Machining the
Cylinder Covers
-  for the Stuart Compound Launch Engine  -

(Part 1 - Upper Covers)

Top covers are simple in purpose and do nothing more than keep the steam in the cylinder.


Small steam launch engines often have round top covers as arranged for in the Stuart castings

However I preferred a more of a "marine engine look" as in a tug or small tramp steamer
