< Platework 3 >
The spectacle plate should be closely fitted
to the boiler barrel. It is better confirmed
with a card board before cutting material.
Also top radius of the plate should be traced
from the roof. However, after all I did for
it, slight gap was remained.
I added a boiler band so as to hide the gap.
The left end of the band was fixed on the
main frame, while the right end was screwed
into the running board. The screw can be
adjusted to control band tension.
The front window glass was made from PMMA
clear sheet, sawn out and filed to the desired
profile. The window frames, sawn out from
a brass sheet, hold the glass from both sides.
I employed M1.4 micro screw for it.
Aluminum angles were added in the side tank,
so as to prevent water rocking.
Inner and bottom plates of the tank are assembled
with countersunk screws. The photo shows
transferring a screw hole from the bottom
plate to a brass angle.
Inner-left side plate has a step, so as to
clear the reach rod. Note brass square bars
were employed as spacers. These parts were
fixed with copper rivets and soft-soldered.
Manholes of the side tank were made from
brass round bar, and soft-soldered in the
top plates. I utilized high-temperature and
high-tension solder for it.
As reinforcement of the roof, brass band
plates were fixed with rivets behind the
roof.
Air vent pipes of the both side tanks were
made of partly threaded cupper tube elbow.
They were screwed into the spectacle plate
and locked with nuts. Top end of the elbow
should be higher than the top plate of the
side tank.
Connecting pipe of the side tank is made
from brass tube with rectangle brass flange.
The flange is silver-soldered, then trued
up in the lathe. Inner end of the tube is
covered with brass mesh filter.
Cab handrail is almost the same as smokebox
handrails. The rail was press fitted to upper
stanchion and loose fitted to lower stanchion.
Whole body was assembled with silicon sealing
glue. Inner side plates and cab inside were
painted and stoved before assembly, because
it is difficult to do afterward.
