To answer your other questions, it is not difficult to remove the TPE sex doll from the skeleton. The bottom of the foot was most damaged because I needed to cut it open to remove standing foot metal, but for the rest of the leg, this was just a progressive cut along the seam. Once I cut the tape at the knee joint, peeled it off and cut the TPE from the drill bit stuck to the metal until it was completely separated, it was simple.
I would open the hips and tie the metal back with a metal zipper to keep her legs soft but still workable. I just sealed it up and used the video on YouTube-using heatgun and metal pieces .. feasible and sure. Thanks for the information you provided, I haven’t realized that there will be tape and TPE / metal bonding to make it so difficult.
However, if my supplier cannot fix the replacement body, I might try to see if it is possible to cut the TPE around the tape / metal without puncturing the surface. Even if it causes external damage, it is better than a completely loose leg. I think in this regard, even a complete amputation of the leg is better than my current situation. I have to make sure that no water comes in from the open stump, but at least I can pick up sex dolls again.
