Hi All,
I was wondering whether there are any exeperts or "seasoned amaturers" out
there who could give me some guidance.
I have a black 12v motor and due to the length of time that it has run, the
4 electical connectors (the spring loaded ones) on the bottom are wearing
away, creating contact problems with the middle rail.
Firstly, how easily are these motors to open up and secondly, I am sure Lego
will not be supporting spares for this motor, but I have access to a lathe
so could knock some more up, but what are they made of - looks like copper
but I am not sure .
Any thoughts or suggestions would be greatly appreciated.
Cheers
Joff

| Jonathan, The copper-like material that you refer to is called "phospher bronze". It is used for applications like motor brushes and machines well. Good luck with you're replacement plans. -BMW (...) (24 years ago, 16-Mar-01, to lugnet.trains)
