[PSUBS-MAILIST] submersible motor

 Brian, I have an expansion bladder that doubles as a compensator.  I used a car suspension air bag.  You need a large enough bladder to allow for the actuators volume change when going in and out.  It is not that much really and you can also tie thrusters into the same bladder.Hank

 Do you have an oil compensator on those actuators?

 Brian, that is a nice robust looking motor.  Check the rating for water proofing.  That electric penetrator looks weak but might be fine.  You can always make a penetrator to replace that one or possibly a Blue Globe fitting would go light in there.  Alan is right about the strength, but you can cheat on that point.  Just spring load the arm to take the weight and let the motor just cause the motion.  I have done that in experiments with this type of motor for arms and it works but is a bit cumbersome.  Really in my experience, the up front cost savings disappear into time and effort.  I am in love with the Lenco Actuators.  They have 750 lbs of pushing force.  They  are very easy to oil fill and you can buy them used or out of the package on Ebay.  Hank
