I am the guy with the amazing wife who bought me fly tying gear for Christmas. I have a queston about my vise.

My brother has a Dyna King(I think), and when he rotates the fly, the hook never changes position. When I first put my vise together, I must of had something askew, because the hook moved drastically off the center axis as I rotated. After setting my vise up more like the picture, I have less movement off axis during rotation, but more then I have seen on my brothers vise. Do I have something set up wrong, or is my vise just different?

Thanks for the help.
