Hi All, I know I’ve learned a practical way to do this at some point, but have since forgotten it and am hoping someone out there knows. I’m also hoping I can describe this well enough for anyone to understand. I’m making a mount composed partly of a ring that needs to go around a conical stone sculpture base. Basically, a very short cone. I’d like to make it out of flat stock for good contact and best appearance. There is a method where the flat stock is bent in its flat dimension into a curve, and then the piece is rolled in its thin dimension to make the ring. If done correctly, the walls of the ring tilt in at the angle you want, and the ring itself is flat. Does anyone have a method for how much curve you put into the flat stock so that it’s appropriately tapered when you finish? I’ve found sheet metal layouts for making cones, but it seems that I recall a fairly straightforward way to do this.

Hi Jamie. For me it would go like this. Wrap the cone in paper and draw the mount ring shape out on it. Unwrap and lay this out as your paper pattern. I would use my Duo-mite bender. There is a configuration they have drawn out in the instructions to bend flat stock on its edge. I would anneal the brass and bend it to match the paper pattern. Anneal it again and hand wrap it around a homemade wood cone pattern. That should get you there. George

Hi George, That sounds good. Sadly, the information I neglected to give was that I don’t have the object in my possession. I had to measure a whole show at its current venue to prepare mounts for its next exhibit here in Seattle. I made templates so that I know circumference and the slope of the sides of the base, but I cannot empirically test it out. I went ahead and rolled a piece of stock edgewise, and then rolled the ring, and now have a reasonable example that is just sloped a bit more than desired. I’m hoping the next one will come out a bit closer. I figured I’d ask the group as I remember somebody showing me a way to do this in a way that made sense at the time. Thanks! Jamie

Step 1, anneal brass.
Step 2 bend it the hard way (edge bend) see photo
Step 3 bend it the easy way, see photo
Here is a photo of an African mask that I made using this technique:

Hi Philip, The “hard way” then "easy way" bends are understood. What I’m after is a way of determining the “hard way” arc so that when it’s rolled to a ring of the desired diameter, the slope is as desired. The first one I made is pretty good, but the next one is going to need to have a bit more precise slope to do its job as well as I’d like. I’m playing with some other theories and I’ll let you all know how it comes out. Not having the object at hand makes it all a bit of a challenge, but isn’t that why we do this funny little craft. One thing that helps is that I’ve made some additional attachments for my Duo-Mite Bender, and now have a three wheel roller. The handle is from my milling machine. I thought you’d like to see it.
