Been out of town, and to answer some questions:
I am using a modified grip hanger and have made a leather holster for the vacuum tube. The holster provides the much need additional support with the heavy weight; it has 2 belt loops and a strap, which I tighten around the shaft of my penis. The suction from the tube and this additional strap allows me to hang heavy weights. Unfortunately not without occasional problems which I am experiencing now (skin blisters from all the pressure) when they heal I will demonstrate how this device works.
