Thank you for all the kind comments :)     This next "episode" will have all you Real model engineers shaking your heads :rant:    However the system suited my equipment and ability.  I rescued the hub of the drive pulley and re-drilled the holes such that the new spokes were an interference fit. I then put a countersink in the spoke holes on the outside of the rim. Set up in the jig, the spokes were knocked home and the stick welder used to spot them to the rim. Back in the 3 jaw to lightly bore the hub concentric and then file flush the welds. A touch of JB will tidy up and not be seen under the paint. I am pleased that I used the cast iron piston ring as I have located a boiler and should be able to steam it before long. Current work is cylinder drains, which apart from tap ends are hidden below the cylinder inside the bed.     Terry

A little more done to the pulley.   joining plates for the two halves. A new slitting saw is required to split them, so I await the post.       Terry

I have reached "almost complete" with the engine. Since the pics were taken I have made the cap for the lubricator and started on some handrails. A bit of tidying / painting is needed, but not a lot. I am awaiting the arrival of a boiler so when steamed it will get burned and oily and look a bit more real. In the earlier video the valve timing was set "neutral". After making and fitting a new piston ring I advanced it about 0.003 so that at top dead the ports were just starting to open. It doesn't run as nice now on air. I hope that when it's on steam expansively it should be fine. (similar to my Burrell which runs great on similar principles)                        Terry

I have reached a point with this engine where I consider it "finished". No steam yet, been too busy to sort the boiler.     That's all folks.
