T1 and T2 Endoskeleton Research Thread

Time to resurrect this topic. The temple inserts. :)


DeltaDesignRus posted his findings in this thread. I'll see where he started that and post the post link here.

If I can make a lightweight endoskeleton with vacuum foam.
I think it can be made into a Bunraku puppet.
If it is made of transparent board, it can be painted metal color from the inside.
Printing it in PETG may be better than vac-forming. It's lightweight, but strong, and retains details better than vac-forming.
 
Got a pass of all the universal joints in today. I'm not going to pretend that I know 100% how the real parts look. I've never found the source hardware, and reference is slightly conflicting. So this is currently my best guess/take on those vintage joints:

I didn't mention it before, but I'm also assigning materials to each piece in Fusion as I go. I'm trying to keep track of what makes the T1 Endo so visually interesting. It was truly a more "multi-material" looking execution compared to T2. So I'm currently using 3 main materials - aluminum, a darker steel, and polished/chrome. I think it make a big difference in getting the right feel.

If anyone is interested in complex 3D projects, it can also be useful to keep parts/components organized and separated by colors. I intend to simplify and combine parts for printing/molding... but here's a look into how many separate parts I'm currently working with as I design this:

Fun!!

Looking cool. I joined my top and bottom pistons, as well as the piece between them and the fork out towards the toe into single models. The Lightstorm endo feet looks like all those parts are fused together. The T1 may be separate the way you split things.

One question though, are the angles of the outer toe forks not a little too steep? And I still think you should make the angle less on the big toe than the rest, so that that one lay almost level with the ground when attached to the ankle piece.

I think my ankle difference between the big toe fork and the rest were 2.5-5%.

Another thing, the forks attaching to the ankle piece doesn't seem to all be at the same height, and it seems they slightly curve the farther out towards the sides you go.

Thanks, I’m not done posing everything yet. I had planned to adjust the toes some more. The toe posing is also variable throughout scenes/films. I agree that the big toe lays more flat and that the angles change going down the rest of the toes. I’ll be picking a pose that I personally like. I’m not a fan of the “All toes lay totally flat” look that seems to be how all replicas have been made. The toes don’t look that way in any T1/T2 shots.

And yes, the upper mounts for the toe forks/clevis pieces are not all welded on “level” or straight. It seems on several screen used feet I’ve seen that there is some sloppiness in how they were attached… or maybe that slop is what was necessary to get everything aligned they way they wanted to. I don’t know. I’d like to take a crack at adding some of that “organic” feel as well. I just needed to get to this point where I can see if mechanically everything is roughly working in harmony before I try to add another layer of complexity with all the nuance.

Oh yes. The only toe fork that should be almost level to the ground is the big toe one. But it shouldn't be exactly level. I love that you plan to add in the wonkyness and not straight look to the assembly. Am in awe of the progress being shown.
 
Sadly, they did these a long time ago and I was lucky to get this one, as they are getting really rare to find. The ones you see on eBay and Etsy are poorly made recasts.

You could 3D print your own with pretty good results.
Definitely doable with a quality 3D print. A member of my team does some excellent 3D modeling, printing and finishing work. I may have him look into doing this - T1 and T2 never die! ;)
 
Controversial Bomb Drop: I am starting to doubt that those "snake eyes' security screws were ever used on screen used T1/T2 endoskeleton feet. I keep looking for proof in the reference and I cannot find a single image that CLEARLY shows these screws were ever used on the feet. As I'm doing another pass on my feet and improving them greatly, I've stumbled upon some reference photos that I took in 2023 that has me questioning why we ever believed that these types of screws were accurate. I will show them in a little bit.

I know these weird screws appeared on replicas endoskeletons, but prove me wrong and show me undisputed proof that these were on the original(s) from T1/T2. I have a feeling I know when they came to be used, and I think it's not until Icons... Discuss! :p

Aren't they on the endo from the scene where it's lying on the ground? That one has the different foot pistons and toes we see on the LFS castings and other fan made and licensed. I need to go back and check the pictures posted here in the thread.
