Junkbox Jury - a Tale of Two Coaches

Another raid on the junk box (well, it's more of a drawer...) revealed a half-started wagon body, 56mm long and 26mm wide, with a single-plank top. I started to consider using it as the basis for a 4w coach for use behind my FK3D Simplex on 'Odsock Corner' so I carefully removed the sides. However there were traces of damage along the floor edges so to make a fresh start I re-scribed the planking on the other side.  

The style of the coach follows that which I described in the 7mm NGA's 'Going Minimum Gauge' and I opted for a total coach width of 26mm, thus reducing the floor to 24mm wide. Side and end pieces were marked out on 40 thou styrene and rather than the 18.5mm height I had used in the article, I reduced this to 16mm. When mocked up next to the loco it looked too low, so new set was produced 18mm high and duly assembled. Seating planks came from another wagon floor previously scribed onto 60 thou material and cut to 24mm x 8mm sections.


Having assembled the body I realised I had dropped a clanger. This was meant to be part of a project to introduce a few 28mm wide vehicles into use. So another pre-cut floor was found, but this was a little shorter, even after adding an extra plank (from yet another floor, I can't help myself!). The new floor was 26mm wide and again a set of sides and ends were marked out at 18mm high and assembled around it. The rest of the other floor became more seats. Seat supports on both vehicles are 20 thou styrene cut to 8mm tall and set around the back and edges of the seats. 


Where the shorter, wider vehicle differs from the first is the underframe, using 3.2mm channel section and 4mm deep 40 thou bufferbeams, whereas the first uses 3.2mm 60 thou styrene strip for both.

The second vehicle is much better proportioned when sat with the Simplex so detailing continued to bring it closer to the paintshop stage. On the bufferbeams I added slithers of 25 thou styrene rod to represent bolt heads in line with the solebars and above the coupling area. Further bolt heads were added on the solebars above the axle box locations, but you cannot quite see them in the picture!


A Peco N gauge 15ft wheelbase chassis had been attacked modified some time ago to accommodate Mathieson 7mm wheelsets, remove all the brake gear etc and shortened at either end. It fits almost perfectly between two platforms added behind the bufferbeams to support the couplings. The axlebox and spring detail was removed and replaced by 4mm scale castings from 51L/Wizard Models. The chassis and weight were secured in place with epoxy adhesive, but not before extra weight was added along the edges using self-adhesive window 'lead'.


If it ever stops raining I will venture down the garden to the workshop to give it a coat of primer.

The original build will be put to one side for future development. There is a slight irony that in trying to use up the contents of the drawer I've created a new, fairly complete, candidate for it...
