Even with that explaination, I just can't seem to get the spacing and the
gearing right between the dials. If you have the time, please, I would like a
visual aid of the between walls and the between-dials gearing. When I first saw
this, I thought "wow, sooo cool! I have to build one for my modest layout!".
Several months of tinkering with LDraw and real pieces, and I'm still stuck
after the first dial setup.
