There is now a fiddle yard for the layout! The next step is to fit it to the layout and add the tracks, so it's not done, but progress is progress.

Hi Gareth, :)

looks very neat indeed, could I ask you where you intend keeping your layout. The reason I am asking is that I have on many occasions had to store my layouts in the garage. Burntisland is stored in a garage which has some anti-frost heating, but still can have a damp air feel - not the very best conditions to store it, but manageable.

I now varnish all my wood before use and also during certain stages of construction to prevent moisture getting to the wood. The varnish dries quickly 20 minutes per coat - I give two coats normally. Given the tight clearance on your turntable yard you would have problems if it became damp, due to expansion and perhaps warping. The varnish I use is Ronseal Quick Drying varnish. It comes with a tint to represent different types of wood and behaves like shellac. Shellac was used to varnish card and wood in the old days to seal them without distorting the material. (Showing my age here!)

I also store any wood/ply/strip wood on the flat so there is no problem with them before use. (I check for any warping at the buying stage and avoid anything that is not good enough.)

Good to see the progress. :)

Thanks Allan, that's a really good point. This is all built from offcuts from my father's cabinet shop and it's all pre-finished ply. It's rather thick too at 12mm, so I should be ok, but I'll seal the ends of the turntable.

If this is done, you would have to varnish all round, and especially the edges of plywood and the ends of solid timber. I have never found the need to do this but its your train set (or woodpile :))

My stack of timber tends to get out of hand with a lot stored in the garage, with the car which of course will be wet at times, and shorter pieces under the woodwork bench in my workshop. In spite of the less than ideal conditions there are no observable problems with moisture. Traditionally the best way of storing seasoned timber is in a dry place with minimal heating which was always done years ago in schools where the woodwork room would have such a store.

For me 12mm thick is ideal and I avoid using anything thinner especially for a design like this.

Hi Gareth and Terry, :)

Terry is right and has far more experience of wood than I have as he has dealt with it every day for most of his life. I do varnish any freshly cut edges. I sometimes sand off the varnish if the wood surface is to take glue as the varnish would be the week link. The glue would provide the seal to the materials.

We have had trouble with wood swelling on Burntisland despite it being mainly heavy ply, even when the garage it is kept in is dry and has low heating during the winter - no car in the garage by the way. I am trying to keep wood to a minimum on my layout.

I know for some it will appear to be a bit belt and braces, but I am using thinner materials on my new layout and do not want there to be any warping or expansion due to dampness as from time to time it will be stored in the garage room under Grayrigg - I do have some heating there over the winter and it is pretty well insulated :)

Sadly, I have also seen good layouts being ruined by getting wet in the past. Turntable fiddle yards are particularly prone to twisting if not sealed and supported. If Gareth's layout is going to be kept in the house I am sure it will be fine. :thumb

My experience with timber is that for the most part it is over dried within the kilns nowadays ... this is fine if it is going straight in to a nice dry centrally heated house ... but if it is stored in a place with higher moisture content it can swell and twist all over the place. Its a perennial problem with building as the heating comes on relatively late in the process and if the timber is delivered to site before the wet trades have dried out, then even if it comes into a heated and weather tight environment, the higher humidity levels still cause things to swell and twist. WBP and Marine plywoods tend to be more forgiving because of the glue used for the laminations. Not sure what the solution is apart from finding a good timber supplier.

For those who may not know WBP is the acronym for Water Boiled Proofing - a form of treatment for making plywood to an exterior grade and water resistant Marine plywood is waterproof and therefore different to being water resistant. Interior grade plywood is just that and if it gets wet the layers of ply will come unstuck, even if it is painted.

For baseboards marine plywood is probably a bit OTT and exterior grade would normally be perfectly good and is what I use.

The general level of moisture content for timber is between 8 -10 % for timber that is to be used indoors. Yes these things can be a problem with construction timber used in a new building but for our baseboards not usually. As with everything else you get what you pay for. In a DIY store you can probably turn over the timber and select what you need and check for straightness and lack of twist. More difficult if you buy a wrapped bundle of all the same size where the lengths inside may be hidden.

