Ok, I am trying to swap a MT SL-1 into a Scaley Mini. Unfortunately, the original motor and the MT SL-1 have different length shafts. And the MT SL-1 shaft is too short. (Go ahead, laugh.) I have tried to solder a brass tube to the armature shaft, but that is a no go. (Why? I don't know). I assume that I did not get the armature shaft hot enough to solder to. Of course, I did not want to ruin the motor... Any hints?
