So there are castings and patterns out there somewhere.
Someone must Know !!!
Well here's a 10 stud Ulster that I've nearly finished

That looks great Charles, have you been counting the hours you've spent machining the crankcase?
No, I didn't keep a log but if I had it probably would have showed how ridiculous the task really is.
An awful lot of time is spent in contemplation, working out the approach and sequence. In modest commercial terms I doubt that you'd get any change out of £7-8K for machining a one off like this. It would only make sense if you had the right CNC tools and could cast, machine and guarantee to sell at least half a dozen at £4-5K. The Austin 7 market doesn't support that sort of expenditure for a bare crankcase.
