[hank pronk via Personal_Submersibles]

 David,I did not modify an existing electric actuator.  I modified an air cylinder by installing a gear head motor inside with a threaded rod.I am loading a video on youtube right now so you can see the performance.  I can make you a couple when your ready and I have perfected them.  I have a pressure chamber plenty bit for the actuator that can test to 5,000 feet.Hank

Hank,  how did you modify it? Have you tested it for depth rating? I need a couple for 600 ft and a rainy day project.

 Hi All,Here is a picture of my first electric liner actuator that is fully submersible.  The actuator can lift 50lbs  at 1 inch per second approximately.  The actuator cost me 50 dollars Canadian to make.  This one has a 4 inch stroke and is well suited for the second sage on the manipulator.    I can either air compensate  or oil compensate the actuator.  I can also put 160 psi inside permanently and use with no compensation to an undetermined depth.  Hank
