9. 

Drill out 2.1mm the buffer bodies to take 

the cast head/shank. I hold the drill bit in a pin 
vice (chuck) and grip the buffer body between 
finger and thumb. Drill through the body from 
each end so that the hole breaks through in 
the middle. Use a little spot of spit on the end 
of the drill (some more technical people have a 
block of furniture polisher’s bees wax that they 
smear on the drill end). This will prevent the 
drill wandering in the white metal and breaking 
through the side of the buffer (a little 
lubrication on the drill will make drilling holes in 
any white metal casting more accurate). Then fit the shanks through the buffer body, snip off some 
of the narrow end of the shank to leave just over 1mm from the step and solder a retaining collar 
onto the shank.  

 

  Close up the coupling links by holding the curved end in the 
jaws of a pair of round-nosed pliers in one hand and squeeze 
the flat parts of the link parallel with long-nosed pliers held in 
the other hand. Once you have six even-shaped closed links, 
you can open each one slightly and thread three together.

BRAKEGEAR 

8.  Emboss the two bolt heads and then laminate the brake 
blocks (parts 22) to the brake hangers/blocks (parts 21) making 
up four left hand and four right hand ones. Solder the base of 
these into the slots in the underside of the body so that they line 
up with the wheels and sit just clear of the wheel treads. I find it 
helpful to hold the brake block with a miniature electrical 
crocodile clip. 

 

  Spring brake yokes (parts 23) between brake hangers and 
solder so that they run towards the axle. The rest of the prototype 
brake linkage is not really visible from normal viewing angles so I 
don't bother modelling it. Make sand pipes from 0.9mm brass 
wire. The top ends are mounted into etched holes on the 
underside of the body and the bottom it trimmed at an angle to be 
just clear of the rail. Fit axle guard tiebars made from 0.9mm 
brass wire.
