    The first area to be 'terra-formed' has now been done.
     
    Two of the main reasons for doing it this way is for lightness and durability. Using traditional plaster bandages, they're too easily damaged as I found out on Matford. The whole area is only supported along the edges with the chicken wire doing all work keeping all in place. It may need an second coating with resin as I've missed a few bits here and there. I'll see when it's all cured nice and hard, and of course it adds virtually no extra weight.
     
    The materials that I've employed are used in the marine repair business and are freely available from any good chandlery.
     
    The chopped strand fibreglass matting is impregnated with polymer resin & catalyst and forms a very hard and durable surface. The job ideally should be done in the open air as the smell is very persistent. At the moment the section is in the garage while it cures but with all the doors shut I can still smell it! Hopefully by tomorrow that should've disappeared.
     
    Next to come will be brown earth paint prior to gluing down hanging basket line similar to the old hairy carpet underlay.
    Then it will be selectively pulled off and treated with various scenic methods. I intend to experiment with the 'Grasmaster' used on top of the pulled off liner.
     
    There still a lot more to do with the main structure before any scenics are done.

    We've taken the decision to take Matford off the exhibition circuit for the time being and to 'do an Eridge' and rebuild it. It has been suffering from several problems in the baseboard department. Firstly we used the dreaded MDF which has swollen to at least +1mm and in some places more. This is due to our proximity to a salt water atmosphere. In hindsight, perhaps these problems could've been avoided with the MDF had we sealed it all, after cutting, with varnish at least.
     
    When this problem was discovered we had already half built our replacement DRAG test track for which we were using MDF. So all the boards were thoroughly treated with GRP resin and painted with marine quality paint. These are problem free with good track alignment and work perfectly well considering that they are erected and dismantled twice a month. The original suffered from poor quality deal softwood framework, which ended up looking like the waves of the ocean. So the lesson was learnt that always use the best materiel that can be afforded.
     
    The second serious problem was that the side/box frames were made from a synthetic materiel (flooring laminate) which not only warped, it took on a banana shape. It was assumed that such a materiel would be stable, but no so. Avoid it like the plague! We rebuilt the board 'undercariages' with marine ply framework. This improved matters somewhat but the constant expansion on the MDF baseboard top still caused alignment problems. Each board top has subsequently taken on a saucer shape.
     
    We are rebuilding the baseboards with the 'new' polyfoam principle, as used by Gordon Gravett on Pempoul. It consists of 1200mm x 500mm x 50mm thick pink polyfoam insulation.(I gather that it's also available in blue, but I've never seen it!). The framework is made from 4mm thick x 100mm deep quality ply glued on with solvent-free grab adhesive. (No More Nails type) To avoid having to hold it altogether whilst the glue goes off with clamps, we have used 3-4 inch long wood screws No 14/16 size which have a large coarse thread, screwed in along the ply sides at 100mm spaces directly into the foam. It's dense enough to allow a very strong grip and bite for the screws to allow the go off. After this has happened the screws are removed for re-use.

    These show the style of construction. They are to be used on the Balcombe Viaduct project. The ply top strip is for the 2 track plain line. They have been made now for over a year and kept in a relatively damp garage without any sign of movement. In fact it is almost impossible to put in any torsional twist.

    Another problem that has come to light is that not all code 82 flat bottom rail is exactly the same. We found that we had used Exactoscale track bases and used C&L rail which is 0.2mm thicker at the rail head, thus making the track 0.4mm tight to gauge. Not acceptable when working in P4! So this also made it easier to decide that a complete track rebuild was also neccessary.
     
    All the buildings and as much of the scenery as possible will be salvaged and re-used. We want to preserve the essential 'look' of the layout.
     
    That having been decided we sought advice from CK of this parish for his expertise in assessing what 'might have happened' had BR remodelled it all in the early 90s. This was bearing in mind the cost cutting and removal of expensive to maintain S & C work that 'would have happened'! To this end the complex pointwork at the fiddle yard end of the layout will be removed (three-way point and other under used pointwork) and will be replaced with a simple crossover on a new extension board between the FY and the current first scenic board and a new pointwork to the up and down sidings in flat bottom leading to 'older' bullhead trackwork.

    This is the pointwork that is being replaced. You can see the track alignment problems from this snap. (ctsy David Brandreth)
     
    This is the first bit of new pointwork (new crossover) made in copperclad FB. It is a BV 10 (1 in 10 angle). Next all the cosmetic bits and pieces will be added. Colin Craig cast 'Pandrol' fittings with clamplocks, and backdrives using Brassmasters cranks all non working! Once all this is done the whole thing will be mounted on 4mm ply and the Tortoise (or the new Cobalt) motors added and fully tested before fitting and gluing to the polyfoam baseboards. Thanks to my old friend Brian Harrap (ZOB and Quai87) for his invaluable advice in F/B point construction.

