Imposters on the Bench

Unfortunately I haven't done much modelling of late, lots of reasons, but the result was that I did find myself analysing my current project (the O9 micro roundy-roundy) and whether I had the time to continue with it, do something different or... who knows...?!

The last few weeks have seen a glimmer of hope and a couple of weekends ago I found I had time to sit at the workbench and actually build something. I opted to build another 3-plank wagon based on the one I had completed in January, a nominal 5ft (scale) long wagon with Grandt Line hinges on 3-plank sides. Of course I then decided one wasn't enough so started a second, and to give some variety this is a little bit longer. Detailing is still in progress with the end stanchions yet to be cut back and shaped.


One of the things that test running the new project had revealed was that trains formed of multiple Black Dog Mining based wagons tended to wobble a bit, especially if propelled. Some might say this is ultra realistic but to me it is a bit distracting (remembering that I abandoned using KB scale Hudson chassis for a similar reason). With that in mind for the first wagon I cut up a Peco N gauge 10ft chassis to a 14mm wheelbase and disguised it with Black Dog-style axleboxes, modifying the set I had made last year to try and add to a damaged Hudson frame. Hence this is the first imposter! The second wagon retains the 20mm wheelbase and has steel channel solebars, where there was space to add genuine Black Dog axlebox castings recovered from a broken chassis. An imposter in the sense they are not functioning... Both have weight added in the void between Peco chassis and floor.


The eagle-eyed might spot that there are no cut-outs for MicroTrains couplings on these builds. This is again in reaction to test running, as in order to avoid any accidental uncoupling events, I have opted to use MT couplers at the outer ends of rakes only, within rakes simple loop and pin couplers will suffice. Both new wagons will therefore be loop and pin only.

This leaves a few modifications to do to existing vehicles. I might have over-thought this, but in order to maintain consistency between vehicle ends I wanted couplers that bore a passing resemblance to the MicroTrains box at the other end, which luckily, if you squint, do look a bit like link and pin coupler blocks on real 15" gauge wagons. So out came the styrene and I had a play, having no 5mm x 3mm section wasn't as big an issue as I thought as I fudged up my own from 5mm x 5mm that had already been cut in half lengthwise... More imposters were born!


From left to right:
  • Initial experiments based on MicroTrains 1015 (L) and 1023 (R) coupler boxes. These were actually OK, but the 1015 style one then went on for a bit of further development.
  • Refined 1015 and 1023 boxes. The 1015 (L) now has some 3.2mm channel as the coupler face and whilst maybe not as close as the initial version, I concluded that this could be replicated on the new-build wagons easily. The 1023 (R) has some additional section down either side to reflect the additions I had already made to disguise the actual coupler boxes on some stock.
  • A stand-alone coupler for new-build stock fashioned from 3.2mm channel, one of 5 made for the new wagons. Externally this and the 1015 substitute will look consistent. 
After that burst of activity there will probably be a bit of a lull until I get any more work done, but we shall see...
