Welcome to the Forums! Glad to have you aboard.
I'm also a member of the failing eyesight group and shaky hands. Harbor Freight has some optivisors pretty cheap. You could also get drugstore reading glasses pretty cheap. I use 2X when working at the bench and the optivisor if I need to get closer. Can't do anything about the shakey hands though. Those darn freight trains keep coming by under the bench every time I'm working there. Have to learn how to work around them.
I've heard a lot of good things about those Molotow Chrome pens but haven't needed one "yet".
Good luck and looking forward to seeing your builds.
Jim

I keep hitting "escape", but I'm still here.
