To make my Sentry I used a Hasbro Doc Samson with Toybiz original Sentry belt and cape. I sanded the joints to avoid paint rub, I also sanded the bumps on his boots and belt away, then painted the figure with Citadel paints from Games Workshop. I then superglued the cape and belt to the figure, the original belt does not completely fit all the way around, but that doesn't matter as you can't really see it from side angles, as the cape covers his back. This is the first custom figure that I've made.
