Hi Emile,
Firstly congratulations on the sub,
great work, must have caused a lot of interest to
the local residents.
A vial is just a name for a small
cylindrical tube. In this case it was
plastic, with a
plastic cap on top.
Maybe the plastics in electric motors are
more resistant to the WD 40.
I'm in the process of oil compensating a linear
actuator ( electronic piston )
Wich involves encasing the unit in fiberglass.
There are a lot of small plastic
components including 2 micro switches wich I can't
pot in epoxy, so now
after looking at what the WD 40 did to the plastic
container after about 3 months
I'm looking for another oil.
I'll have a look at the DOT 5 brake fluid & see
what it does to plastic,
Thanks Alan

compensating oil
Alan,
What is a vail?
One way plastic bottle? Till now I have good result with WD40 and
plastics.
New
material:
Somebody ever
considered Silicone DOT 5 brake fluid as used on motorbikes? Yes, DOT4 is
aggressive for paint etc. DOT 5 not and is thin as
water.
First drawback is
that it is expensive..

compensating oil
I was experimenting with various
organic oils & WD 40
for oil compensating my motors
& linear actuators.
I had a number of differant oils
in small plastic vials
& was mixing them with water
to see how it separated out.
Just found that after a couple of
months the vial with the
WD 40 in it went soft, cracked &
leaked. Can't tell
you
what the plastic was but its got
me looking for alternatives.
