DOGFISH Instructions
1. Take sides/ends (A) and fold to shape (drw1), next take the two side-end assemblies and solder
together to form hopper body. (drw 2).
2. Take solebars (B) and fold to L shape, so that the half etch detail forms the long part of the L
shape and the full etch forms the base of the L shape. Therefore fold along the joint between half and
full etch see plan. Then take chassis (C), push out rivet detail on buffer beams. Now fold up bottom
lip on buffer beam then fold buffer beam thru 90 deg. Also fold hopper bottom sides through 90 deg.
(drw 2).
3. Next solder solebars to chassis (C) between buffer beams and up against hopper bottom sides.
(drw 2).
4. Now fold inner chassis members up to form section channel.
5. Next fit hopper body into chassis assy. The tabs (X) fit into the slots (X) with the base end of the
hopper body resting on the chassis. (drw 2).
6. Now take side stanchions (D) these fit into slots (Y) on body sides, when fitted add plates (E) to
body side, these fit to half etched slots in sides and fit over top of stanchions (D). (See photos and
drw 2/3/4).
7. Now take end stanchions (G) 4 of and fit into slots (Z) on hopper ends. (Drw 2/3).
8. Next take end stanchions (F) and fold to shape, which fit into the half-etched recesses at outside
edges of body. (drw 2/3).
9. Now solder outer end stanchions (M) fold to shape (2 of, note that they are handed) from hopper
body to chassis at deep end of hopper body. (drw 3/5).
9a. At this stage you can fit the discharge floor assy. Fold up floor etch to shape to match the profile
piece supplied (side a to side a). This then fits into bottom of hopper body also noting which way
round see drawing 5.

10. Next take vac cylinder support (T) fold up and fit vac cylinder casting then fit to chassis behind the
above stanchions as shown in step 9. (drw 3/5)
11. Take the other end stanchion (H) bend outside parts through 90 degrees. Then solder part (J) to
part (H) so that the central hole aligns then take complete assembly and fit to hopper end, shallow
end to hopper body. (drw 4).
12. Take 0.7mm brass wire and fit through holes in part (J) and angle wire down to hopper bottom
plates. (See drawing 4).
13. Now fit hand wheels (P) to wire ends.
14. Bend up to shape the hand rail support stanchion (L). , and fit to wagon end. (The same end as
the hand wheels). Add 0.7mm wire handrail as per (drw 4/5) also add the other two handrails which
go at this end of the wagon, (see drw 4/5) which are also made from .7mm wire.
15. Now bend up the step assy. (U) and fit to sole bars at the wagon end that has the control
handles.
16. Also bend up and add to solebars the consignment clips (S), these go at the L/H end of the
solebars see photos for position. (drw 5)
17. Next add the buffer castings to the buffer beams and also the lamp brackets (R) which fits into the
slot on the buffer beams.
18. Now take the hand brake wheel supports (N) drill a 0.7mm hole at the pointed end and fit these to
the solebar from the inside at the other end to the steps, (for positioning see photos and drawing).
Now pass a length of 0.7mm through holes and attach to end of wires the hand brake wheels (P).
(see drw 3/5).
19. Fit the wheel sets to the axle box castings, remembering to fit the top hat bearing. The axle boxes
go inside the solebars aligning them to the rivet detail on the solebars. Check all is square and all the
wheels touch when placed on a flat surface.
20. Next make up the brake shoes, cross ties and brake links as per drawing 6. You will need to
make from bits of scrap etch small platforms to mount the brake shoes on see drawing (6).
21. Finally add the coupling hook and chain.
