It did throw up a couple of issues though. The chain seems quite loose when running, I'll try removing a link or two. Also, the engine only runs in one direction - this I was expecting, but for some reason I thought it would run the other way! This means the engine and flywheel are at the back of the chassis, not the front as expected. Could this be changed around by swapping the steam and exhaust pipes around? (nb. I really don't know much about this stuff).
Next steps will be to fit the boiler and firebox, and deciding whether to use the Mamod solid-fuel burner, or construct a meths one. The latter would probably perform better but would involve learning to silver-solder, so I haven't made my mind up yet. The bodywork also needs some thought; if anyone can advise what the best material to use for this is, and the best way of cutting sheet material (tin snips? hacksaw? jigsaw?) I'd be really grateful for the advice.

I found with sheet brass I could score it with a scalpel and the carefully bend until it snaps on the join. Can’t remember what thickness I was using though!