    New sand drag in the bay platform. Brambles need trimming! The little bit of vertical rail in the ballast is a stop in case a unit overruns..or an operator not paying attention! It will be incorporated in the framework for the double red stop lamp, based on the one at St Ives.
     
    New replacement fencing made from brass square tube and fine dressmakers mesh fabric. The grass along the bottom of the fence was done with the 'Grassmaster' using the cone accessory.

     
    Anti vermine netting fitted. As at Cam and Dursley Station

    Some more trees and an armature for Balcombe. These are all experimental ATM and will be placed at the rear of the layout. I've still got to improve on tree recognition and produce better models of particular types.
     
    Some of these will probably be removable for use on other projects. The smaller ones will be used on the Matford rebuild on the new extension board.

    After the first attempt at tree making using Gordon Gravett's methods I wasn't happy at all with the efforts. Some had the 'broccoli tree' look whilst others looked too dense or with too much 'space' and with the wrong colour foliage! Using the Woodlands 'foliage' just doesn't cut it, at least until I can master a better technique in using it. The Monterey pine has been sidelined with it's dark Woodlands foliage, as it all looks too flat.
     
    The ones illustrated here have all had their original foliage stripped off and replaced with teased out postiche (theatrical hair) with Green Scene scatters added.
    When I was at a Netherlands show recently, I was advised by Mr 'Anita Decor' that when using postiche and you think that it's finely teased out, do it some more until it's almost falling apart and then you've got it right.
     
    The same armature with adjustments and the foliage re-done using Anita Decor brown postiche and Green Scene 102 scatter. Still not quite light enough!
     

     
    The pine needs a different style of foliage. The left hand one has had the Woodlands 'foliage' changed for Green Scene postiche and their scatter.(below)
     

     
    Before and after. The postiche still needs to be more teased out.

    Thanks to Andy for sorting access to our blog problem. I have already posted this by way of the 'edit' feature, but anyone who might be interested will not have been notified and it will have slipped out of sight. Apologies to those who may have seen this already.
     
    Here are some more snaps of progress. A few more clad with brickwork along with the first couple of the 'longer hole' piers where the hole goes into the supporting plinths.
    It's been very difficult to clad the piers properly when using Staters embossed Plasticard. As discussed on a previous thread the brick course alignment is absolutely appalling. discussed here If it wasn't for the fact that we'd already purchased a large quantity of it I'd bin it all. Never again! Surely Slaters should be looking into it and getting new 'moulds'. We (the hobby) has long patronised them and I feel that they should at least supply us with accurate materials! Rant over!

    The first baseboard has now been built for one of the 'generic' scenery sections. It has worked out very well indeed. Pink 50mm polyfoam insulation board was used, (available from B&Q at about £20 for a pack of four [1200mm x 500mm]). 100mm deep 4mm thick birch-faced ply was glued to the long sides with 'No More Nails' type solvent free grab adhesive and 9mm marine ply was used for the 'FREMO' style ends, with patternmakers dowels fitted.
    Underneath transverse bracing was fitted (6mm thick x 50mm deep) to stop any torsional twisting
     
    The polyfoam is dense enough to take 4" x no12 screws which would grip sufficiently to allow the side/end panels to be screwed tight enough whilst the adhesive takes. This saves a lot of clamping up. The bonus with this type of construction is its lightness. Upper scenery, embankments, contours will be made from the conventional white polystyrene, the sort available from builders merchants in 50/100mm thickness 2440x1220mm size sheets as it's a lot cheaper.
     
     
     
    The next one that will be made will built allowing for an 'under rail' type bridge. Not quite worked that out yet!
     
    All in all, I'm very pleased with the final thing. I got the idea from an old issue of MRJ, which showed the construction of the baseboards for Gordon Gravett's 'Pempoul'.

    You can see the 'run out' of the Tillig superelevation strip. It starts at a point halfway along the transition curve and works very well in high speed 'push along' mode! If you are going to try this, when gluing the track to the strip with PVA glue (plenty needed), a lot of weight will be needed during the drying time, as the inner edge has a tendancy to lift if you don't!
     
    Meanwhile a few more snaps of progress. More edging fitted and painting.

