Put this little wire bender together for model airplane landing gear. It was made from stuff in the scrap box.
Really could use some finishing touches but then it would not be quick.
One bolt is used for the end rod and that has a small radius around the shaft to hold the wire while the arm is rotated on it. The wire is picked up by the radiused allen cap screw on the arm and then rotated until it has the desired bend against the radiused allen on the steel bar. Works fine for upto 5/32 music wire.
