The journal bottoms for the trailing truck were printed and came out well as shown above.
The small amount of support was readily removed and the bottoms are ready to glue in place
The journal bottoms are shown along with the side frames.
A bottom view of the frame shows the remaining support strips on the bottom of the journal bottom covers.
After cleaning up the frames and tapping the screw holes the trailing truck frame is ready for assembly. By using screws the hold the two side frames together the truck can be disassembled in future if need be. The frames are held together with 2-56 screws one at front and another at the rear. The frame parts are tapped so nuts are not used. The large part at bottom center is not part of the truck, but is the pivot assembly that will later be assembled as part of the back frame. The truck pivot is also a 2-56 screw so the pivot assembly was also tapped. Tapping is done by hand and for the small size screws is very easy to do.
The fully assembled truck is shown above along with the pivot assembly that will be assembled into the back frame of the locomotive.
The temporarily assembled back frame of the locomotive was slid into the back of the main frame and the trailing truck pivot screw installed to hold the parts in their respective location.
A close up of the trailing truck pivot attachment is shown above. The truck rides quite close to the back frame. Other parts will be assembled on the back frame to provide truck spring and equalization coupling and truck centering.
