Have one of those Steam and Sterling books. Looked through it for something to make. The 3 cylinder wobbler looked good, "hey I can do that with what I have" wrong!
Maybe a 2 cylinder, wrong again. Good thing this one worked, I was running out of cylinders. The bride would say that happened a long time ago.
Drew it out trying to keep it within the old "Golden Rectangle" bit for eye appeal. I just find it curious why some things just look better than others. Probably should measure out the final result to see how far off the end results were. Have noticed a lot of the Elmer engines seem to fit within these boundaries, got to be some reason they are so well liked.
Was a good learning experance. Can appreciated the talents of others. Cranks a one piece, lots of thump thump thump turning that down from a hunk of round. Cylinder, pivot pin also a one piece, a 2x2x4, thump, thump, thump. I sure see why a lot of soldered build ups are done, but I always make the easy harder than it needs to be.

Practice hitting the numbers a little, and you can make press fits. Especially for stuff like the crank pin (dowel pins are cheap), and no soldering necessary. If you miss a bit (too loose), there's always loctite. Too tight, and you hit it with a bit of emery paper.
Hey, If I can consistantly make a good press fit, just about anyone can.

Getting better at that. Got the little lathe "tight' enough to pull off that last little half a thou cut. Sequence of assembly is another. Exampled, flywheel web to be fit into the rim with the hub fit into the web. Did the web rim combo first (heat chill), wrong!
When the rim cooled it caused the little collapse seen in the shot. Live and learn. For a 4 inch dia flywheel.
