Hi Mike, thanks for this, but if you knew anything of my track-record with DIY - and electricity in particular, you'd understand why I'm going to pass on the option to make my own!Mike wrote:Just use a piece of unwound guitar string, a push switch and a nine volt battery. Only switch on for a very short time.( Otherwise the wire will melt). You can mount the bits and pieces in a plastic housing, but you need metal terminals for the wire. The legs of a standard three pin 13 A plug are suitable. These things get very hot indeed. Be careful!
Mike
But thanks for the info anyway, always interesting to be aware of such things.
Andrew.
