Reply to "Needle point wheel sets on old flyer"

I did the same type of test with the KC trucks with and without the brass eyelets.  I used two examples of the same car.  One with the eyelets and one without.  I did not push the cars, but set up two tracks on a slope.  The car with the bushings rolled farther and smoother than the one without.  I didn't do any of the math required to calcuate the force that was applied, but there was a significant difference.  think I'll repeat the experiment and calculate force applied and distance traveled to get a more precise result.  In my opinion, it's definately worth the buck or so per car to retrofit.
