[acropolite (Phil)]

I've yet to mount the focus motor on my ED80, included in the kit is a blank plate which needs to be drilled to fit the focuser shaft in my case Dave also included some spacers which he thinks may be needed for my SW focuser.
The focus motor attaches to the focuser shaft with a flexible coupler.

Here's the diagram of the focuser mount from the documentation, I'll add a couple of images once I get the beast mounted.
