[Premium-Rx] Nylon gears

[Jerry Kincade]

Hmmm... Never realized that. Would a long soak in very light oil (maybe such
as penetrating oil?) be even better, and last longer between soakings?

Hi Guys:
Nylon needs to have moisture in its chemistry to stay srong & resilient. Age
drives out the moisture and the stuff gets very brittle. Model airplane
builders discovered this decades ago and there have been instances of
shattering props.
So, they would place the props in warm water for 24 hours or so and restore
the moisture content and a return to a non-shattering state.

So I would think the same could be done for the gears under recent
discussion if otherwise they are in good condition. By good condition I mean
not cracked. If its an old gear it looks good but does not have the strength
it had due to drying out. Give it the H2O treatment to preserve its
continued strength.

For what its worth.

Cheers,
