More info. The good people at Digitrax (who are going to send me a new decoder out of the goodness of their hearts - their warranty even covers the buyer's stupidity) say that the buzzing decoder is a sign that I did not fully isolate the motor from the track pickups. I think it's more likely that everything was good until the motor and flywheel started moving from its intial setting and I had some unwanted contact between chassis and the motor brush contacts. Regardless, lots of things to evaluate before I get a replacement decoder.
I was up at Niagara Falls late last week spending some vacation time with my wife and had a few hours there in the hotel room between 2 and 4 AM each day (my back was bothering me and I couldn't seem to get back to sleep easily up there) to think about ways to improve the motor mounting and improve the isolation.
When I got back today, I drilled out four holes to interface with the 4 motor mount holes in the can motor and ran some screws in there through the brass plate supporting the motor. It was a lot sturdier than the wrapped electrical tape option I was using previously.
There are still some tight tolerances between the flywheels and the chassis deck, and even if they won't cause an electrical issue, the potential for friction has me thinking that I should make some adjustments. I'll be looking into the best way to make those changes in the coming days.
