This is a problem that anyone involved in this mad hobby of ours has to endure on a daily basis. How many times have you been about to fit that tiny but vital part using your special fine-pointed tweezers when you've heard the dreaded sound -ping! - and it's vanished.
I can't count how many times my wife has come into my room and found me on my hands and knees searching in vain, Quite often she joins in, even though she has no idea what she's looking for...
I would like a tool, a plastic magnet, if you like, that attracts the missing parts. Something that can locate plastic and resin parts would be for me the invention of the century.
