Hi, all. Just seen these posts, great clock malc75! If anyone fancies having a go at one of Clayton Boyers clocks please do. I have done the Horologium, the Tempo and Galileos Bicycle. I have to say I felt daunted by the gears at first, and fearing that everything had to be mega accurate, but if you follow the patterns carefully and with a bit of tinkering they are a pleasure to build and they reward you with something that actually moves rather than just sitting on a shelf or table like so many projects. Clayton is also very approachable via email to help with any problems you have with the build and asks for pics of your finished clocks. He is based in Hawaii but my plans only took 4 days to arrive....(eat your heart out Royal Mail!) The only problem I have found is I'm running out of wall space! Still scanning the walls to find a spot for the Marble Strike clock I am plucking up courage to order, without t'other half knowing!! Have a go....they are worth the effort honestly.