Those with not much knowledge of such places may hesitate to venture inside but usually those who serve the customers will be willing to assist the inexperienced.

I would second that ... :thumb

A few years back we did some checks on "DIY" timber and found it was actually slightly drier than the range Terry mentions and the quality is often poor. As I say, probably not an issue if going in to a centrally heated and dry house ... but if you are fabricating in an in an un-heated space that suffers a little from a damp atmosphere, then you might have problems. Higher quality timber is more forgiving.

The only difference between WBP and marine ply is that real marine ply is hardwood veniers throughout wheras WBP may have softwood interior veniers.

Either I think would be fine for internal modelling purposes.

For those who are interested, yet again it all comes down to the supplier. The classifications purely relate to a broad specification of manufacture. Quality control in manufacturing is key, but also selection of the laminates and voids within the laminates are critical. As with so much, some imports are very low grade but comply with the letter of the specification requirements .... if it is really cheap it probably is.

If marine ply is well manufacture it is better than WBP because of the choice of the lamination material which is naturally impregnated with durable oils and is dense celled ... WBP purely relates to the waterproof bonding. Having said that, some of the hi grade WBP offerings are very good as they do use quality laminates.

I bought 8 sheets of 8'x4' marine ply when extending Dubbieside in the museum. It is much tougher to work, especially if you are hand sawing, but it did provide strong baseboards. :)

I've got some 1/2" marine ply which I've had for over 15 years. During much of that time it's lain outside (It was bought for the boat after all). Although a bit discoloured it's still perfectly flat and with no sign of delamination or other deterioration. It's had no varnish or other protection on it. It's very expensive though!

I have finally finished the wiring. Well, except for the fiddleyard. The points have been finished, the point motors installed, a control box assembled, wires strung around. Lots of work with not that much to show. I have tested most of the layout and things are working well. I can't check the first point yet, it's too close to the fiddleyard. I hope to have the fiddleyard track and wiring done soon, but I'll probably get distracted by something else first.

In the meantime, I have a video showing a bit of testing. Everything's gotten a bit modern for my Edwardian layout, Something else to sort out...

Ah very therapeutic Gareth! Good progress as well, nice to get to this point. I am looking forward to getting there myself. You will find yourself having a nice little play at all odd hours now! Well done! :D

Looking good Gareth, these 'simple' trackplans can be deceptively complex! also far more 'prototypical' than the plethora of 3-ways, slips and diamonds we sometimes see crammed into tiny spaces :o

Can I ask what the overall dimensions of the scenic part of the layout are and the crossing angles you settled on? I'm thinking about a continuation of my plank with a second scene to a mine and this looks to fit the bill!

Thanks Steve! The scenic section is 4'x15" and the crossing angles are all 5. I think all the points are A5, it's whatever Templot came up with. I can send you the Templot file if you'd like.

Today I decided to shorten the main siding at the front of the layout. With the bufferstop in place there was very little room between it and the adjacent building. I didn't think it looked like a reasonable way for any sort of vehicle to access the wharf. I looked at a couple of options and ended up shortening the track by about the length of the bufferstop. I think it looks much more natural and less cramped.

Progress has continued with track being laid in the fiddleyard. I made it over to Scalefour North a week ago and picked up the last package of Exactoscale P4 trackbase that C&L had in stock. This turned out to be the perfect amount to build a three road sector plate. I had considered four roads, but there wasn't enough space between the tracks to handle the stock. I also had almost the prefect amount of rail left over from the scenic section. I still have to wire it up, but trains roll smoothly over the track joints, so things are looking good. Having track on the fiddleyard has allowed me to finish testing the first point and I am pleased to report that it is functioning properly. It's so close to the baseboard edge that I had only been able to test it in one direction previously.
I have found a coupe of wagons, some unfinished, that need a bit more weight as well as a short section of track where the gauge is 19.45mm. Not sure how that happened, but it will be rectified.
Here is the fiddleyard part way through tracklaying:
