This may be a stupid question, but one I have thought of a few times so here goes. Does temperature matter when dimpling the skin? I don't know anything really about how temps affect how metal reacts when deformed. If it's really cold out when dimpling could that give a greater chance of cracks? Temps I was thinking were from like in the 30's on the cold side vs 70's on up.
Pardon this newbie question. Hoping a metallurgy guy might chime in with a little lesson.
Years ago, (more than 20-years) I was told that warming the aluminum skins with a heat lamp will make a smoother skin. I used a heat lamp on one assembly. I found it to be more trouble than it was worth and could see NO difference in the finished result.
Extra work, longer time to build, and NO improvement in quality.

To most people, the sky is the limit.
To those who love aviation, the sky is home.
Heating can assist in dimpling, depending on the alloy and material and what you are installing (rivets vs Dzus Fasteners, for example) . Not generally necessary for 1/8" flush rivets in 2024 and 6061.
From memory, 7075 and Magnesium required heated dimplers.
