I just purchased a Telecaster that has a Hipshot B bender and drop d combo mounted on it. BUT, it is missing the rod that controls the b bender. I looked on the Hipshot site and it is going to cost $42 shipped. I believe I can make one quite a bit cheaper. I believe it is 5/16 hexagon rod, but I do not know what the total length is that I need to order. Or at what length do I need to bend for the angles. What metal to use? Brass, Aluminum, or Stainless? Any help would be greatly appreciated.
