An open wagon for bulk loads

7 pieces of engraved sheet material turned into a wagon on bogies.

Drawing and design

fiche with drawing
The above drawing for Fal type 1000 F2 from the NMBS wagon documentation was used as base for setting out a new drawing with milling plan in Corel draw.

photo of Fal wagon
According to the numbers this wagon should conform the diagram but it clearly has different horizontal reinforcements. The type 1000 H1 looks to be closer, photo AV.

This is the Fal type 1000 H1, photo AV.

photo of newer Fal wagon
A CFL private wagon from Arbed where the body conforms the drawing but it has 2 full width operator's platforms and only a single lifting hook per side. Photo AV.

photo of old Fal wagon
Fal 547385 Private wagen from ETL, photo by Geert Nauwelaerts taken in the sixties. It looks like it is renumbered, thus probably taken after 1958 but before the new UIC numbering. The Y25 bogies were not invented yet and it probably has oil bearings, also the UIC lifting hooks were not there.

photo of old Fal wagon
This Cockerill Sambre wagon has the same bogies as the older wagen but with roller bearings, again different pattern on top part and no lifting hooks. It looks to be slightly lower than the wagon beyond it.

new drawing and cutting plan
Screendump of Corel drawing with cutting plan using colours for cutters and depths (note this is not the complete plan as the floor fails).

As you can see there exist a lot of variations with different patterns for the reinforcements on the outside and also having different colours (brown, grey, blue etc) running for various private operators and different steelworks, making it an interesting wagon. The above plan shows the wagon base including a jig for constructing it, mainly using 1 mm ps. The main body consists of 4 sides and 2 sheets for the bottom of the hopper and a wagon floor to sit it on. The plan is showing colours for different depths and cutters. The cutter paths are directly generated in Corel using the contour function. The text documents the various colours, because that is important, but volatile information, which I tend to forget before the project is even finished.
Apart from these 7 base parts there are several smaller details that need to be stuck on such as the internal reinforcements, lifting hooks and levers for operation. The lifting hooks were originally on the hopper piece, but were separated as these turned out to be too delicate and broke off during construction. The bogies are a 3D component and specifically designed for this wagon. The buffers are also CNC milled from PS as done on the Hbikks, this being faster than turning them on the lathe.

ß The complete bogie (painted) as produced by the Anycubic Photon 3D printer

The bogie comes out satisfying but there are anomalies visible, these are not from the printer but are in the drawing due to some unfortunate action and observed too late, this will be repaired in due time. As you can see the springs have too many windings, which is an easy to change parameter in the drawing, all details are there such as the 4 bolts on the axle box, the brakes etc. Who would expect all of this to come out a consumer printer? These bogies are printed upside down, but who knows, maybe vertical is even better, I just have to try and see. Axles are 2mm SA 12.25 mm that run in top hats, the holes for the top hats are already integrated in the drawing.

completed wagon
The wagon body glued together and loosely put on wheels.

The plain underside with the bogies screwed to the floor.

Normally the fiche also shows the floorplan of the construction but that is missing here. However the floor is completely invisible thus in this case I made the floor a plain 1 mm sheet to hold the body and the bogies together. There is a bit of weight on top of the floor beneath the hopper. The bogies are mounted on 2.5 mm turned brass pivots that are screwed to the floor with 2 M 1.4's

 complete wagons
Current situation with a painted prototype.

The photo shows the near complete painted prototype. Some numbers and the paperwork grid and some brake details are to still to do. Weathering will follow as these wagon were pretty filty and dusty with the red iron ore they carried.
This can be the first of a series, although this diagram is of a later built wagon, similar wagons were already in use in the fifties as there exist photos of 21 of these wagons behind 2 type 26 steamers and also as double traction of a Nohab diesel with a type 26 running iron ore from Lorraine in France to the steel works in Liege. Thus an appropiate wagon for a 'Gag' on Fremo meetings.

batch production of sides
Batch production of a series of sides for 8 wagons on the bed of the milling machine.

batch production of sides
Small scale batch production of Y25 bogies with a serie of 10 on the platform of the printer, still wet here before cleaning.
