So. I wasn't going to give any more commentary on how things are going with the build, but I was so pleased with this discovery, I just had to share my glee with you. Well it's back to the work shop again.
There are a set of clues that I haven't published yet but which are, in many ways, more informative than the ones I have discussed on http://www.theorffyreuscode.com/. As I suggested above, look for errors by the inventor. They turn out not to be errors at all but clues as to how the machine was constructed. The trouble is, it isn't clear what they mean until you happen on the right design and then afterwards when its too late, the meanings become clearer.
Then there is the 'Toys' page, a collection of drawings which show you various details about the mechanism. 'A' for example shows the mechanism before it has moved, notice the horizontal lever mounted in a slightly off set way.
'B' shows the same mechanism but a different part of it - after it has moved.
'C' and 'D' show two clues each, not difficult to grasp. Each mechanism has one weight up and one down, and each also has two sets of levers somewhat in the form that you see them on the page.
'E' connects those two parts of the mechanism, which is why it falls roughly between the two.
Too much already!
