Supporting Act
One of my pet hates is poor layout presentation at public exhibitions and layouts that lack integral lighting. I'm also not keen on layout supporting structures that are complicated or 'Heath Robinson' in design, slow to erect and take down or require any sort of tools to do so.
The stucture consists of two end frames made up of 45x20mm PSE (Planed Square Edge) softwood with simple glued and screwed butt joints. The rear uprights stand 1980mm tall, the front uprights 1200mm and are 435mm front to back. The longitudinal spacers and diagonal brace are good quality 6mm birch ply. The front one is 280mm deep and the rear one and the brace are 155mm deep. The rear one is shallower to allow an operator to sit at the layout on a draughtsmans swivel seat with knees underneath the layout. For that reason there is no rear diagonal cross-brace. Being tall and narrow the structure is not overly stable but once weighted at each end at floor level with a couple of 25kg boxes of nails (I'm in the trade!), it's very stable. All bare timber is painted with matt black paint.
The beams locate onto small steel 8mm male/female furniture dowels and are secured by plastic handwheels with M10 male studs which screw into threaded female inserts embedded in the rear of the timber uprights. Nice and easy to assemble and no tools required.
The lighting is provided by 4 x 20w slimline kitchen-type fluorescent lights which are mounted in a 6mm play 'tray', lined with white Formica to reflect the light downwards. I had some of the laminate left over from a DIY project and it seemed easier to use it rather than do several coats of white paint. The tray is stiffened with lengths of 45x20mm PSE down each side. The ends of the tray have 6mm aluminium U-channels epoxied on and the channels simply locate onto the projecting bracket arms seen in the picture. The brackets are 6mm ply and like the beams are attached with alignment dowels and handwheels with T-nuts. The metal brackets seen at the ends are to support the facia panel (see below).
This shot shows the rear of the facia panel. Again it is 6mm birch ply and is faced with white Formica. It attaches to the projecting brackets using interlocking steel 'flushmount' fittings. It's a simple drop-on fit that requires no tools and is held in place by gravity. The lettering on the front of the facia panel (see first picture) are in black self adhesive vinyl and were done by my local signmaking shop. The 2mm and 2FS logos are the latest Association resin-domed layout badges .
This last shot shows one of the protection brackets I made last Saturday to protect the overhanging/cantilevered kickback sector plates. Experience at Shipley showed them to be vulnerable to clumsy operators on adjacent layouts not watching where they were going! These attach to the end frames using the flushmount fittings seen above. They give an indication of track level on the finished structure, approx. 1350mm or 4' 3" in old money
Other jobs to do prior to my next outing at York this Easter include adding a couple of extra 20W lights behind the facia panel to eliminate shadow in front of the station building and adding a small inside shelf at each end to keep my DCC 'tower' and associated gubbins off the floor.

Brafferton Update - 8. Baseboards Pt ii

You can see the section of trackork laid and reported earlier in this series. Unfortunately a small section of it got damaged when two boards fell against each other. I think I can extract a fairly short length and replace it without disturbing the surrounding trackwork. As you can see, once the glue had set and the boards were bolted together, it was all rather solid:

Now to continue with the trackwork. The next board has points. Should be fun...
Brafferton Update - 7. Baseboards Pt i
First job was to smooth all the rough edges off the CNC cut board pieces; tedious but necessary. We also finalised the connection method between boards. This is exactly the same as on Pool-in-Wharfedale, Edward's layout. C&L dowels ensure accurate alignment whilst plastic headed bolts and captive nuts (ouch) secure the join; two of each item at every baseboard join.
The holes machined for the dowels were slightly tight and even when persuaded in with a builder's screwdriver they sat proud of the wood. Edward carefully opened the holes out with a drill and T-bit whilst I sorted the captive nuts out.
All enthused I set to hammering the captive nuts in, being very careful to put them on the inner face of the boards; the bolt will then pull them into the wood when in used and ensure a strong connection. Finished I admired my handiwork; I'd hammered nuts into every single face! Of course we only need them on alternate faces; on the other half the bolt needs to be a clearance fit through the wood. Time for a coffee and then carefully remove the nuts from half of the faces...
Edward also thoughtfully made up two cheek boards. These will enable the boards to be safely held whilst working on wiring etc.:

After lunch we actually did some gluing!...

