Probably newer construction. Many of the pieces appear to have been made on a milling machine and they started to come into use in the 1930s I believe. Most of the older engines were principally made with castings. I would look to see if you can spot any circular swirls that might imply that the part was made with an end mill on a Bridgeport or on a milling machine. The other thing to spot is whether many of the long structural pieces have long stroke machining marks that might infer that they were made on a shaper which is the older way of machining. Steam chest covers face each other. I've seen them in photos of engines but not in any original old steam automobiles that I know of. Also I believe the engine operated laying down due to the oil holes on the crankcase pillow blocks and the ends of the rods. I think your engine is newer, fun construction. Leave a Reply. |
