3-14.

 Place the boiler on the chassis. Screw an 

M3-5 phillips-head screw (31) through the deck and 
into the rear mounting stud from underneath. Do 
not tighten it too much yet.

Fasten the smokebox to the saddle with two M2 
x 4 phillips-head screws (40) through the saddle 
plate, as per the drawing. This is most easily ac-
complished by inserting your screwdriver through 
the smokestack hole for access to the screws. The 
screws can be put in position with needle-nose pli-
ers through the smokebox door. 

Referring to the drawing, carefully bend the short 
leg of the steam pipe until it will smoothly mate with 
the thread on the throttle. The two must be well 

aligned for a steam-tight fit. Secure the union nut 

to the throttle.

3-15.

 Place the smokestack washer (53) on the 

smokestack  nut  (52)  with  the  flat  side  bearing 

against the nut. Open the smokebox door, insert the 
nut and washer from inside, making sure the cur-
vature of the washer conforms to the curve of the 
smokebox, and screw the smokestack (54) partway 
on. Tighten the nut, making sure the curvature of 
the bottom of the stack conforms to the smokebox. 
Secure the nut tightly with pliers. 

Drop the exhaust pipe (55) down the stack and 

screw it into the valve-block. It need only be finger 

tight.

3-16.

 Slip the burner (25) into the flue opening in 

the back of the boiler and secure it with an M2 x 4 
screw (3). Secure the gas tank (28) to the deck with 
one cap nut (29). Slide the jet (26) into the back of 
the burner. Carefully and gently bend the copper 
gas line until the threaded part of the gas valve lines 
up well with the end of the gas line (photo 11). Tight-
en the union nut to the gas valve.

At this point you should have a working locomotive. 
Ruby was designed so that the cosmetic compo-

nents (cab and tanks) could be easily modified. The 

boiler and chassis comprise the working portion of 
the engine. If you’d like, you can try it under steam 
now, or you can wait until the tanks, cab and domes 
have been applied. 
Refer to Sheet 5

5-1.

 Take the steam dome base (66) and place it 

over the safety valve. The steam dome (65) screws 
to the safety-valve bushing, securing the base. The 

sand dome (64) merely slips over the filler plug and 

is held in place by gravity. Be sure to the remove it 
before turning the engine upside down.

5-2.

 Lay the side tank support bars (61) across the 

brackets, beneath the boiler. Take the right-hand 
tank (62) and place it on the bars. Holding every-
thing in place, carefully turn the engine over and 
fasten the tank with two M3 x 5 screws (31). Repeat 
with the left tank (67). 

5-3.

 Screw the cab sides (69, 71) to the cab front 

as per the drawing, with M2 x 3 screws (72). Then 
attach the roof with four M1.6 x 4 screws (73). Rec-

ommend  attaching  the  front  two  screws  first  and 

then the rear two screws. The cab should slide eas-

ily over the boiler. If it does not, file the inner edges 

of the cutout around the boiler until it does. 

That completes the Ruby kit. Now go outside and 
enjoy many years of steaming.
