Re: [PSUBS-MAILIST] Fill Fluids in Electric Appliances

Thanks Jens,
That data might also be useful to David Bartsch as it is specific to sonar 
transducers.
I did some tests with various oils placed in small transparent plastic 
containers & mixed
with water to see how they separated. I was surprized to see the container 
with WD40
in it disintergrate over about a week. I'm still using WD40 in my motors as 
I'm hoping the
plastic in them would be a bit more risistant & other people don't seem to 
have had any
problems. However the linear actuators are full of plastic & viscosity isn't 
such an issue
so I'll try the silicone.
Regards Alan
