What is a Cornish Hedge

This is all a little advanced to where I am with this project but as you may have noticed my mind does race ahead of me at times. Anyway I do feel I need to plan ahead a little before I embark on any baseboard construction. I've been considering some of my planned scenic items and how they might affect the baseboards, thoughts have wandered to the lane at the right on the Tredethy Wharf layout.

Last time I was at Hellandbridge I remember the approach down Tredethy Road from Helland being a narrow Cornish lane. Each side of the lane being bordered by typical Cornish hedges and, in places, trees hanging over the road giving a secluded valley feel. But three questions come to mind;
What is a Cornish Hedge?
How is it constructed?
Are the lanes slightly below the surrounding landscape or are they just high hedges?
Hopefully know the answers to the above will help me model one.

While driving along these lanes I've never been that observant, I've probably just been concentrating on not hitting them while avoiding any oncoming traffic. A little research found a couple of interesting web sites that I hope will help me. Nothing will replace good photos (dear partner this is a gentle hint, can we get down there this year?) but these do give details on how the hedges are constructed.

After looking at the above sites I think I can say that, in brief, a typical Cornish hedge is a hybrid between a stone wall and an earth bank. The hedge sides are typically built tapered with an inward curve from the base to half-way up. The top of the hedge is normally about half the width of the bottom. The base is created by placing large stone blocks into the earth and packing them in with sub-soil. The sides are then built using smaller rocks that interlock randomly. When the hedge reachs the required height, the random laying of stones turns into neat rows of square stones called "edgers". To finish, grass is sliced from the ground and stuck on top of the structure with sticks. The internal core of the hedge is earth.

There is a good cross sectional diagram of a Cornish hedge here.

What we see, as we travel along Cornwall's lanes, as a green hedge is the result of years of vegetation growing on/over the base structure.

Well you learn something everyday.........This is what I like about this hobby, it's not just about the railway with its track, locos and rolling stock, it gets you looking at and understanding your surroundings.........

RCH 7 Plank Open Wagon (Pt.2)

Unfortunately, due to problems at work, I was not able to get to this month's Scalefour Area Group meeting (Sorry guys). When I eventually arrived home I thought I'd to try and make the best of a bad day.

The RCH open wagon was still out on my bench so I drilled out the buffers and glued then in place. While the glue was setting on the buffers I fixed the solebars in place (these had been prepared a previous evening). Finally, with a little filing off the ends of the floor and solebars, I glued the sides onto the wagon floor. I felt I made a bit of a meal putting the sides together as I was dry run testing different methods to get the sides true. Eventually I think they look OK.



I then started to prepare the axleboxes and springs for fitting onto the W irons but realised the ones I was using had 5 leaf springs and pressed shoes. The plastic moulding supplied with the kit are only 4 leaf springs with shoes that possibly represent cast shoes. Hmmm.......is the kit correct? Out came my wagon reference books only to realise I don't have a reference photo of a fixed end RCH wagon!!! D'oh....That should have been my first thought when starting this kit.........have I any references that I can base this kit on?

It was getting late so I stopped at that point. Only a small amount of progress but it was a bit of good therapy at the end of a bad day.

RCH 7 Plank open wagon (PC73)

To start the year off I've opened a wagon kit, dug out some old D&S compensation units along with Kean Maygib sprung buffers and made a start. This is a Parkside PC73 RCH 7 plank wagon with fixed ends. I'm sure one of these would have turned up at some point on the Wenford branch.

The mouldings are very crisp and the kit is supplied with w-irons and springs separate to the solebars which is a nice touch. I've soldered up the D&S W-iron compensation units, soldered the wheel bearings into the w-irons and popped in some Alan Gibson P4 8 spoke wagon wheels. I've also cut out and filed down some of the webbing from the underneath of the wagon floor. The aim is to have this as an empty wagon so I need to try to keep the internal planking detail. Then using the excellent Brassmasters Axle Spacing gauge, which I picked up at Scalefour North last year, I fixed the w-irons onto the wagon and ......... hey-presto ......... one nicely running wagon, well ...... a nicely running wagon floor.

This is the first wagon I've built for nearly 20 years so I'm taking it steady but I've started to prepare the sides and solebars. Hopefully another evening will see these in place along with the buffers.

I'm just trying to decide whether to use plastic axleboxes and springs or use some MJT castings ....... May well use the MJT castings as they should add a little more weight to the wagon and could be less hassle to fit.......Hmmmm...........?

Walls and Hedges

I'm having to spend some time this Christmas on a wargaming project. Painting some walls and making some hedges. Realising that this is all good practice for the forthcoming layout I thought I could justify posting my efforts.

My wargaming partner painstakingly carved a number of masters out of wax for these walls and from these we created moulds. The walls are then cast using plaster and painted with a number of acrylic colours before the bases are flocked. I'm practicing taking photographs with my girlfriend's camera as my camera has finally given up. The photo above is a little bleached in colour, the walls are a little warmer, but gives a reasonable impression of the finish.

The hedges are simply made from kitchen scouring pads and flocked and stuck on card bases. Wargaming structures do have to be more robust than those seen on a railway layout as they are constantly handled. Which does make me think that this is not the total method I will be using for hedges on the layout but I may use something like this as a base for hedging.

Groundwork

Just been thinking through how I'm going to construct the baseboards. Last time I built a baseboard for a layout it was in the days of 2" x 1" timber frame topped with chipboard. I keep reading about how important well laid track is for smooth running (which does make sense). So I figure that a flat, rigid baseboard that (hopefully) will not twist or warp has to be a basic requirement.

The above diagram is my first thought, nothing new as it's all been done before.

