First of all thanks to those that had given me advice,tips, and answers. Now here I am agian seeking for help. I am customizing hayato from marvel vs capcom. Anyways I used marvel legends bullseye as a base body. After doing all the sculpting, all I needed is to paint. But I broke his arm, I broke the peg(is that what it's called?) that connect between the shoulder joint and bicep/arm. Now the peg is stuck inside the arm. Now the question is, how can I fix it? How can I remove that stuck peg inside? Or can I replace the whole arm including the shoulder ballpoint without cranking the torso? Will heat and pop work on removing the shoulder ball joint?
