Get a set of rollers and work on your technique in air conditoned comfort.

For years I didn't have a house with A/C so the heat didn't really bother me, just slowed me down a bit. 107 is doable. FWIW we measured the Heat Index on my jobsite the other day at 135 degrees

needless to say, not much work was going on. Looks like time to move to night shift for a while.
