[PSUBS-MAILIST] Closed view

Since drop weight release is potentially an emergency requirement I would not use anything other than a manual mechanism for it.

Jon,  i hadn't thought about those before. Would you use that drill motor for a drop weight system or stay with a manual system based on your testing?

Rick, consider conversion of a cheap rechargeable screwdriver.  I've been experimenting with Black & Decker Li2000 which is low voltage (3.6vdc), low rpm (180), has a lot of torque, and is reversable.  At $15 they are pretty much expendable and easily replaceable.

You guys got me thinking about these solenoid's but for a different purpose. I fabricated a cable/pulley system for opening and closing my VBT flood valve as it is under the floor boards and not in a convenient location on a K-350. Do you Solenoid guys happen to know about how much pressure a plunger can exert? That might be a great way to rotate the valve 90 degrees easily.Rick
