It is entirely possible that a delay may occur, the date is very much an estimate only and not a guarantee.
The long-awaited sequel to Felix Ure's Piston is here! Piston II is a challenging, six-stage, sequential discovery puzzle. The aim is to remove the steel ball from the top of the puzzle. He rates it as 7/10 in terms of difficulty. Machined from solid brass, Piston II weighs in at 1.1kg and measures 138mm. The brass has been intentionally left unfinished, leaving it to slowly patinate and darken with use (unless polished of course).
