I have what I assume is an early MB - the blue Speedo pelvis is made of a flexible rubbery material rather than a hard plastic like the flesh colored parts. The waist "belt" has vertical splits in two spots. I think that the combination of the flexible material and the splits have allowed the rounded bottom of the torso piece to settle lower into the pelvis than it should, which has caused the tension of the leg rubber bands to decrease to where the hip joints no longer hold position. If I pull the torso away from the pelvis to make the proper amount of rounded bottom of the torso show above the belt, hip joint tension goes back to a useful level.
I don't think pulling the bands tighter is the right solution, because that just encourages the pelvis to spread more. At this point I think some sort of rigid insert that would sit around the rubber bands between the pelvis and the bottom of the torso would be best - maybe two "C" shapes that could be inserted from the waist without disassembling the torso, or a single "3" shape? They would have to be broader than the opening in the torso bottom by narrow enough to sit in the bottom cup of the pelvis. I have some moldable kydex around, as well as other materials.
Has anyone dealt with this before? Am I on the right track?
