Can you tell me how you made the joints? I'm planning to do the exact same thing with my War Machine that is the same exact mold. Good idea, to take out the sound chip as well. This thing looks awesome!

the stomach joint I cut him in half and then I had to make a plate in the upper half so that I could attach a ball socket from another figure inside to the lower half. I also used the shoulders and hips from a dc universe figure to make the shoulders and hips move on WM. its a lot of grinding and make it so the parts fit together just right. good luck and feel free to ask questions if you get stuck.

Nice improvements! He looks much better! I don't get why they don't just add the joints!

This looks cool! I love the LED work and wish I could do it! -Fitz
