[PSUBS-MAILIST] K-600 new motor mounts

[hank pronk via Personal_Submersibles]

Greg,The closest I have tested to your sphere was 48 inch by .250 and 516-70.  I was limited to 200 feet of water in Moyie Lake and I think it hit 190 with no problems.  I would have liked to test it to 500 and am sure it would have passed.
What do you have in mind for this sphere?  this sounds exciting.  Hank

 Hank,
I have a steel sphere that is 48" diameter x .320" thick mild steel. Have you ever depth tested anything similar?
Thanks,
Greg

Hi Jon,I can't see how your going to secure the motor to the channels.  I have a simple and cheap solution that I use for Elementary.  Just split an appropriate size pipe that matches the motor diameter then put slits in the channel for heavy duty ss hose clamps. weld the split pipe to the channel.   It is easy and looks professional.  You may have a plan already, just wanted to throw it out there.Hank

I've attached new motor mounts for the MinnKota 101's onto the aft ballast tank framework.  This puts them each at about a 30 degree angle from center-line which should work great for my "tractor" type control, however I realize now that if one of the motors quits I will be running around in circles.  I have the option of adding a rudder but am not going to do that.  I'll live with it for now and see how it goes.
The motors will be cradled in the 4-inch channel and held in with SS or Alum straps.
Jon
