This project is really starting to come together Chris. Have a nice Thanksgiving. Hopefully it isn't too "weathery" back there.Jim
great how to on the eccentrics,, will most likely be turning some in a few weeks..
Thanks Don Looks like the next project will finally be the Stanley engine! I've been trying to figure out how to do the engine block with the center steam chest, with the small openings to the valve faces. After a number of false starts,
Got the rest of the studs/nuts in place on the bases, so its time to turn my attention to the eccentrics. I looked at the stock I have on hand, and there is some steel plate stock that will work for the followers, so the eccentrics were made from some bearing bronze rod. Started by turning them to diameter and cutting in the center slots for a rib on the eccentric to sit in, to keep it centered. Then switched to the 4-jaw chuck and dial indicator to offset the parts by 0.125" to one side. Drilled/bored the shaft hole to fit the crankshaft.and turned down the side to form a boss for the set screws to hold it in place.Here is where it will sit on the crankshaft, still need to drill/tap for the set screws.

After a number of false starts, Chris did you post the arrangement for us to look at yet? Might be able to figure out how to go about it like doing it in three parts. Regards Don
