Well I disagree that good eyes are required, I have terrible eye sight and with the aid of a digital Camcorder mounted above my work surface, I use my monitor to aid my weak eyes.
As far as peices flying off… >sigh<.. I am open to any solutions, my practice right now is to cover the item with stretch wrap, I can see through it and it catches everything that "takes off" on its own. I only use it when I am setting "spring loaded" peices, like the stem set spring on a 0/3 Waltham Ruby movement. Chased it around the room several times before I came up with this solution.
