Kozo K27 Trailing Truck
The frame for the trailing truck has
been roughed out and cleaned up some. This piece is about 8" x 5" and
made of 13 gauge steel. October 31, 2015.
Progress has been a little slow this
last month with other distractions but the trailing truck journal boxes
are starting to take shape. The boxes will be fitted with bronze
bushings and a cover and then bolted to the truck frame. November 29,
The two journal boxes have been
machined with mounting holes and an oil hole on top. Next will be the
bronze bushings and the journal covers. December 6, 2015.
The trailing truck journal box covers
are starting to take shape. The next step will be drilling the four
mounting holes to secure them. Then it is on to the journal brasses.

The journal boxes have been fitted to
the trailing truck frame. I found some hex head 4-40 screws to attach
the boxes to the frame. December 28, 2015.
The radius arm has been machined with
the centering pin pivot point silver soldered to the arm. The centering
pin is held in place be a 5/32 diameter rod with small e-clips on each
end. The arm is attached to the frame with 3-48 socket head cap screws.

The journal boxes have been tapped and
journal covers drilled for the four mounting screws. September 6, 2016.
The trailing truck pedestals are being
roughed out of a block of steel. The lower center web will be cut out
once all of the other machining has been completed to allow the
trailing truck journal to pass through. The upper web will have a
roller to ride on top of the trailing truck journal box. September 25,

The last parts to be completed on the
trailing truck are the yokes that will attach to the spring rigging.
Here is one of the yokes attached to a truck pedestal. Three more will
need to be completed since two are required on each side. December 31,
