Hi all
Not sure if this is of any use to anyone but I've built a SketchUp model showing the basic arrangement of the Ormerod 2. It doesn't have all the bearings, wiring etc. but shows the arrangement of all the printed parts. I put it together to make sure any new parts I designed will fit.
If you want it it can be downloaded from Thingiverse at [

Hope this is useful to someone.
