I have an R1T and have noticed major oversteer when near lock while using the highest two suspension settings. This is no surprise, most people that have lifted trucks notice this due to altered front end geometry from stock. I had the same thing in my lifted 2500HD. I will say, the Rivian’s...

The only difference between 2 rear casings and 1 are the cost and manufacture time. They would essentially be the same strength, one casting would just be quicker/cheaper.

Model Y went from 2 rear castings to 1 to get production going early. Maybe they are doing the same with the Cybertruck? Start production with 2 castings with the available presses and once the big mama is available go to a single casting. Also, it would be very tough to cast this as pictured...

Looks 100% legit to me. I find it interesting how much space there is between the two rear frame rails. It is also missing the typical cross-members you would expect. It is painted so I think they’d be installed at this step in manufacturing. So this brings up the question, what’s going to...

The fact that Panasonic is moving forward with the 4680 would suggest that the 4680 is absolutely viable. They have obviously had their best engineers look at the technology and commit to moving forward with it. So i have no don’ 4680 is good tech. I just think mass production of the 4680 is...

Yeah, I agree. I don’t expect a 2170 Cybertruck. If the 4680 isn’t ready then production will simply be delayed. It obviously doesn’t make sense for Tesla to manufacture a 2170 Model Y at Berlin/Austin for 3-6 months then switch over to the 4680. If 2170 Model Ys roll of these assembly lines...

If Tesla had an extended cab then they could even dedicate the lower half of the extended cab to a Rivian-style utility tunnel since there would no longer be room for rear seats. Or even better for a tradesman, a pull out tool box. Maybe even recess the tunnel on both sides so there’s room for...

I think a “king cab” or extended cab Cybertruck could be a popular option. Basically the bed would extend half way into the back half of the cab. This would give you an 8’ bed and a bit of area behind the front seats to store tools and other junk. The wheelbase would remain the same and even...

Unfortunately, I am not as bullish on the availability of the 4680 compared to a year ago. Three months ago Tesla said they are 12-18 months away from volume production of the 4680. So, best case scenario is April 2022, worst case is July 2022. This may also be overly optimistic on Tesla’s...

If stainless steel is contaminated by mild steel it will rust. Even simply dragging a steel object across the surface of stainless steel could be enough to contaminate it. Banging an iron pan around in a stainless kitchen sink could lead to rust. If your kitchen knives are high quality...

And if they can shear the stainless on the Starship then a blank stamping press die would be no problem.

That is a good point, they are already cutting/stamping parts for the Starship. Since the shapes in the Starship are pretty basic I would imagine they are using some sort of CNC shear/brake/roll for these. The CNC cuts and contours the sheet all on one machine.

Heavy Gauge Press Here is a 4000 ton press, they say they can accommodate blanks up to 72” x 100” and the capacity is up to 5/8” steel plate (maybe 5/16” stainless?). There is a video on the page that’s shows it in action. A press this size could likely stamp all of the parts needed for the...

Also, hardening is a very general term. In regards to the Cybertruck I believe they are referring to cold rolled hardening. This is different than what most think of in regards to hardened steel. The term “hardened steel” almost always refers to tempered steel. Usually this involves...

I reference mild steel because that is what is most common, you see it everywhere. If a machine can process 1/2” mild steel then it can typically handle about 1/4” 304L stainless. To estimate capabilities you can use mild steel as a reference just halve it to estimate the machines capabilities...
