Re: [APD] Re: Vortex HELP! -- No Fan!?

I checked the spec's on my motor.  It's a Hubbell Special Productions motor,
1/40 HP, 3k RPM.  I've checked carefully inside the motor unit itself, there
is definately not a fan inside the motor from what I can see, and as Scott
said, the shaft protruding out the end of the housing would imply there
should be a fan on that end under the motor cap.  The date code would imply
it was manufactured Aug. of 2002, also in line with what Scott said.
Personally, I don't know how this man tracks and remembers these minute
details of one company, but it has paid off here, thanks Scott.  Susan also
offered to take some pictures so I could compare her model with mine, in
this case I must say thanks so much for the offer of extra effort, but I
don't think it'll be any better then apples to oranges ;-)

I tried calling thatfishplace.com tonight, but they directed me to Customer
Service which is only open 8am-5pm EST (naturally overlapping with when I
work ;-).  I'll try to get a hold of them tomorrow during the day to see
what they can do, I'll be sure to update the list.
