A couple of months ago, with a 16mm sugar cane event looming in June 2017, it became apparent rolling stock was required. Precious little is available in kit form or ready-to-run, and drawings or any technical data of prototypes are thin on the ground.
Researching into the wonderful CaneSIG website run by Lynn Zelmer, some field drawings are kindly made available. A wagon type used at Moreton Mill, Queensland, Australia was deemed suitable to build and, once the drawings were converted to 16mm, materials were obtained.
Wooden toffee apple sticks, wooden coffee stirrers, lollipop sticks, Roy Wood Models steel wheelsets, Tri-ang Big Big Train plastic wheelsets, Cambrian Models axle boxes, jewellery chain, and superglue.
The wagons were split into two batches: 19 with steel wheelsets and 21 with plastic wheelsets. This helped to break up the tedium of building en masse and reduce overall costs.
Having calculated the prototype coupling height and my own insistence on using Tri-ang Big Big tipper wagon wheelsets, axleboxes proved to be a sticking point. With such a large number required, I decided to buy some in. Fortunately Cambrian Models were able to quickly design a Hudson ‘Faro’ type to a bespoke size and 3D print all 40 wagons’ worth within a couple of weeks.
Having cut and marked all of the parts, the axleboxes were first glued to the toffee apple stick side frames, the wheelsets inserted and the end frames glued onto the side frames. This has to be done in one swift manoeuvre, aided by markings on the frames for centre (allowing enough room for free running and lateral play), whilst checking for square on all planes of the model with particular attention to all 4 wheels. A flat work surface is helpful here, working with the wagon upside down. This is all very difficult on the first wagon and requires a level of dexterity to hold several parts simultaneously, but a routine is quickly established.
The stanchions (toffee apple sticks again) add vital extra contact points between the side and end frames. Without the stanchions it is more likely the frames could be pulled apart by the drag created in a long rake of wagons.
Four coffee stirrers act as the planking, with a lollipop stick as the larger central runner.
The buffers are two toffee sticks glued together, sanded to shape and glued to the end frame. A few wagons sport prototypical hook couplings under the buffer, but these are non-functional. Each buffer is fitted with a familiar top hook and chain coupling.
The winches were constructed from two ends of coffee stirrers and a short section of a wooden skewer. The jewellery chain was attached at the non-winch end with an eye pin and pulled tight to wrap around the winch, supergluing in place. Each wagon received a running number and white frame ends, painted on using white paint on a cocktail stick and a correction fluid pen. The first batch of wagons received some bolt head detailing.
The final results
All running tests were successful with the steel wheeled wagons running exceptionally smoothly. Despite their incredibly light weight they are safe in numbers and proved themselves at the sugar cane event. They are not perfectly prototypical however, and nit-picking will reveal missing X bracing, missing steel underframe bracing, and other marginal errors. I feel this hasn’t detracted from the overall result and they are easily identifiable as cane wagons.
Since the event, the wagons are now gradually gaining sugar cane loads in the form of coconut fibre normally used for pet bird nesting and dolls house thatched roofs.