Cross beams constructed from plywood and softwood creating a sandwich. The track bed will be supported by risers and also fixed to the 'Back facia contour board' to create an 'L girder'. The 'Front scenic support board' will be fixed straight onto the cross beams and also to the 'Front facia contour board' again forming an 'L girder'. I am hoping that the combination of the cross beams and 'L girders' front and back with give stiffness. I may cut some circular holes in the 'Scenic support board' and cross beams to reduce a little of the weight. Polystyrene packing will be used on top of the 'Scenic support board' and 'Track support board' to form the base for scenic material.

I would like to have the Backscreen curved around the corners from the back onto the ends. At the moment I have a bit of a blank in how to do this. Using hardboard for the backscreen is a thought and curving this between the plywood 'Backscreen support board' and the 'End board'. Problem is it will be a very tight curve and until I get some hardboard I won't know if that will work. May just use some stiff card pasted onto the 'Backscreen support board' and 'End board' with a plywood former at the top to help create the curve.

If anyone has any suggestions or can see pitfalls please comment.

Unbalanced picture

I've been looking at the plan of Tredethy Wharf again and I agree with Trainspotter-USA that the layout is a little unbalanced. With buildings on the right and open country on the left the weight is on the right, never the less I think it should be OK.

The line at this point in the valley does pass though open country before entering a wooded area again. I've discounted a line side hut with some platelayers in attendance as I'm not sure there were any huts on this line. There were no signal boxes or signals on this line either. There was an interesting watering point at Pancarrow Woods further down the valley, stage right, between Helland and Boscarne. Not sure I could justify moving this further up the valley. I know it's my universe but I'm also trying to keep it reasonably close to reality. I'm struggling to find anything else to put at the left other than suggesting the line is entering a wood.

There are some interesting trees that feature in photographs on this line. I've not yet identified type of trees but my hope is that I can create a couple of them and plant them mid left to help balance the picture a little.

Tredethy Wharf

Oh no not another plan.......... Well let's hope this is it..............

After finally making it to the December Scalefour Area Group meeting and riding the initial comments of 'Who are you?' and 'Hello stranger', I was treated to some advice........ 'You need to get something running'. Well, I must admit, I have been beating about the bush a bit, and probably spending too much time composing blog entries although it has all been about setting the scene and developing my world around Grogley Junction. I do feel it is coming together but the guys are right I do need to get something running. I was impressed with Gordon's Fish Dock shunting puzzle layout as a quick essay in layout building and came away with renewed thoughts about trying to build an Inglenook Siding style layout.

Over the past couple of weeks I mulled over the question: What to build? What ever it is, it still has to fit the following parameters:

1) Be part of the overall project so any stock can be used on subsequent layouts

2) Be smaller than my original proposed Boscarne Junction starter layout

3) To be achievable as a first project.

The story so far with the different layouts:

Grogley Junction? Far too big and advanced for me at the moment.

Boscarne Junction? Considered too big, but have not totally discarded the idea.

Polbrook Engine Shed? Discarded on size and I'm not sure it fits in with the project.

Wenfordbridge? Would be nice but even when compressed, with the scenic section at 12ft long, it's too big.

Ruthernbidge? Again too big.

Nanstallon Halt? Nice but only one siding, so minimal operation and could well end up with more hidden sidings than scenic section.

Dunmere Junction? It is what it is, a junction and even if extended to Dunmere Wharf would only be one siding and become too big.

Dumere Halt? Again nice but no sidings.

While all these thoughts and plans were being mulled over there were two photographs in my collection of books that kept popping into mind. That of a Beattie Well tank crossing the road at Hellandbridge crossing and a Beattie Well tank shunting at Tresarret Wharf, both on the Wenfordbridge line. I've been intentionally avoiding any serious considerations on this line due to it being a 'goods only' line. I then suddenly saw this as an advantage. With the pace I've been working and time available it does considerably reduce stock requirements. So how about combining the two images into a fictitious wharf on this branch? Recollecting that Tresarret Wharf had a siding removed in 1932 .... eureka ..... there was my Inglenook siding layout. OK not exactly the 5:3:3 ratio of the original Inglenook but never the less it is in a similar style.

Ultimately this will need hidden sidings at each end to allow through workings of china clay trains but on its own, without the hidden sidings, I think it could be a small shunting puzzle. Not a very complex puzzle but something to operate in 7ft. The loop holds three wagons, the siding holds seven wagons. I may take up a two to three wagon spaces at the end of the siding with a small unloading vignette. From the left hand baseboard edge to first point there is enough space for a 57xx and three wagons. At the right hand side just enough space for a 57xx and one wagon. I know the 57xxs didn't work this branch but until I purchase a suitable loco I'll have to make do.

Why Tredethy Wharf? .... Tredethy is the other side of the river to Helland. My alternative history is that Tredethy financed the bridge across the river Camel and so this area became known as Tredethybridge not Hellandbridge. Hence the layout being named Tredethy Wharf .... tenuous I know and I do apologise to the inhabitants of Hellandbridge for taking this liberty.

So in reality this layout is set at Hellandbridge but with the wharf siding the other side of the road, not behind the farm buildings as the original siding. My Tredethy Wharf siding would have stayed open until 1970 which was when Tresarret Wharf closed. This will allow me to build a loco roster consisting of a Beattie Well tank, 13xx tank engine, and Class 03, Class 08 diesel shunters. I will probably only need a selection of fifteen wagons before embarking on building a couple of rakes of china clay wagons. The layout is much smaller than I was hoping but more than enough to keep me going for the next twelve months.

Better get an order off to P4 Track Company for their new line in turnout chairs then start building the baseboards..............
