Hi there I missed these responses with being * busy around the garden * volunteering contributions at the hobby mine (have Eimco 12b - need to dismantle it and get it down the shaft and some bolted connections have been welded-up) * mind caught up on a line of thought about rock crushers. What Jim describes about optimal - at night, open window or run A-C - is the concept I was trying to convey (and Jim conveys much better). How much moisture the air * could hold *. In a foundry where there is a >locally< higher temperature with nothign else adjusted to create a new equilibrium, the hotter air * could * hold more moisture and when you perspire that perspiration * does * evaporate. So you get the cooling effect of perspiration. If you were to mist yourself and your clothes with water, that would presumably help - and reduce the amount you are covered in salt encrustations from sweating ?! :-).
