A slip roller would make short work of this, but the radius is way too small for that, unless there's something out there that I missed.
No, this is not a wet environment. I was hoping to stay with corrosion free parts for longevity. Maybe I'll explore some 304 as well, but it's probably going to be only a little easier than the 316.
Now, the two halves idea. That may work, and might even work with my existing mandrel pliers. I cut my cones out of a sheet using a template made from solidworks, and it's very accurate.
Now you also have me thinking about the rubber mallet idea. If I have a male form of the proper bending radius, and use a rubber mallet that will conform to the form, then the resulting sheet should come out to the proper final curve. I'll Google this, but where does one find information on a bend radius required to get a desired radius?
Okay. I found a calculator, and am a little surprised by the results. My experience is that this material is springier than the calculations show. Assume a cone, 5mm on one end, and 10mm on the other, and only making a 90 degree bend:
final radius initial radius bend angle
5mm 4.7mm 96
10mm 8.8mm 101
