AtlasO 36” freight car wheels on Williams axles. I used a layer of heat shrink tubing to make the wheels a press fit. I used my thumb/finger press. The heat shrink idea was from Rick Bacon.
I tried the heat shrink tubing on the geared axle. I could not get it to hold. I am using the K-Line passenger car replacement 36” dia. axles for the unpowered axle. I am trying to adapt the K-Line wheels to the geared axle from the locomotive. The axles are .0935 on the majority but are turned down and knurled on the ends to 0.090 where the wheels mount. The K-Line wheels were a press fit on .0935”. I plan to make some bushings for the wheels.
On either side of the motor block I am using a .015” thick washer. There is about 0.032”play on each side without the washer. But that is with using wheelsets of the older O scale .175” standard with thicker flanges and 1.125 back to back dimension.
