I've done some work on my new Warlord Titan. The changes were both structural reinforcements and cosmetic. I've decided to put pictures online for anyone else with one of these so they might get some ideas for their own. The above picture shows the underside of a foot. The dots are 0.75" brass nails (called extrusion pins). I've drilled up into the ankle pieces. If I didn't do that a sideways bump could take the feet right off.
Above are the legs. You can see two more brass nails on the side of the ankle and four on the knee. I've added two pieces of square plastic tube to the backs of the trim pieces on both the thigh and calf. The piece on the top of the calf portion is a rod. Adding those pieces immediately took the look of the legs from kind of bland to very cool. I would highly suggest everyone to do that.
I used the back of one of the Bastion's weapon mounts as a control panel. You can also see a lot more reinforcing brass nails. Many of these were required to prevent the pieces from coming apart. They flexed and cracked quite a few times before I did this.
