back. I
expect I'm showing my age having used it in the past. About the same era,
carbon tet was used in fire extinguishers. :-)
