Thank you for all that I'm looking into this whole business again. Several reasons, one of which is I think my 450D debayered sensor is now dead having sustained a broken gold wire in storage I am short of 450D parts but have plenty of 1100Ds. Several bodies less sensors, one with cold finger and one I've recently bought as not working but I believe the problem simply to be a broken battery connector - I haven't had it apart yet. So I'm looking again at using an 1100D for my mono DSLR experiments. A big advantage over the 450D is the more recent image processor with a maximum ISO of 6400 rather than 1600 which is very useful for DSO finding and setting up. We now have a seemingly useable method of removing the cover glass and you have found a satisfactory epoxy resin which makes actual debayering far less risky. I used the polishing method before but by hand which was very tedious but now there's the epoxy solution I would be happy to use my Dremel look-alike with polishing mop. I have a dead 1100D sensor with broken cover glass and many broken wires on which I can practice CFA removal. Regarding killing the sensor while debayering, yes, the short edges (without wires) ARE delicate and will cause failure if touched. This was discussed much earlier on in this very long thread.
