[PSUBS-MAILIST] magnetic base

[hank pronk via Personal_Submersibles]

 Alan, Yes I will make a pocket to take the vertical force.  I think since the magnets are so cheap, I will just replace them when they corrode.  Maybe spray them with WD-40.   I did that with my hatch spring and it is amazing how well it worked.Hank

 Hank,If you could mount them in a slot so that the vertical thrust pushes against theedges of the slot, that would require less power from the magnets. ( you wereprobably planning that anyway). Magnets are corrosive so you would have to either coat them or mount themInside the hull. They should magnetise through the hull if strong enough.If the magnets were mounted inside the hull you may be able to knock themsideways out of the way to help release the thruster.I would have some way of pinning the thrusters during transport, & take themagnets off ( some how ) during storage.One thought is that a powerful electro magnet may help with the removal ofthe magnets.Alan

Hi All,  I want to make magnetic bases for my vertical thrusters on E3000.  The thrusters are mounted to the hull section that jettisons witch is bad.  I figure the best way to jettison the motors in my case is to mount them with magnets that will break away.  Anyone try this?Hank
