I'm looking for the simplest, most effective spool-holder for frame-wire. I've experimented with some different designs but still haven't found what I want. I'm wondering if someone here has invented something that's an improvement on the usual 2 upright pieces of wood attached to the wiring board with the spool rotating on a bolt through the tops. Different methods of preventing the wire 'birdsnesting' would also be of interest. With photos if possible.
