When i was chilling with Uncle Don he explained the process, its like figure sculpting, Cut and Paste but on a whole more advanced level, CR and Don, the Great J Boy and DC when making there figures save every piece of figure parts they have. once they get the figure set and mounted they use other parts added to the shoulders, legs biceps hands and sculpt them to the look the want with a dremmel. I remember Don showed me some Big Belly lineman that were off the meter! its skill guys practiced and mastered skill.

Stay Blessed
