< Running Boards >
For running board and deck material, I obtained mesh patterned brass sheets from a club member. The thickness is 1.5mm. Of course I employed plain brass sheet for the rear half part of the running board which is covered with the side tank.
All of the running boards were finished by endmill. Beforehand a true steel angle was fixed onto the miller stage parallel to X-axis. It can lead each materials truly parallel to the milling stage.
Some of the running boards were bent with round brass bar. It is better ensure excess area before bending and cut it off after bending.
So as to ensure true scribing with a rule and a square, the material and the rule are clamped onto a flat table. You can use snap-off blade cutter as a scriber for brass sheet.
The valance around the running boards was made from 5*5mm brass square bar. They were bent by the Metal Bender. Due to hard extension and compression, the section of rounded part become trapezoid. So the outer surface should be trued up with a file.
The valance is fixed under the running board with brass countersunk screws. They are screwed from underneath and cut flush at the running board surface. It makes them almost invisible.
Running boards were connected each other with a brass angle which was spreaded with a vise and shaped with a round file to fit to round surface of the running board.
When I modified William from 1/16 scale to 1/12 scale, I extended the running board width. As a result, the front deck became too wide and looked unbalanced. Therefore I reduced the running board width only for front half part. The photo shows how the valance was arranged at this point.
The front deck between the frames is also made from the patterned sheet. The front pony truck's spring pin was protruded from the plate. So I made a dome from a brass round bar and covered the pin tip with it. Some Japanese locos have such a design.
The front and rear end of the running board was fixed onto the buffer beams.
After the running board was completed, the lubricator was re-mounted onto it. The slit for the swing arm was cut with a fret saw and finished with a thin file.
