S Gauge Rolling Road v3

This part is to setup S Gauge Steam Engine Chassis for operational testing. It will require two (2) of this kit to support any American Flyer Steam engine and most Diesel Engines. You assemble with no tools and the roller ball bearings must be purchased by you separately. There is a Base to hold the roller frames in place, but i have learned they are quite stable on a flat surface. The tender chassis can be attached or simply wired in to eh engine chassis. I use some DC Motors and can connect my bench DC power supply directly to the motor to test drives, axles, wheels and linkage. Then you can add the reverse device of choice and test that with track power. I also have an O Gauge version i will also post here and it used the same roller bearing.  The bearing used is the 625ZZ which is 5mm wide, 16mm in diameter and uses a 5mm shaft.  You find them on line from $.70 to $1.50. You will need 8 bearings to support an engine with 2 rolling road assemblies.
