@Tom Stoltz posted:Well Folks, I can now report that the Tichy nylon truck bearings (#3059) mounted in a 4 mm eyelet, is the answer for rollability. I used a link coupler truck which I drilled out for the eyelet, the eyelet needs to be reamed with a #43 drill so the Tichy bearing fits. All of this narrows the space between the sideframes so a SHS pointy axle wheelset fits perfectly. And it rolls like a SHS truck. Pointy axle wheelsets are still available from Am Models.
If you are interested in a slight improvement using SHS wheelsets without the bearing, 5 mm eyelets work.

I realized I didn’t post any pictures. Some more details: I use 5mm eyelets in knuckle trucks and 4mm in link truck. I no longer ream the eyelet with a #43 drill bit and still manage to seat the Tichy bearings. I use a CA glue to secure the eyelets in thee trucks. The difference in rollability between just using a brass eyelet and an eyelet with the bearing added is like day and night. With the nylon bearings added, the cars roll like new SHS cars.
A note about the knuckle truck car; I converted one end to a link coupler which you can see in the picture.
