Not being adapt at either metal work or joinery, I was pleased with the result whick works well too.
The key is made from a bar from a door handle as the main moving part, a u-shaped piece of aluminium, a cheap wooden cupboard door knob, some drawing pins for contacts and a few nuts and bolts. The base is a piece of hardwood, stained and polished (shoe polish!).
A groove is cut on the underside of the base to hide the two wires from the contacts. Drawing pins are used for the latter.
The iron bar from the door handle is handy as it has holes in each end for the knob and the contact nut. However a hole had to be drilledt for the centre support.
