bender looks like it would work.

So, I assume I also need a bunch of dies for the sizes and angles I want to
bend.

I have these questions:

- How close does the tubing diameter have to be to what the die was designed
for?
- Does the die radius exactly determine the bend radius?
- Can the angle of bend be anything up to the angle the die was designed
for?

I have a 4 axis cnc milling machine, so what I may do is order one die set
and use this as a guide to making others.
