I had no idea such things existed! This item doesn't come with a big enough ID, but I'll look around. Thanks!

I was just pricing one at Harbor Freight....$800. If I had any other use for it, I might go for it. I understand they can be pretty dangerous, though, if you don't know what you're doing. And I don't. :-)

No, I've spent hours looking. My purpose is non-standard--I'm going to use them for cookies and people don't use molds for cookies. That's why I wanted them about 1/4"H. I'm worried that taller ones will make them brown funny, but I won't know until I try. I did find some that were 2.5Dx 0.75H" high on a restaurant supply site. For 3.0" D, the height jumps to 1.0".

2ft for $38!

Hopefully I can find some SS ones, then. I'll have to bake them first to make sure there aren't other nasty substances hidden on them.

Fantastic! I'll order a few of these. They seem to be thicker than I wanted, but they still might work fine; I won't know until I try them. Thanks for the idea.

Could have attracted a very different audience!

Oh, yes, very, very close! I see something about a nylon insert locknut. That sounds like a problem in an oven. Is that just one particular design or are all brands likely to have that?

>Seems like there should be some biscuit or cookie cutters out there that will work.

They come in sets, so it's an expensive way to go. I'd need a couple of dozen. Biscuit cutters are also probably too deep, being 3/4+. I don't know yet how important the height is; there needs to be some airflow over the baking item so it will dry and brown.

>A pipe cutter can do it but they're expensive.

Yeah, the cheap ones can't handle the diameter and the ones that can seem to get pretty pricey.

What tool would you use?

I thought about something like this, but didn't know what to look for. Shim stock? Half of life is knowing what to Google on.

And I wasn't sure how to close the ring. I do have a MIG welder, but never got around to assembling it.

That's where I got the ones that I want to slice up. :-)

I was afraid of annoying them with such a little thing. Small $ customers can be so aggravating...

OK, I'll order one and experiment with it. Can't have too many tools. Thanks for the suggestion.

precision isn't that important...I'd be OK with 1/8" variation. I am considering a pipe cutter...wasn't sure how well it would with these rather flimsy tubes.

Yep, I was thinking along those lines. Would hate to have to cut parchment every time, though. I do have some silicone bands that are too thin to hold a round shape, but might be able to line the clamps with those.

I'm hoping the dough is too stiff to go through the perforations. Will just have to try it and see.

Thanks for kicking around the ideas.

The ID is 2.5", so a dowel would be too small. I left out the ID, because I didn't think relevant, but suddenly it is. :-)

But, yeah, I was trying to think of some way to make it effectively longer. Didn't think of something on the inside. Might be able to insert a 2x4 or something.

(McMaster-Carr does have a SS tube with thin walls I could buy that might work, but 1 ft length is about $100. And I might be only able to use half of it, because of clamping length requirements.)

Doesn't have to be SS, but wanted to make sure the substance is food safe. I'm making some baking molds. I've ordered some hose clamps that might work, but those have perforations in the metal, which might make removing the items after baking difficult.

Searching on "rings" produces a lot of hits that are actual rings, cylindrical metal formed into a ring, which probably wouldn't work, since, again, the material would be hard to remove after baking. (And wouldn't produce a flat edge.)
