    The real fun will be the steering, which will have to be proportional, with the treads on the inside of the turn rotating more than the outside treads.

    Here is the photo of my track pieces idea. Lego track pieces.
    According to my calculations, 1 1/2 inch width is perfect for SS. Any input? Am I off on the sizing?

    Well I like going precise on my builds, only allowing some artistic liberty with straightening some things out. So I'm actually still on the fence about using another kit as a basis, which will probably only have small differences compared to the Tamiya Sherman.

    Even though the sizing might be ok (haven't done any measurements on the tracks yet), the details will be way more of that i'd be comfortable with. Also note that the tracks had an addition to them so were wider than the kit parts themselves.

    Cheers,
    Marvin

    Hey marvin!

    That part was from AMT 1/25 Kenworth K-123.
    You need two kits.

    Thanks,
    Eric.
    Hi Eric
    would you happen to know the parts in the red squares?

    Yes that's correct. The original tracks were used but with extruded extensions fastened to them to make them more wider and help support and steer the prop.

    So next stage. I have MOST of the basic skinning done. Some skins remain and need to wait for panel application on adjecent panels.

    Wow. Beautiful work. Some of the angles are crazy on that thing.

    Thanks! They sure are. Took quite some time to get those right in 3D.

    Wow. Looks amazing!

    Very cool seeing it in unadorned plain white, really shows off the shapes and angles.

    An amazing start Marvin, looks the business. What sort of glue are you using to stick the styrene to the MDF?

    Thanks guys! I used a very strong two-part urethane glue that comes in two cans and has to be mixed 1:1. Rough up both surfaces and stick on. Very sticky stuff. Easy to clean up (while not set) with acetone. Only downside is it takes 4-6 hours to set up and 24 hours to harden out. But since its only needed for the first layer of skinning that's fine. I just did every surface so from now on i can just used styrene bonder.

    Cool project and great start. Hope I'm wrong, but most everything Star Wars isn't easy. I would be surprised if the Lego track works. However, did t Tamiya make larger scale motorized tanks. I would think ILM used something off the shelf for the treads.

    Yes they did. Sherman 1:16 is what they used off the shelf.

    Thanks guys. Progress is a bit slow. Lots of stuff to prepare and tidy up on the underside. Hooe to finish that up this week so i can move on to panelling and detailing each section. Thats where the fun is....

    So the first of the section is basically done. Others have been plated as well. Every plate cut by hand and tried to match the variations in panel spacing with the studio model. Face looks a bit slim but it will get a 1mm plating layer on both sides which will make it spot on.

    Thanks man. Im just making this up as i go along but having an engineering background helps.

    I just wanted to have as little room for deviations between 3D and the real life build.

    So next stage. Both front sections are basically done. Work has started on the sides and should be finished in a day or three.

    Since I'm recreating the 1977 version of the model there's fewer parts on these sections than what most of us remember. They added a lot of parts to the "throat" section fro the Special Editions.

    I'm still missing one ID: the binoculars. If anyone can help with determining which kit they are from I'd be most grateful.
