Crankcase machining ???

[Bluebird7]

I, like most of the commentators regard the casting as a 'novelty item only' Even if I had access to the machinery required it's still a daunting task.
I have a figure in mind to make an offer, but its a fraction of the asking price. It still begs the question why the caster, Mr Flake never supplied them as a ready to use item, just seems a lot of work for 'half a job'.
