Thanks, Jeff. This sounds actually do-able!
I have had no reason to remove the shell on my MTH PS3 scale-wheel engine (but I should to do something about the red marker lights which look cool but are always on when the rest of the lights are on). I hope this is easy, too. I have found Atlas has too many screws, that seem to be in inaccessible places, to get their danged shells off. The first time I did an Atlas dis-assembly I think I unscrewed 1,000 screws. Of course, only 6 held the shell on.
