Bogie Wheel retread

At my last event two of the bogie wheels which I just installed peeled off after only a few miles.  This was really frustrating and I wanted to see if there was an alternative to using 65 year old wheels.  Despite the fact that there might be a good supply of NOS wheels available they are still 65 years old and the rubber has aged.  I found a local company which will retread the old metal core with new urethane.  They will remove the old rubber, media blast metal and install the new urethane.  The urethane has the same durometer rating as the rubber from a rubber bogie wheel.  This new bogie wheel has a modern chemical bond between the metal and urethane versus the mechanic bond which was used 65 years ago for the originals.  The first sample has a sudden transition from the side to the rolling surface.  I am going to try and get a more rounded transition for the future ones.

 

The old rubber has been removed.

The rust on the edge extends about 1 inch from the outside towards the inside. This is the main reason for the rubber to peel off, the bond has been weakened.

Another bogie has been removed from a hub.

The new urethane wheel is on the left and a rubber one is on the right.
