How to Make Seamless Corners

I did a video several years ago on how to do different corners, and am working on a new pattern / build prototype, so thought I'd do a much clearer version of making "seamless" corners - essentially building a piece of cookware or bakeware that does not require soldering to be water tight. Hope this is a little better visually that my last version of it! Let me know if you have any thoughts or questions!

Awesome, looking forward to seeing if you can perform a bread baking performance comparison to folded seam steel pans and a folded seam copper pan. This is super interesting!! I always lined my pans with a folded parchment liner during production baking to ease removal and quick batch turnaround. I also used steam injection (depending on oven) or a water tin within the oven for crust development, this may preserve the tin lined copper in some way indirectly through humidity in the baking process. Possibly pre-tin the copper interior prior to folding. Fantastic video, thanks for making this.

I definitely am going to play with this - I have aluminum baking pans and now this sample copper one, so I'll have to do that shortly and see what happens - I'm sure there will be some adjusting needed for baking times, etc. And yes, 100% you're right - if these were tin-lined, you'd want to tin in the flat before folding them. Thanks for the ideas and for watching!!

Really nice job. I did something similar with some reclaimed galvanized, but had my corners and safety edge folded to the inside. Then made a lid for it too. Keep up the great work!

[@housecopper]

Thank you so much for watching - super happy to hear you liked the video! Was your lid flat, did it have an interior band, or...?

[@telldpablo]

@@housecopper I honestly can’t remember. 😳 I’m going to have to go dig it out and look. 😁

[@ruairiallen3354]

looks awesome! I am going to try

[@housecopper]

You can do it! Yay!

[@mikesawaya3508]

Very interesting. I've been looking for a project I could make during demonstrations without having to solder

[@housecopper]

YAY! And they looked great!!

[@mikesawaya3508]

This seems like a good project to have a paper pattern with all the lines marked out. Glue it to the tin/copper sheet and then fast follow the lines on a creasing stake.

[@housecopper]

Yeah! Just like the tray designs at the convergence.

I've searched a lot for how to do this type of corner. What's the hand tool that you use at 6:38 to help fold the corner? What thicknesses of sheet do you work with?

[@housecopper]

Glad the video helps! :) The hand tool at 6:38 is called a sheet metal crimper. This video has 20oz copper, but I usually work in thinner gauges.

[@thetaonottaught]

Thank you!

I didn't have the tools to make a round copper pot so I made a tray to cook with instead. I'm a little worried that copper will come out of the corners even after I tin the pan.

[@housecopper]

Can you explain your worry a bit more? I don't know how copper would come out of the corners. Do you mean like the tin will not cover the corners?

[@rickwarner516]

What’s the gage of the metal?

[@housecopper]

This one is 16oz copper / 24gauge

Oh, so it's origami, but with copper. That's all you had to say.

[@housecopper]

Ha! I didn't even think the word origami when I was doing this, but yes, that's a great comparison! :)
