I would agree with Steel510, I don't see how you could straighten connector rods to an acceptable level once there is a bend in it. The connector rods are a type of rigid pipe, similar to electrical EMT. I have done my fair share of EMT bending for electrical work and once you have a bend it is darn near impossible to bring it back to a completely straight pipe again using a bending tool. The pulley type tool shown is for straightening tubing, not for rigid pipe. You would need a ductile or malleable material to go through a pulley mechanism like this, otherwise it would take something like a hydraulic press to push the connector rods through the pulley mechanism. In the end, I still don't think it would straighten with this because the material is too rigid. Like in EMT bending you would need to pull the rod in the opposite direction to counteract a bend, so just putting it through pulleys won't straighten a bend in rigid material (IMHO).
