And I think this pump draws at least 45 watts. So ATM the running pump is the major heat src. I have a good sized (6") rotron fan I'll find a cord for, and probably hook it up to the pump relay to let it blow at a corner of the plastic tank. Good excuse for a long timeout on the shutdown. ;-) Then I need to find/make an ice cream or dishwasher pod tub holder to park the mister's src coolant suction hose in, just low enough on the side of the gantry to not be self siphoning. Lots less (in theory but see Yogi Berra's take on that :) tangled hose to worry about if it moves with the gantry. Besides that, the suction hose isn't long enough to put it in the drag chain beyond the X chain. I think its long enough for that... If not, its spliceable. And get me a gallon of mix base to mix into a pint of coolant a teaspoon at a time. There's no such thing locally, been looking already, so fleabay it is. Kool Mist, $45/gallon/w/free ship. Ouch. It seems there is also a kool fog, but its made for stage and theater fog generators. I'd imagine they don't sub for each other at all, but its only 26$/gallon. [...] Thanks Chris.
