Resistance Wheelsets on Gary Hoover’s Santa Fe Model Railroad

The smaller resistor has the advantage of being close to impossible to see on the axle. On most boxcars there are plastic axles, so modelers can use either type of resistor. Axles that are metal should use the common type of resistor, because there will be less trouble of shorting out between the wheels.

Before he superglues the resistor onto the axle, Gary needs to make sure that the inside of the wheels are conductive. This is because many times, the manufacturers place paint on the inside of the wheel. He uses a file to remove this paint for a better electrical bond between the lead on the resistor and the wheel itself. He does the same with the surface tread on the wheel.

The ends of the resistor are bent up slightly for better area to apply the conductive paint. He uses Nickel Print by MG Chemicals applied on the areas where he removed paint with a toothpick. When the paint dries, it creates a great conductive bond between the lead of the resistor and the wheel itself. Allen Keller goes on to ask Gary about the subtle weathering on his layout. He uses weathering powders for basic weathering and dry brushing with a dull silver paint on aspects that stick out, such as rivets on a tender.
