The 'do-it-yourself' process of making tiny valve cocks

Nearly the last thing to be done was to make tiny valve cocks. I first made a jig on which I wound sewing thread to create six radiating spokes, each consisting of a pair of tightly stretched cords. The outer ring of each gate valve, fabricated from metal wire, was slipped underneath the crossed threads on the jig and the whole thing glued together using super glue. Paper was carefully pasted over the string spokes, to create the six spokes of the valve cocks.
