I'm pretty sure even Chester used to supply certain models in green, so I never mention makes unless it's clearly mentioned on the machine.

Rotary phase converters are pricey. The step-up transformer and motor are the big cost. The rest of the bits for a basic rotary aren't that expensive. A few big capacitors, and either a time delay relay (or voltage sensitive relay if you want to get fancy) plus some wire and terminals are pretty cheap.

I used to have a link to a website that provided kits, including the option for electronic capacitor switching, but I can't currently find it. I was always tempted to upgrade my rotary with it, to eliminate all the relay/contactor chattering mine does when I start the milling machine up.
