Thin solder is nice for doing delicate work since you can control the amount of solder applied with ease. The issue with solder is the thinner it is the easier it is to bend and deform while you are using it. MoTinkerGNome removed the lead from a mechanical pencil and Hacked into a 0.5mm Precision Solder Dispenser. This is a cool idea and cheap since mechanical pencils can be had for under a dollar.Â
