Tender Trucks - Radial Collar 2

A single bearing of only 7/8 diameter will not hold up very long with the weight of the water and the rider. We have had some bearing failures in the past with the same small brearing. I had two choices, one, use larger bearings. The journal boxes are only large enough to be bored to 1 inch. This didn't seem like a large enough increase. The second choice was to use two 7/8 diameter bearings, and make a radial bushing that would allow the bearings to flex in the journal boxes.

I made a radius tool holder extension to the compound that would give me a radius of about 4 inches. I rotated the tool by hand using the slightly loose compound as the pivet. Since the tool is mounted upside-down in the rear, the lathe must be run in reverse.
