LED lights! I’m in my mid 50’s and my hands are steady but I I’ve had cataract surgery in one eye (I wear a contact lens in the other eye) and looking at things from inches away just doesn’t focus for me. I’ve been working on a Squier to Esquire Tele conversation and several extremely kind and patient people have given advice on the forum. I was struggling with my old soldering iron as it was taking forever to heat up. I looked at the handle and it said “Tandy Radio Shack 1988”. Ok then. I went to the hardware store and learned that most new Wellers have LED lights and they heat up in moments. I could see what I was doing. I applied all the advice from the kind guys on the forum and I think I could actually do some tight soldering now. Simple triumph.
