I am certain Merlin crankcases (and cylinders banks, heads, accessory and supercharger housings)were cast, then machined.

Looking at the outside of the Merlin crankcase it appears quite rough, as though the mold was "carved" out.

I vaguely recall that a mold for a Merlin crankcase wouldn't last very long, and would have to be replaced every hundred castings or so??

I know that Allison V1710 engines had cast crankcases etc, and that their cranks and driveshafts etc were steel forgings that were heavily machined.

This subject has got me interested now...will try and do a bit more research.
