So I dunno where folks get these crazy ideas sometimes. Hehe.
I wonder.... You're starting with a new box so there's no reason not to modify it some, right? I wonder if you could mount a pulley 1/3rd the size of the machines belt track on the base and have that driven by the window opener? It would have to either sit further to the right and drive a longer shaft or maybe forward enough to clear the balance wheel, in which case it could be nearer the machine. Any machinist out there?
