I think it was wrong to pretend this was a public service announcement. That makes it fake news. I have no issue with whatever hypothesis anyone has as long as they are honest about it.
Not at all my intention John. Never one for fake news but they clearly aren’t using one contiguous piece for the whole body. It was wrinkle at bends / corners I’d assume?

Wonder what kind of surprises there will be at the unveiling announcement

I think Tesla will be mimicking the aircraft industry by joining the bent panels using industrial strength adhesives. They may employ the use of jigs to get perfect alignment every time. Welding SS would cause distortion and change the color of the steel.
They've been practicing with advanced welding robots and weird techniques at SpaceX, and those have become more precise as they go.

Exactly! There will be robot welding, plenty of it (but far less than traditional truck frames). There will be some glue but I don't think it will be relied upon very heavily. They might use gluing inside the outer panels where they need to attach things in areas that discoloration would be problem- or where they need a dielectric connection. In most areas they can weld where the discoloration would not be exposed. Welding is still the best way to join two pieces of steel whenever there is not a good reason to avoid welding.

A bit of a zoom in on the brake @greggertruck posted above. Kind of a low-res shot so hard to get much, but it certainly looks like big steel brake.

They had the press area up first with the Y first, but I feel like this bodes well for late December early January demo / scrap trucks.

FWIW. My limited understanding about vehicle engineering is that trucks handle most load in chassis which I expect will be stamped steel by the IDRA press for CT. The body panels will provide structural support as needed for as a "safety cage" but most of the strength in a vehicle us required in a chassis. ¯\_(ツ)_/¯

IDRA Gigapress creates aluminum castings, not stamped steel. (This Is I think a front casting for a Model Y)

The casting will support the load, but the truck needs rigidity because the weight of the load is distributed across all 4 wheels.

Most vehicles don't use a ladder frame anymore, and the strength comes from the body. Yes, most trucks don't do that yet, but most trucks are built to be made cheaply. Cheap can mean 'no new technology' in some features m too.

I wouldn’t put any money on the @greggertruck idea and will gladly eat crow if I am all wrong.

I wonder what crow tastes like...

not a brake. It is a stamping press if you believe the guy that took the shot.
That's no a stamping press, it's a gantry crane lowering the base of the press/ brake / elons Twitter server cluster.

gantry crane of course. No one would question that. I challenge the notion that there would be a brake being installed there when no such brake has been delivered to GA yet. I posted some links to possible brake manufacturers and nothing that could handle the size (length and material thickness) of the CT has been delivered. You are welcome to your conjectures; I just don't believe it.

Doesn’t quite look like the other stamping presses. Looks more like a brake.
