TIL that skipping a proper lunch during long installs leads to shaky hands and bad crimps. A dropped tool onto a fresh board convinced me to eat. | Avionics Technicians - Guest Forum
Makes sense. I've seen that with a lot of the same kind of work, taking short breaks to eat or drink really helps keep things steady. It's a basic thing, but so easy to forget when you're focused.
What are the other main things that cause shaky hands, from what you've seen @the_cameron? I've noticed stress and too much caffeine can do it for me. Figuring out the root cause makes it easier to fix.
