Thanks for all the nice comments guys, much appreciated.
Graham, I'm not sure about the paint, I'm kind of liking the idea of just leaving the aluminum bare, except for the flywheel which needs some body work and color.
Jason I have attached a photo of Myfordboy's engine mounted on the cast base. This is pretty much what the original cast base would look like. The wood base wasn't anything fancy, pretty much just a slab that the engine was screwed down to, photo also attached.
