I have made a bunch of fairings with those linear dies since the 1990's, but I got a more complicated set to make recently, and wanted to try using more power, get fewer marks and see if that took less time to produce a more complicated shape.

I discovered that I could use a "radius-forming" bottom die with an upper contoured high durometer die for best results. Then I made a curved radius-forming lower die and used the same upper die for more aggressive shaped - and that worked nicely. It takes some serious pounding, but it is really no problem, and I have lots of power to spare before the metal fails, so it is a very comfortable method. I anneal once, only ... and then trim off the edge cracks once before I get my shape.
- and I can also make rocker panels of varying radii, in long lengths. I even radius-formed some .063 bronze, with no marking, just to see .... nice stuff. Have to get some images of that....
