You need a heat gun. You will have to move that part away from the foot. It is not easy. Keep the heat gun moving at all times. Heat inside and out mostly outside. The Carbon has to get pretty damn hot. I use a C-Clamp, a rock and a wash cloth folded as many times a possible. Put the wash cloth on the outside, put the rock on the inside and use the 4" c-clamp to smash the rock into the carbon, and into the wash cloth. Let cool. Repeat if necessary.....
