I've gotten the hang of boil and pop, but I can't for the life of me make any progress reversing it. I'm working with the 90s Kenner Star Wars Power of the Force figures, which have a hard torso with holes and soft limbs with pegs. I don't have the tools to try cracking the torso. The only guide I've found that says anything about reassembly only said to cut a 'V' notch in the pegs, then boil the limb and force the peg back in. Well, I tried that with absolutely no success. It didn't come even close to working. What am I missing?
