Not sure why but I can only reply to my original post...so;
At Vratislav;
I tried both of your suggestions. Well, for you second one I removed all sails on one windmill then put them back on. It seems to insist on spinning one direction.

I think your second suggestion is the solution. Unfortunately I've built all of my 'machines' under one tower and was just trying to bring the remote windmill over and connect it. I may revamp things and see if that works.
