[PSUBS-MAILIST] motors

[Alan via Personal_Submersibles]

Brian,
the aluminium is another issue. I had to go with a stock size thick walled
extruded aluminium tube, that I machined to the correct diameter inside
& out; & a solid rod for the front & back housings. Not cheap. The Minn kotta
housings are cast & as such there is a saving in size & material. Then there is
the anodising!
Cheers Alan

Talk to them today and they're going to give me three motors for some honey.   They literally have 50 to 60 golf carts in their boneyard with motors at any one time, and they are constantly dumping them into the a giant roll-a-way bin for pick up.  I may try to work a deal with them to get some more.  Most of them are 36 volt.
