Cardboard Caravan

I've been doing a fair bit of thinking and research lately in to what shape any future potential layout project will take (I'm not really close to knowing in case you're wondering). A couple of weeks ago I followed a link posted on the NGRM Online forum for a 7mm scale cardboard caravan kit from modelrailwayscenery.com and having seen the largely cardboard 'Moxley' layout at the Sheffield exhibition decided to see what could be made of a downloadable card kit, all in the name or research!

Here's the result, and it wasn't as quick to achieve this as you might think...


Having downloaded the kit and read the instructions I promptly decided to largely ignore them. They say to print it on 160-180 gsm card but I chose to use lightweight matt photopapaper as it has a much smoother surface. This was then stuck to card of undetermined weight but likely 200 gsm+, using an acid free glue stick. Once dry I then opted to emboss the corrugations in the caravan sides and ends to give a little texture. To achieve this without damaging the prints I printed the relevant parts again on plain copier paper and overlaid this carefully on the parts, then went up and down each line twice, avoiding the windows and doors.


Of course this is pretty hard to photograph once embossed, you can just see it around the door here.


You might be wondering why I left the windows and doors alone. Well, the kit includes a full set of separate parts to overlay on top of the sides to reproduce the frames on a real caravan that sit proud of the sides, but they repeat the printed window detail that is represented on the sides. I had other plans.... I did not stick these parts to the card as per the sides, but cut out the centre of each frame and then carefully stuck each group of windows to clear material (possibly an old overhead projector transparency) using Johnson's 'Kleer'. Once dry I was able to cut out each door/window with a frame and glass, the effect of which can be seen here posed on the printed side. The idea is to get a greater sense of depth.


As can be seen, by this point I had cut abandoned the intended style of construction of folding up the floor/sides/ends and adding formers and a roof, as I felt that would produce something rather flimsy. Instead I opted to cut out the parts and use them around a more substantial supporting structure, made from 1.5mm mount board and treated with Button Polish (shellac). This included internal formers to hold the roof in place and strengthening triangles to reinforce the joints.


I had simplified the roof profile from that printed in the kit as it didn't look quite right and it was much easier to create a simple shallow radius. Underneath the printed box that represented the chassis framework in the kit was replaced with a lattice cut from card and more sections of mount board.


In a fit of laziness, and a desire to move on what should have been a simple card kit build that was taking a lot longer than expected, I sprayed the roof and underside of the structure with grey primer. The next day I added all the printed parts and then some carefully folded corner strips from the matt photo paper to hide the corner joins. Once these were dry I ran a pencil over them to tone down the brightness. I then carried out what could have been a ruinous exercise and gently wafted a can of Humbrol acrylic matt varnish over the painted and printed parts to help seal the print and tone it down a touch. This almost went too white but it is generally OK. Once dry I added the window and door units using double-sided tape.


I find that the contrast between the matt of the sides and the gloss of the glazing and the sense of depth between the front window frame and the printed panel behind is almost enough to hide the fact that the interior is not modelled. It would certainly work as a background model and my thinking is that this and the other caravan kits in the range would be very suited to creating a caravan park behind a wall/fence/bush as part of a backscene, using the sides and ends as flats but employing the embossing and window techniques used here.

I've opted to halt at this point until I decide what to do with it. You may have spotted that I've not added any wheels or the jockey wheel, I was thinking of raiding my 4mm scale vehicle wheels to assist with these.

The edges of reason

Just as a coat of primer can really bring together a modelling project and make it look 'as one', a unifying coat of paint around the edges of a baseboard can make it look much more complete.

Matt black, from a Wilko water-based paint, has been applied in two coats and hides the bits of filler, nail heads and some of the differences in material in the surrounding edge of the desk-sitter test track.


Other jobs completed or underway are the buffer-stop posts at the ends of the sidings (furniture dowels filed square on the top section and let into holes in the frame) and super-gluing the majority of the track in place so that the pins can be removed as they are too long and poke out below the board. Shortened pins have been retained in the point and around the magnets.

Phase 1 of construction will be completed once the electrical connections to the board are installed. Then I can think about what, or indeed if, scenic treatment will follow...

Surround and around...

The desktop test-track has been in the workshop this week being fitted with timber surrounds to give it a neat look and hide that it is a bodge of corkboard bits and timber. The end result is a medley of 44x4mm pine strip on the front and right edges, 3.5mm ply at the rear and left back, and similar thickness MDF in the left hand front corner.


Why the piecemeal approach? The original intention had been to use thicker 5.5mm ply as per my dioramas on the rear and left ends with the pine strip along the front (there is a limit to how narrow a strip of ply I can cut!). As the 5.5mm ply is too thick to allow a phono socket to screw in place I used the MDF for the piece where the sockets will be located.


After this piece was fixed in place the decision was taken to use thinner ply on the rear surround so the MDF remains in place despite offering no real advantage (although the drilled holes are probably a lot neater). The thicker ply parts had actually been cut and test fitted in place before the change was decided, hence the title of this post!

KISS - Keep it Simple, Shunting

After weighing up the options for the new desktop test-track outlined last time, I opted to keep it  simple, with the two siding, 4-4 capacity version. This keeps everything very simple and actually looks quite spacious. Using materials recovered from the previous version the track has been laid and the point wired for frog polarity switching via a slide switch. Other wiring is a temporary setup until the fascias etc are added to the board.


MicroTrains uncoupling magnets have been added to both of the sidings. Having experienced issues in the past with the standard length of the magnets matching wagon length making it tricky to re-couple beyond the magnet, I have followed Michael Campbell's example and split a magnet in two by holding it in a vice and giving it a (less than) well aimed tap with a hammer. The resultant less than perfect edge will be hidden as and when scenic treatment is considered. Yes, it is likely to become a scenic test track over the coming months...


You may notice that not all of the track pins are fully tapped in place, officially this is to allow for track adjustment during testing, however there is also the small issue of the board thickness being a couple of mm less than the length of a Peco track pin!

One man's junk... Another man's treasure!

I picked this up at the Sheffield exhibition today for a couple of quid...


I think it is 1/45th or 1/48th scale. I've no idea of the source but looks like a useful supply of parts for 'junk' scenes and I'm having the resist the temptation to plonk the cab and bonnet straight on a Kato chassis as an instant O9 locomotive!

Desk-Sitting - Again!

I have been spending a lot of time recently considering what the next project might be. I've been weighing up various ideas but nothing that has grabbed me as feasible at the present time. Space is still the major factor, along with it being less attractive to be in the workshop in the recent weather conditions. So I've revisited the desk-siting test track concept again, last publicly considered three years ago...

I thought that I had shared the origins of this board here before but cannot find it - it was last years attempt at a desk-sitter using corkboard technology and a bolt-on fiddle stick, but not learning the length lesson from Up-cycle - too much needed to be cleared out of the way to use it! Here it is in original form...


The track has been lifted some time and the board used for the recent tight curve research and Greenwich coupling tests. As rebuilt I have retained a very short extension piece, only 1 1/4" but that is enough to bring the usable length to 25". The extension is fixed in place and could either be boxed in within the backscene and fascia boards or just left hanging out! The extra length allows clearance for a 3-3-2 inglenook with loco+2 behind the first point or loco+4 behind the second.


Alternatively, there is a one point option with 4-4 in the sidings and loco+3 behind the point and perhaps a bit of allowance for an odd longer wagon.


I'm torn between the schemes, the first could be made to work as a shed scene but as a wagon-shuffling scene the sidings look short compared to the simpler plan. The alternative might be a boxfile project but the appeal of a single board is strong. Hmm...
