Stuart No 4 Steam Engine

[f350ca]

This thing is eating up my precious time, bloody thing is addictive. 
The intake ports were cored in the cylinder but entered the steam chest too far apart. Had to cut the openings in toward the center exhaust port. That meant the valve wouldn't cover them.


Cut a thin slice off a scap of cast iron and ground it to .1 thick them cut the ports with the correct spacing. This will go between the cylinder and the valve chest.





Made the connecting rod today from the supplied casting. The drawing shows the journal split across the center, decided to step the joint to locate the haves rather than rely on the bolts.


Starting to look like an engine.
