I did try to remove the stator with a screwdriver but the only thing I managed was to leave dents on the bearings. Perhaps in a different motor it would be easier. I found a thinner wire from a little tranformer (guessing about 0.3mm) and tried it for the trigger coils. I got about 50 turns on each but again I couldn't get the transistor to open. I'm guessing that unless enough induced current passes through the base of the transistor this is doomed to fail. Am I wrong about that? I'm sure I saw someone who replaced the original wires with thicker ones like I did but can't remember where I saw that. I would use the original wires but they are just too thin for my clumsy fingers. If someome has managed this successfully your input would be appreciated.
