Re: [PSUBS-MAILIST] Problems with initial

Alec did more or less the same after we talked about it. Did you ever do a before and after amp load test? I'm curious about the friction/turbulence losses with the motors in oil.

Hi Vance,
 
I’ve always filled the motors with light oil and forgot about them. I just drill/ tap the motor housing for a pair of small barb fittings and connect them with a loop of clear tubing (make sure you get tube that stays flexible in cold water). The oil with travel through stranded wire so you’ll also have to strip the insulation back on a small spot, solder a small area and then pot the wire with a urethane or epoxy compound. As for the oil, WD-40 works great- It displaces water and won’t attack electric insulation or rubber seals. There’s always talk on the internet about fear of metal shavings getting in the oil but as far as I can see you just get a little suspended carbon and it doesn’t seem to have any effect on how the motors run.

Hey Greg,
The K350 is pretty close to ready for sandblast and paint, then it's down to wiring. Probably all summer to get it hung back together, what with all the rebuilds, including the thrusters. I'm still hemming and hawing about the Minn-Kota package. Carsten and Emile are working up some stuff on installing spring loaded ceramic seals on trolling motors, which works well on the Minn-Kotas, but I'm running out of time here and may just go ahead and whack everything back together rather than reinvent the wheel. This one I've got has the 3hp aft thruster, which is a pain as it is direct drive and runs a small prop, but hey, it's already on the shelf, so why not use it? Then the second boat will get the Minn-Kotas. That one is the 1000' hull with big windows.
Vance

Vance,
How is your boat coming along?

Scott,
The plans specify all dimensions and measurements for metal on the boat. Each sheet has a materials list. Or at least every sheet I have ever seen. You shouldn't have to be taking anything off the prin t with a ruler.

I am trying to get all of m y metal ordered for the main part of the sub (k-350). I am having a real hard time gauging the blueprints. I was wondering if anyone had a list of measurements. I am going to order the main vessle and ribs, two battery pods, conning tower and hatch, and VBT. I can't seem to get the plans to scale because they have been saved in PDF and were compacted before they were saved and they have no measurement scale except 1/4" equals 1' which doesn't help if the files have been compacted. HELP?
Thanks,
Scott Waters
