Reply to "a source for wheel/axle sets? (Making lego trains for o gauge)"

You can just slide the bearings closer to the center of the axle, making it 3 wide between the wheels. There will be some lateral play in your axles, but after cutting the axles down and fitting new wheels I think it will be fine. Hmm, if you 3D print new wheels cutting the axle may not even be necessary, since you could just make the hole in the wheels a through hole. May make gauging more difficult though.
