Hi David,
I'll be happy to help, however the seals that I am using
and familiar with are not suitable for high speed shafts.
I will help if I can.
Best Regards,
Jim K

Jim,
I plan a single 1" drive
shaft...I might need some advice on seals
later...

Hi Again Frank,
As you know, I'm a rotating shaft thru hull kind of guy but may still
have an idea for you that will not use electrical power or be slow. If you
used two similarly sized dual acting hydraulic cylinders, one as an actuator
and one inside as a master cylinder you could have direct immediate response
and no power drain.
Hope it helps!
Best Regards,
Jim K

Hi Jim. Thanks for the compliments. I'm getting ready to do the power
thing for the dive planes, and want to check out using electric before I
commit to air or hydraulic. I have a grainger's book, and there are lots
of motors that would work, but ya, I'd have to build enclosures. I'll
probably stay with hydraulics, but want to research this possibility
first. Moving the dive planes with an electric toggle switch would
make it more responsive to descend/ascend via the planes, but suck up a
lot of electrical power.
If I use a small hydraulic pump, the inside controls would be
basically the same as electric, but I was really planning on using a hand
pump, where quick changes in dive plane position wouldn't be
possible, but uses no battery power. Still looking for the right
compromise of power usage and performance. I have limited space for
batteries, and am trying to maximize the 10 battery "bank" so I don't
waste it on unnecessary tasks. Anybody out there got a small nuke plant
they're not using ? Frank D.
