Screwing in the stud bolts for the steam chest, ( valve box ).
Steam chest in place with the valve gear and Eccentric Strap.
Steam chest complete with cover bolted on
Front quarter view.
Originally I was going to run the engine and prop from a double shafted motor, but I got to thinking that might be too fast for the steam engine so I decided to run it from its own motor at a lower speed, I have plenty of universal couplings but because of the space available I made a simple drive coupling from some scrap brass etc that I had handy, turned a piece of brass for the steam engine part of the coupling.
Shows the part attached after drilling and tapping it for the grub screw and also one of the arms in place, you can also see one of the two oil cups in place on top of the bearings.
View of the finished coupling, the arms still have to be cut down to size.
This is the other part of the coupling that attaches to the electric motor, it has been turned to size
and drilled for the arms and the grub screw.
Shows how the coupling will work when finally located in place, the electric motor will be hidden
inside the dummy boiler.
Close up view, when working it will be more evenly aligned. and the arms trimmed to size.
