I’m lucky, in that the doors on my shop, the old hangar, open wide, providing a 38 foot opening, on the East side. Our prevailing winds, plus a fan blowing into my usual work area, help keep the temps tolerable.
Even with that, I usually work in the morning and evenings, using the heat of the day for napping, etc. I keep a Bubba Keg jug, filled with ice water, handy at all times.
