Hello again, with this post i just want to contribute to the mono mod statistics. I was unable to remove the cover glass from my D5100 sensor with a soldering ion. So i thought more temperature might help to create a bigger heat gradient. I ordered a pen torch and for about 1/3 around the frame the increased heat of the torch seemed to loosen the epoxy resin. That`s almost the end of the story. In the end i tried for over 3 hours to get the cover glass off. I heated one corner a bit longer (maybe 3s) and the glass cracked... I knew i wouldn`t get of the glass in one piece anymore so i taped it up and started chimping with a scalpel. Long story short, i broke the glass out with an M1 flat screw and i seemed to have damaged one of the bonding wires (maybe this happened at the epoxy sealing step afterwards... i can`t tell). I carried on to polish the sensor just to get a feel for it. This procedure seemed more or less to have worked (at least according to comparison with Herras documentary pictures). I put the camera together again and everything works where the sensor is not involved. So just for statistic reasons. The current score is: technology 1 : 0 me. best regards Matthias
