Years ago I started converting a N Gauge 2-8-8-2 to a narrow gauge HOn30. But now I am starting a Hon3 layout and would like to re-gauge it to 3’:cry: . I have worked out everything but the actual re-gauging of the wheels. The model is a old Rivarossi and my concern is that the axles will need to be replaced. I could push out the old axel with the new but I don’t know what diameter stock to use. Also while I’m at it, I should convert it to DCC.
