Bettendorf Truck

This is my design for a heavy duty Bettendorf truck. It is designed to use standard R8 ball bearings. The bolster slot in the side frame and the spring support plates are designed so that the bolster is free to twist and move up and down with out spring force being applied to the bolster in a no load condition.	Patterns and resulting castings. Spring support plates and dimple die used to form dimples in the spring support plates.
Height gauge setup to layout out vertical scribe lines.	Height gauge layout of horizontal positions.
Drilling axle-bearing holes.	Boring bearing holes.
