We've discussed trying to pull off aluminum pulleys, but I haven't yet identified anyone to do it for us.

... If the Harrison shop hadn't sold off their dividing head years ago, you'd be in luck (although that would be a LOT of manual milling). When you have the right machine tools, anything is possible.
