Here is the new bending iron form I mentioned earlier. I originally designed this about a year ago, but lost interest in getting it made as I lost interest in violin making a little while back. I drew it out on paper, transfered it to AutoCad at my work, and was able to get my boss the CNC it for me. I had to cut off a square base where the CNC machined clamped on to it, tap the mounting holes for the little base plate, and do some filing and sanding.
It works fairly well. I set it to 3.5 and it was hot enough after 20mins but eventually got too hot, and 2 seems like it'll work better. I made three c-bouts and was hoping to be able to wrap them around the iron, but that didn't work as well as I hoped. The fatter end is too fat, but the tighter end was pretty much perfect for both the c-bout corners. The fatter end will probably be fine for the upper & lower bout corners. It also seems to be too flat across the sides, and I had to use the fat end to add more curve to the middle of my test c-bouts. I did, however, base the design off the Strobel model violin I built my first two from, and the c-bouts of the Amati Alard are much more curved (and nicer looking).



Here it is with the standard Ibex cast aluminum form:
