I made two, one is linear and the other is rotary. They work just fine but are under powered. I thought I could compensate for the low power by spring loading the members. This helps a lot, but in testing I find it inadequate. I bought a trim tab actuator that is fully submersible that I can experiment with. I hope to simply remove one o-ring from the shaft and air compensate it. One nice feature is the screw system requires no limit switches. The actuator is cheaper to buy than build from scratch. Luckily the new actuator is the same size as what I built, so they will fit the manipulator.</div><div>Hank</div></div></body></html>
