  1. Lets talk 4680

    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...
  2. Lets talk 4680

    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...
  3. Regular cab cybertruck

    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...
  4. Regular cab cybertruck

    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...
  5. Lets talk 4680

    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...
  6. Actual finish of stainless steel exoskeleton?

    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.
  8. I Think Cybertruck Manufacturing Run Will be Short Lived

    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...
  12. I Think Cybertruck Manufacturing Run Will be Short Lived

    I can’t image it being a problem. The Cybertruck’s 3mm panels are around 11 ga, this is not a difficult job for a heavy-gauge blanking press. I see pressed parts made from 1/2” mild steel regularly. The stainless is obviously harder but these presses can usually do 1/4” stainless with no...

    I do like water jet, it is a cleaner cut than lasers. Lasers cut parts aren’t perfect, they usually have a bit of dross/slag left over that typically needs to be sanded or grinded off. Only problem with water jet is they are even slower than lasers most of the time. Plasma would likely be the...
  14. I Think Cybertruck Manufacturing Run Will be Short Lived

    The tube on CNC lasers are considered a consumable part. They only last so long like a light bulb. And they’re not cheap. Also, CNC lasers take up a LOT of space. The table would likely need to be around 8’x15’ to cut the parts for the Cybertruck, maybe bigger. And they would need dozens...
  15. Chassis Materials (Stainless or traditional steel)?

    I can’t imagine Tesla using regular steel for any part of the Cybertruck’s frame. One of the cost savings of using stainless is the ability for the Cybertruck to bypass the paint shop on the production line. All traditional steel (and aluminum) cars are completely dipped in primer after all of...

    Good idea!
  17. Exoskelton fake news?

    The specs of the tri-motor are similar to my 2012 2500HD so I was expecting something comparable. HD pickups have jumped up a lot recently with their specs but realistically, the capabilities are still close to my 2012. I agree, aluminum is stronger than mild steel pound for pound. But...

    I am just saying the outer "silhouette" can be stamped using a cutting die, no forming or shaping would be needed. The general shape of the flat panel can be stamped out of the sheet instead of being laser cut. This would be much faster and economical compared to the laser.
  19. Exoskelton fake news?

    I am very confident in the Tesla engineers and am sure that the Cybertruck will accomplish exactly what they want it to. I certainly hope they wouldn’t take advice from me. My only concern is that it seems they are not designing the Cybertruck for my intended purpose. I realize I’m being...

    My Model 3 an Model Y have the same plastic on the bottom for aerodynamics. This is not structural, it is just for improving efficiency.
