Just a word of caution. You said you want to bend 2-56 material. This is a poor practice as the threadied rod (which I assume you are using) is very weak after being bent. If you are talking about bending piano wire of that general diameter, you are okay. I also like the L bends much better than the Z bends when used with the proper atachments (those little plastic clevis like things that lock the Lbend onto the servo arms). They have less slop, are easier to install and easier to make.
