Other than the fairly expensive chamfering or edge rounding mills (more than double what I paid for my whole set of 6 regular mills), is there an alternative? Granted, with the amount of use they'd get, they would probably last me nearly forever. But hobby funds are tight, and I need a less expensive way.
Relatively long straight edges I can do on the mill with the proper setup. Heck, if I want to spend the time, I can use a file. How about on a radius? Can I cut a piece of drill rod and harden it to produce a decent edge? If so, can anyone post some pictures or C-o-C sketches for me?
