Is their a center hole in it or not? What I am asking is that how do you put all the pieces together. I have seen images in which you can see one long screw that goes all the way through all the pieces. I think that the Graflex clamp clamps onto the end piece and the grenade thing on the other side, tension from the long screw gives it the tension to remain straight. Is that true?
I basically answered your question when I said there are two threaded rods running through it, but yes, EVERY part has a hole (of one diameter or another) in the center, and most folks assemble their hilts with threaded rods. It just depends on the parts you've got, but there are many ways to go about it.
