    It was very difficult to hang the links to leaf springs from bottom side. Especially coil spring unit is small and easily to be fragiled. For more easier to do suspension , assembly from top side is a way to solve problem. I think I should separate the chassis and tank. I'll do later on the beta-building version by volunteers.

    Magnificent work, Kooklik! The train guys must be drooling over this. I don't know how you keep getting better but you do.

    First brakes assembly. The brake rod is made of 1.4mm copper wire (same as coil spring).

    Hi to all
    I've just come back from short leave. Nothing much inprogress. I re-designed the tender truck frame. The old one was rather weak. I found this problem during tender millipede wheels building. I changed all paper thickness to be cardboard. It's so good result. The wheels & bearing aligment is exactly good.

    Hi there
    I'm back to the thread again. Added wheels and leaf and coil spring. It's not well finished yet. I checked each part aligment. All of them well fit as well as the digital model.

    Hi to all , thank you
    I finished the right side brake. A difficult and complicate section. Some joints are very small and weak. I must apply superglue to reinfoce them.

    Me too. I haven't posted on this thread before, (or the sub thread for that matter), as I am simply lost for words.

    Cheers JTF
