Take a look at the photos. I have several Lionel freight cars of various types that the needle axle ends are wearing through the plastic trucks, so that the cars will no longer roll without dragging and rubbing wheels on base of the car or frame etc. These particular cars shown are the Thomas freight wagons. I tried gluing on washers that I had on hand this slowed it down but then they started wearing to the side. Are there any more durable needle axle bearings available that could be glued into the holes?
Other then that was wondering about drilling small chunks of metal and gluing them in the holes or ??? and other ideas? thanks