    Here are a couple of snaps of a typical FREMO set-up. 'Hölle' in P87 was seen at Utrecht last year, with a known reprobate playing trains!
    This bit is only about a 20th of the whole project! There are interchangable sections which are cleverly 'scenically blended' This one was the best that I've ever seen with such good scenic continuity. Some that I've seen in the past have looked like a patchwork quilt!
     
    We would devise our own profile for baseboard end plates, rather than using the 'laid down' profile. Basically it will allow us to lengthen/shorten the layout by making interchangable generic scenic boards.
  10. Re6/6
    Here is the first attempt at a tree armature, following Gordon Gravett's methods (with a few variations in method) shown in his new book.
     
    I can't recommend this book highly enough as the definitive 'how-to' work on tree making. I couldn't have achieved anything without it's guidance.
     
    This is an attempt at a 'grisly' old oak. The small lumps need removing from the thinner wire bits. The 'greenification' is still being worked on for the right formula.
     
    We'll need a large quantity of various trees for Balcombe Viaduct, including some old large oaks, elms and some smaller silver birches. The GG method ones will be at the front and then blending into lesser ones, probably using quite a lot of sea-moss built ones.

    The Dawlish Donkey summer charter visits Matford. This was a public service that ran between Exeter and Newton Abbot during the summer months a few years ago.
    The lovely little 14XX belongs to CK. This will run on the layout as a shunt and release move to bring some added and unusual interest!
  12. Re6/6
    New backscene will be needed. Much 'squaring up' and 'bedding-in' to do. It was all thrown back together in a hurry for the show. The photos were taken by David Brandreth of the Scalefour Society at the 2010 Exeter show a few weeks ago.
     
    A couple of general views of layout from buffer stops, looking towards fiddle yard (aka Exeter City Basin Jct):


     
    View of the station area, with Class 170 and 159 in evidence, clearly SWT are holding sway at the moment! The Class 170s were seen at St Davids for a short while on Waterloo services - that's all the excuse we need to run one on Matford!

     
    Class 08 passes evidence of disused oil depot and a folorn PW hut, which is unlikely to see much use by Network Rail anymore. The brambles and hut are a new addition to the layout, the brambles were created using fine horsehair and some Noch scenics purchased in Holland.

     
    The ex-Central Trains Class 158 waits to come off depot and join the main line, whilst the 08 shunts the scrap metal siding (although the wagons behind the brake van appear to be unusually early from the period and were loaned by a certain Captain of this parish!):

    Centre section cladding completed. Some more work still needed here and there, but I think that we're gradually getting it how we want it.
     
    Some expermintation has been done with the primary undercoating as it's important to get the base colour just right when finishing with light airbrush misting. The real thing is like a 'patchwork quilt' of colours. Light browns, oranges, greens, limescale staining, even with engineers blue brick in repaired areas and even individual differently coloured bricks.



     
    In the 'real thing/model' argument one has to be careful not to overdo the colouration and contrasts. Still we'll see when we get to that stage!
     




     
    Classic view!

    Approximate ground contour.

    The first few plinth/pier combinations are assembled. The M4 rodding is used to adjust the positioning whilst the assembly is glued up.
     
    These will make up into the middle 9 arch section.
     

     
    The classic view. The holes will have to be tidied up prior to being clad with English bond plasticard/SE Finecast vacuum formed plastic.

    Still more fun and games last night. We still have one or two electrical snags to sort out but generally speaking that's it. We're in business . A paint touch up will come eventually. We were pleased to welcome a member of one of our neighbouring groups from the Mid Devon Area . David B brought along a lovely part finished Mallard GW steam Railmotor and a couple of etched brass GW engineers wagons (Haye Developments). I'll ask him for some snaps.
     
    Apologies for all the chattering row. It's impossible to get them to shut up whilst filming!

    With S4um looming rapidly, there's still a bit to do. The latest structure is the loco fueling point, replacing the old adapted Knightwing kits which have passed their best. The new one re-uses the original roof and a couple of the salvagable small cabinets. It's made from a sheet of PCB with fine angle brass H-section soldered on.
     

     
    Still to be 'planted' and 'vegitated'

    With very many thanks to Jim S-W of this parish for his designing the artwork and commissioning this first test etch which arrived yesterday. Lovely they are too.
     
    Here are a few snaps of the etches.
     

    Each brick arch is etched in two parts and tacked together to give the level change in the brickwork.
     
     

    Arches for the characteristic 'holes' in the piers
     
     

    Beginning to look like the effect that we're after.

    A 'visitor' arrived yesterday. A hotch-potch plonked on the viaduct just to get the feel of what's to come!
    Hopefully the next 'visitor' will be the much loved blue and grey set!
