i was looking at some web site about the crosley engine
notice that cylinder and head section was made of brazed sheet
metal but not the crankcase and i was wondering if it is possible to
build an engine about the size of a 8 hp Brigg and straton
out of steel or aluminium sheet metal ( for cylinder block and
crankcase) and tubing( steel tubing for cylinder sleeve cyl,head ports)
yet some parts still be made in billet it would be water cooled and
overhead valve or flathead it would be a nice project with the right
machine tool ( milling , metal lathe ,ect) all sheet metal arc welded
then machined i know that GM EMD diesel locomotive engines are done this
way and some european diesel truck engine like MATRA ( there V12 engine
block is made out of steel sheet metal) does some knows if it as been
done for a project

'Don't know if it's been done for a project, but there are other
commercial/professional examples. The Mercedes-Benz Grand Prix engines of
the late 1930s were welded. And GM revived the idea of a furnace-brazed
engine, like the Crosley, in the late 1970s. It was never built in
production, but I saw one and all the parts at a SAE show around 1979. The
parts were stamped.

There have been other welded racing engines but I can't remember any
specifics.
