I like how you put that banana into the donut.

[@NathanNostaw]

Nice work, Fun shapes. It's interesting how the metal moves on the weld edges in relation to the flats. I can see a future pea pod based on the banana shape.

[@interstellarsurfer]

Awesome demo. 👍

[@wickedprotos1937]

Very inspiring!!!! I will try this when I can find time and get better at tig!

[@toddboucher6068]

I like your videos.I did some safety plate stacks a couple years back. Also some crosses that I thought turned out cool? Wish I had a tig welder? I’ll try to figure out some pics of if you are interested? The safety plate doesn’t seem to wrinkle in the odd corners? Thought you’d like, thanks

[@Scodiddly]

Cool backwards intro!

[@jackholf7502]

Banana split made me lol

[@JohnJones-oy3md]

Niiiiiiiiiiiiiiiiiiiiiiiice!

[@MikeOrkid]

Kind of curious how the "egg" sounds as an instrument.

[@ConnorHolland]

There's no vibration when hit, so it's like a solid block. However the donut was very resonant while it was flat, like a gong/bell hybrid

[@MikeOrkid]

@@ConnorHolland Awesome. I'd love to see a "musical" video sometime. Making differ toned "instruments"

[@ConnorHolland]

@@MikeOrkid That's a possibility, I've also made an inflated steel baton that changes pitch depending on the air pressure inside

[@TheAussiePirate]

👍🏻

[@gurdeepsinghkapoor7243]

Brilliant .....would like to buy some of these designs, pls share if there is any link for purchasing....Thank you

[@ConnorHolland]

Thank you, here is my website: www.connorholland.com/ You can purchase these pieces or request a new design by emailing me.

Hey i had a question how much bar did you used ?

[@ConnorHolland]

I'm not sure, but my small pressure washer's maximum is 90 Bar, and the workpieces rupture before reaching that

[@sangramprusty5896]

Can you make gyrocopter rotor blade on this method?

[@ConnorHolland]

Perhaps if you used a mold to get the correct aerofoil shape, but there will better materials and methods than this one

[@oneproudbrowncoat]

Have you ever tried limiting the expansion to increase it radially? As in, suppose you wanted a shape with two parallel planes and convex sides?

[@ConnorHolland]

Not yet, but it is possible to sandwich the piece between thick steel plates to create flat surfaces

[@oneproudbrowncoat]

@@ConnorHolland I'd have thought so.

[@ConnorHolland]

@@oneproudbrowncoat I assume that's how Oskar Zieta produces inflated steel mirrors with flat faces

[@oneproudbrowncoat]

@@ConnorHolland I can't say as I've heard of him, but I reckon you're right.

[@oneproudbrowncoat]

@@ConnorHolland Speaking of which, Mr. Holland, have you tried this method on aluminum at all?

[@4nimal_Den]

What do you do with all of these after the video?

[@ConnorHolland]

I have an idea planned for the egg, but mostly I keep them as samples to show how different shapes inflate, which helps when designing new products

[@alisherqodirov8857]

great can I ask a question?. what brand of stainless steel? and thickness?

[@ConnorHolland]

@@alisherqodirov8857 I used 1mm thick mild steel

Sideways bottle rocket banana there.
