Mike M, thanks for the tip on the portable AC unit. I just started looking at them and air intake-exhaust was something I was considering. I was thinking in terms of just having it blow on me in place of the fan. Not ideal but maybe better than a fan. I have a window unit at the local airport that I use when working in a confined space. It helps. I may have to try it out in the shop

Living out in the country I get the occasional power outage. So I have 2 window units in the house. I run them by generator when the power goes out. Fortunately they are on the backside of the house. So, mostly, the birds, deer and cows get to see them.
