Some progress on the traction engine.
Wheels done just have to decide what I want to make the rims/tyres from. I have some nylon but maybe aluminium? Brass was the plan but $400 for hollow bar has put that out of contention. Bit of colour coding, plating and working out if I want to put a roof on it. And of course chuck some thread on for the steering chains.
And it is all wired up. Battery box is in the water cart. Works goodly even if the wheels probably are a bit low geared but who cares. Now I am happy with the proportions of the water tank I will make a new chassis from red lego and I have white tank bits on the way to finish that. And some tiles to put around the centre so I can make a filler in the centre. Water tap on the back and chains to hold the tank on worked out well and I should have some lego bits to put some hoses on there.
