Just the thickness and central section left to machine. To give you an idea of the actual size, the bores are 28.5mm between centres. Next is to turn up the phosphor bronze bearings and press fit them into the bores. I'll warm up the aluminium first to ensure a tight fit. Then I'll finish bore the holes to 6mm dia. to suit the crankshaft and the other end to 5mm dia. to fit the gudgeon pin.
