I drilled out the center of 5/16-18 stainless steel button head socket screws to match the dia of the tungsten rod ( 1/8"), then I a vise to slightly compress the bolt to close in the hole a tad, pressed the tungsten rod into the drilled bolt ( screw), ground of the excess length of rod to make them all match. I placed the bolt into the holes on the disc and installed the nuts, being that the bolt was slightly eliptical, the nuts went on with some tightness ( almost self locking) , and balanced the disc... a bit heavier than just the tungsten rod but very easy to change out....

That sounds like a good idea, especially since it's such a simple solution!
