Re: Bryans Worlborl

Progress on the Worlborl is a bit slow at present as I am waiting for a friend, who is currently working abroad, to saw a length of oak in half as my bandsaw is not powerful enough to cut through six inches of solid oak.
I took some photos at the Elephant House ‘Bryan’s Viewing Day’ and there is an interesting difference between the earlier Worlborls and those made later. In the early machines the timing device necessary to allow the release of all the balls is done by the coin locking down the release lever then running across two tracks to unlock the lever again and reset the release pin. In the later versions the timing is achieved by a coin carrying a counterbalanced arm down to release the balls; then dropping the coin at the bottom the arm returns to the top so resetting the release pin. Much simpler and far less work to manufacture.
