Well that's 2 impossible jobs done reassembling the motor
1/ Tying back the brushes to get them over the armature and then removing
the cord when in place.
2/ How to replace the 5 inch long steel screws , without any built-in
guides, passing between 2 powerful magnets. They go where the magnets want
them, not some midway path. Obviously made scratch marks before
disassempling but required the head of the screw held in molegrips until you
can feel it is in the tapped hole, screwdriver placed in head still in the
molegrips, pushing down, while you release the molegrips.
