    Hi to all
    Finished all front brake links. Very tough work ! Some parts I modified their shape to be buildable by paper. But links machanism is same as original.

    I am SOOOOO glad that someone is tackling this project. I tried about a year ago and failed miserably. I have been in love with this loco since I was a little child. Good ole #4006 is just a couple of hours from me at the Museum of Transportation in St. Louis. I've spend many, many hours sitting inside the cockpit of that magnificent beast. Bit of history on #4006...it logged the greatest number of miles of any of the 4XXX locos...1,064,625.

    At 1/48, if my math is right, the loco and tender should be about 2'-9" in length (132'-10" x 1/48 ). I think I might have to resize this to 1/24 to make it a bit over 5'-6" in length.

    Also, is it just me, or did one of the axles under the mover decide to give way in that pic?

    I wouldn't doubt it...according to Union Pacific Big Boys this thing weighs in at 540,000 pounds!!!

    Kooklik, if you want to make your model to scale weight, all you'll have to do is add 11,250 pounds of lead. :eek:

    How often do you see a locomotive going across a crossing without being on the tracks?

    Wheel dimensions

    If the U-boat, which I purchased, is any indication, we should be in for a real ride with the Big Boy. One request, if possible Kooklik, include actual dimensions in your drawings for items such wheels, boiler covers, gears, and other round parts. It saves the time of having to build them.

    I have tired of assembling round parts which look clunky in paper anyway. As an alternative, I have begun turning masters on a lathe, making a mold in RTV, and casting them in Celluclay.

    Hey, it's paper!

    You've made me remember out a scene from "Enemy At The Gate". They mounted 2 T-34 terrets on a bogy infront of the steam engine.

    3D see through color mode is a normal feature in Rhino4.0
    press ctrl+Alt+G (Ghost Display mode) your surface/polysurface objects will be see through.
