Great history. I didn't try to bend the original (which may still be 'round here somewhere), but used a length of (probably) drill rod (O-1). I used a bench vise and a section of black iron pipe for the job. The handle (and all the others that I neurotically make for all my presses) makes the operations all so much more effortless. The length of the handle = the leverage (speed) of the ram. I've made three for the CoAx and for the RC. The ball ends are from MSC, the industrial materials supplier.
