Engines > Your Own Design
Chris's Slew-Crowd Engines
crueby:
Got the first four cylinders shaped on the outside, these are the Marion on the left and the Erie on the right. Right now I have the first of the Bucyrus cylinders chucked up in the lathe...
So far the production line approach is working well, with the common setup and process, the second pair went pretty quick!

I like the assembly line method you're using for all 4, Chris. And I like all of the engines a lot, but for my own odd reasons I particularly like the Thew. Surprisingly compact and simplified, almost like a model itself. True, it's smaller displacement than the others so naturally smaller package. But just seems like compact efficient design, too, so I like it.
Keep on turnin' :cheers:

Thanks! Not sure I have a favorite of these (yet), but for the hoist engines I really like the Erie - it uses a lot of the same features as the slew/crowd engines. The Thew engine is very compact, which may make it wind up being a harder one to build. Being between the cylinders, they arranged the cylinder valves so they are on their sides, up against the sides of the cylinder, with the throttle valve being horizontal in the center, so three seperate valve faces, with a single steam chest spanning them all. Should be fun!

I hope so! They will need the crane to lift the 5 gallon bucket under the dust separator connected to the shop vacuum, its about ready to haul away.
