Dirty commutators: Atlas Conductalube. One drop on the commutator while the
motor is running on a 9 volt battery does absolute wonders to the physical
appearance of the commutator, and very, very noticeably affect the motor
speed (20% increase in rpm) the second it hits. Mind you, no more than one
drop. Does not have any effect on plastics, brushes or wire insulation.
New experience: I had a motor from a Marklin F7 which was unusable due to a
"ring of fire" running around the commutator. No chemical, brush, or solvent
I had would touch it. But thanks to another member, I got the opportunity to
drop the motor into a 70% alcohol bath in an ultrasonic cleaner (MicroMart,
among others). After 5 minutes in the ultrasonic cleaner, that motor became
the best motor I own. It ran for hours and hours non-stop at last week's two
day GATS show here on the Z-Bend Track modules. Very impressed. I'm saving
my pennies for my own now.
