To clarify, this video is not about how to make spheres, which is done like this: kzitem.info/news/bejne/l3qsvXh5ppSBq6g I am demonstrating that welding 2 flat discs do not make a sphere as some people expect, and that by altering the edges the inflation can be controllable for making more useful objects.

He did, and he also mentioned me in his video (12:00). This video is focusing on (mostly) flat 2D circles inflating to 3D, made from just two sheets

@@ConnorHolland Why when multi sheet solutions work well? Maybe thin the centre area of a fairly thick and soft disc to match desired elongation. Eg the 'equator' weld and the 'poles' should stay constant while the area between must stretch up and out. So, update my "thin in the centre" to thin a ring between the outside and centre.

Ironically, I love the look of the first one, as a sort of hypothetical bean bag. I've seen some people do softbody/cloth deformations in blender and other physics simulations tools and then 3D printed the result; I think the one I like best is a simple sheet of cloth draped over a ball, but only the cloth is rendered, making a really cool illusion object. But recently someone did a small inflated pillow/beanbag style thing where they'd simulated a headphone case sitting on it to make a 'stand', and it got me thinking, you could hydroform a chair like those 90's inflatable vinyl ones, it'd have all the folds and wrinkles and aesthetic but be made of metal and much sturdier despite looking soft and plump.

I had one of those 90s chairs, I'm going to be making more pieces that resemble inflatables. Growing up I thought that inflatables were the coolest things ever, which probably explains why I like hydroforming so much

A tennis ball ... essentially made from 2 flat pieces shaped a little like a peanut shell, perpendicular to each other. Just an idea.

Great Experiments! In Your 3rd One as You were tapping the Pancake, the Sound it made hinted already at a faulty Weld or Weakness - so tap your Pieces and listen to the Sound :)

I really like the English wheel method to add a camber to the pieces! I always struggle with clamping the edges and heat distortion making the sheets separate.
@ConnorHolland

Yep the separation is annoying, wheeling also helps the piece inflate the right way, without unwanted folds forming

If you look up a paper called "wrapping sphere with flat paper" you'll see some great examples. Steel being more compliant than paper means you could probably use a simplified form. And you could almost certainly construct it out of only one or two sheets like you're doing here. Honestly though I love watching these experiments, there's so much to learn from them that "succeeding" would almost be a let down 😅

To go from flat to spherical, I recommend learning more about origami. You were closest with the last one, but the petals need to be inverted from how they are as the cavity expands - basically the opposite of the ravioli and likely with deeper inseams. I expect you'll likely need to preform creases or otherwise weaken the metal slightly to ensure creases development where you want them. A big part of the issue you face is scale. At this size, there are a lot of forces fighting each other, especially material thickness and work hardening. Ultimately, you won't ever make a perfect sphere this way, likely for similar reasons it's so hard putting the globe on a 2D map. You can get close, but there's a reason why industry makes massive metal bouys the explosive way it does.

I noticed an issue when you are tig welding the 2nd form shut. When welding, you do a beat, 1 inch, then turn the piece, so you always weld opposite corners. I don't know how much impact it will have on the end structure, but it's a thing :) Anyhow cool stuff man, love it!

put square teeth on the 2 circle edges, bend the teeth 90 degrees, then you can *mesh* the 2 circles and weld em

All these look like birthday metallized ballons. By looking at the edge patterns in different shapes of those ballons, we can learn a lot of the physics of shrinking at different edges "profiles" (and translate them to metalic shapes)

Yes, also the flexibility of thin foil helps to even out all of the creases, so maybe I should try getting thinner steel, or making my pieces larger