Brafferton Update - 6. Trackwork Pt iii
Probably somewhat rashly, I have done all this before the baseboard is even assembled. I am hoping that it won't impinge on the construction of the board too much; we shall see!
Next Saturday Edward has kindly offered to help ensure that the baseboards are put together in a professional manner. I shall be whizzing over to Bradford to undertake this task with him. Then I can bodge on with the rest of the layout...
Brafferton Update - 5. Trackwork Pt ii

Similarly, I needed to accurately mark where the track beds cross the board joins; the track starts in the middle, sweeps to the front and then goes back again. This is merely acheived by offsetting the centre of the track circle against that of the baseboards. Again a full scale drawing was made on Coreldraw and the bits I needed (ie the joins) were printed out:

And attached to the actual baseboard with Pritt:
You will note that the template for the joins shows double track; on this baseboard there is only single track, so I have clearly scribbled through those markings not in use:

As I mentioned earlier, the trackbed will be raised up on blocks of ply. Using a steel rule and Stanley knife, I simply scored and snapped multitudes of little ply squares:

Brafferton Update - 2. Design Pt ii
With the change in the geometry of the baseboards, I decided to change the layout design. There would still be three fully scenic boards, but the staging would be on two only and therefore the layout would be more than 50% scenic. I could not now show all of the scenic boards and meet the Layout Challenge criteria. Nevertheless, I will proceed. If I need to designate a smaller area for Challenge purposes, I will cross that bridge when I come to it. Here is my first stab at the redesign:
However the longer track length on the new design got me thinking; could I revisit the actual station plan (ie OS map) and get the layout plan almost to scale length? Here is the 1909 OS extract with various jottings and computations:
Better than I thought! The length from the bridge to the end of the coal drops can be modelled without compression and gives, what I think is, a rather elegant plan:
Now to progress the baseboards. Trackbuilding has already commenced, courtesy of Easitrac, but more of that next time...
Brafferton Update - 1. Design Pt i
Firstly planning. The idea for Brafferton originally germinated several years ago and I've kicked ideas around for quite a while. Whilst the actual station was dead straight, I've always thought it would be fun to build a circular layout. Here is an early attempt to present Brafferton in that format (undated, but probably c.2000):

Much of my information came from the Allanwood Press publication "The Pilmoor, Boroughbridge and Knaresborough Railway" by Patrick Howat. Here is the 1902 Signal Plan fron that book:
If it wasn't for the Layout Challenge, I suspect that nothing further would have happened. With the advent of the Challenge, I set to revising my plans to a. fit in with the Challenge rules and b. to meet my own operational requirements as a portable, exhibitable layout:
I commissioned Alan Smith to laser cut some baseboard pieces for me. At this point he suggested a five piece circle, rather than the six I had envisaged, to add structural stability to the erected layout. Fair comment, but now I would have to rethink my design, and it would take the layout outside the Challenge rules in terms of the total area of layout. I gave the go-ahead to the boards and returned to the drawing-board...

Golden Years
Meanwhile the rest of Bournmoor is in brown-out as we get the similtaneous use of several RSUs. It was interesting as a commited iron-user to see these in use; bravo to Rod for taking the plunge after all of these years. It was also good to see the Judith Edge kits brought along by Steve; a challenge if ever I saw one.
Finally, I managed to get a first view of the baseboards for "Brafferton". Again I've benefitted from the knowledge and skills of members where I have little to speak of! Alan Smith redesigned my boards and I now have five making the full circle. This avoids the layout potentially "breaking its back" as each joint is opposite a solid piece of baseboard; something which six boards singularly fails to do! Alan cut the wood with his CNC facilities making an all but perfect job - the circle is perfect and the edges require only slight sanding to be baby's-bum smooth. Additionally I have taken the opportunity to stretch the scenic section to three boards or 60% of the circle as opposed to 50% originally. This may take it slightly outside the Layout Challenge criteria, but I'm sure I can blag that somehow...
Next step is to get the boards assembled and start on some legs; these should be within my capability (I hope!).

Curves In All The Right Places
The pic below shows the newly installed curved backscene board on 'Niddbeck Bridge'. As previously described this is two thicknesses of 5mm foam-core board made bendy by lots of vertical knife cuts at 5mm or 10mm centres according to radius required. First one thickness was glued into place using PU gel wood adhesive (Bison TimberTix) and held temporarily with dressmakers pins. Once this had set the second lamination was added, PU'd and pinned in place, relieving cuts face to face. Once the glue had set it became a gratifyingly firm structure, acting as a central spine for the whole baseboard unit. The thickness of knife blade used also affects the 'bendability' factor of foam-core board - a thick Stanley knife blade allowing more flex than say a thin scalpel blade.

The shots below shows the double-curve treatment used at each end. My intention is to try and make the layout appear scenically longer than it actually is, by wrapping the painted sky/landscape backscene round like fiddle yard like this, and by making the scenery taper off to next to nothing. Tony has kindly offered to help with the scenic and buildings aspect of the layout, so I'm hoping he might assist with painting the backscene. I've long admired his understated effort on 'Masham'.


I'm presently debating how to clad the exterior side and end edges of the layout. The foam-core board is very susceptible to scuffs and dents, especially when being carried single-handed through doors and loaded into cars etc, so some form of protective skin is going to be required. I think Tony used Fablon to cover 'Masham' ('sticky-back' plastic of Blue Peter fame - remember that?). My inclination is to use Formica or thin plywood.
A start has been made on the station building, or at least the etched windows, doors and bay front that Bob did for me. The platform and cattle/horse dock are next up, or at least the edge bits, so I can then get on and ballast the track.
