Kozo K27 Lead Truck

The axle for the lead truck has been turned and is ready for the wheels. August 23, 2015.

Starting to work on the blanks for the lead and trailing truck wheels. The top three have just been contoured on the rear side. The bottom one is a completed blank with both side contoured. August 30, 2015.

The four blanks for the leading and trailing trucks have been completed and will need to have the tread and flange turned next. September 6, 2015.

The treads and flanges have been roughed out. Next up is tapering the treads and then shaping the flange. September 7, 2015.

The front two have been completely shaped and polished a bit. The back two will need some rounding of the flange, angling of the edge of the tread and then polishing. September 9, 2015.

All four have been contoured and polished. September 13, 2015.

Work has started on the upper portion of the lead truck bearing block. The block still needs some tapering on the top side for the centering device,  notching of the opposite side, a few holes and boring for the axle shaft once the lower bearing caps have been fitted. September 13, 2015.

The assembled lead truck bearing block and wheel set. Not the oiling holes on the top of the block. September 20, 2015.

This is the completed bistle post sleeve that is part of the lead truck centering assembly. September 26, 2015.

The main part of the bistle post has been machined and will slide up and down in the sleeve in the previous photograph. September 26, 2105.

This is the lead truck radius bar and my first silver soldered piece. The lower joint flowed better than the upper joint with a nice fillet. The upper joint has a slight puddle of solder that did not flow into the joint and will need a bit of cleanup. The next step will be to solder the attachment joint at the other end of the piece. October 3, 2015.

The bearing cap screws will be replaced with longer screws to attach the radius bar to the bearing block. Note that the radius bar will actually be flipped over to attach to the bearing block. October 3, 2015.

The cap for the bistle post has been turned. October 18, 2015.

The hanger which will fit inside the bistle post has been shaped and soldered. October 24, 2015.

The pivot and pin have been added to the radius bar at the far left. The top of the brass bearing box has been shaped for the roller of the centering device. October 24, 2015.

Today I worked on rollers, bushings and pins. The bushings fit inside the rollers and one roller will be used on the lead truck with the other two for the trailing truck. The long pin will fasten a roller to the bistle post and the short pin is for the pivot of the trailing truck. October 25, 2015.
