  1. Early railway companies were usually launched in a mood of heady optimism, only for the disgruntled shareholders to learn that building the damn thing was going to take a lot longer than anyone had expected. You may have noticed that the Middenshire & Fiddleyard Trunk Railway continues this venerable tradition. Even so, taking 18 months to ballast two foot of track did rather play on my conscience. I decided to tackle the problem with sheets of Poundland sandpaper. Early railways completely covered their sleepers with ballast, so I figured I might as well use paper inserts and have done with it. I don't expect my layout will get too many knocks and all my locos moved out of warranty more than forty years ago, so I'm prepared to try this idea out - but at the risk of stating the bleeding obvious I guess I should point out that delicate precision mechanisms and abrasive flakes of grit may not be the best combination for prized locos. This is an experiment to test whether it really is possible to seal the surface of the sandpaper so it's not a risk to stock (nor a constant source of tidying up). The sheets of sandpaper come in an assortment of grades, and I used the fine sheets for this project. I'll explain this choice and discuss whether I should have used a larger, coarser grade in my next post. The sheets have thin backing paper, making them easy to score, easy to cut – and also quite easy to tear. I shook them and vacuumed them to get any loose grains of sand off the paper, then sprayed glue over the sheets to try and fix all the remaining grains in place. (Matt vanish works as well, but I had a spare can of spray mount glue to use up.) Here's my recipe for anyone reckless enough or desperate enough to consider sandpaper inserts: Place the sandpaper face up over the trackwork, and holding the sheet firmly in place rub a suitable object over the top of the rails so that they are embossed through the paper. I used the rounded handle of a disposable knife to do this, but a coin would do just as well. It’s basically brass-rubbing for modellers. For sections where the rails are straight, it's best to move the now-embossed piece of sandpaper to a cutting board and use a steel ruler to produce a perfectly straight edge. Given the rough surface you'll be cutting and the thin backing paper's propensity to tear, make sure the ruler is positioned so that any slips or tears are on the outside of the insert. When working over curved rails or pointwork it's probably easiest to just cut the paper in situ using the inside of the rail as a cutting guide. The best way to do this is to make shallow cuts with just the tip of the blade, running it along the inside face of the rail just below its head, using the web as a guide. (I'll very happy to admit it: I'd never even heard these terms until I visited https://en.wikipedia.org/wiki/Rail_profile ) Don't cut deeply enough to hit the chairs or sleepers, or you won't get a smooth edge that fits snugly against the inside of the rail afterwards. Cutting through gritty, abrasive material does your knife blade no good at all. Change it frequently to avoid tearing the backing paper as it gets blunted. Actually, make that very frequently – I found one of those cheap tear-off-the-blunt-length-of-blade-with-pliers DIY knives is much more convenient for this work than a Stanley knife. Once the inserts are in place, push a wagon (ideally with the deepest flanges you can find) over the rails a few times to press down the inserts where they fit up against the rails. Very small blobs of blutack on the sleepers at strategic intervals will keep the inserts in place, while still allowing them to be easily removed for track repairs. Here's my first attempt, warts and all. And since all the materials cost me less than a pound, and the inserts are only held in place with Blutack, it'll be quick enough and cheap enough to do it all over again properly now I've had a bit of practice! I'm not sure any railway did have ballast this colour, so my next blog will describe my attempts to paint it a more realistic colour.

  2. Any industrial site needs oil drums and up to now I'd just had the one shape, made out of 35mm film pots which are the right size for 16mm. I decided I fancied doing one of the more corrugated designs which would make an interesting bit of variety. I modeled the shape up in CAD (nice wiggly line rotated) and then printed the drum out on the Wanhao D7. A coat of red oxide and it looks the part. At the same time I printed two different models of crows off the Thingyverse. Scaled to 16mm these are pretty damn small. I tried them in a couple of orientations and need to be a bit more careful with the support structure because the I broke the feed off one when I tried to remove it. I suspect if I want the legs modeled then I would better off using some fine wire. Not planning a 'murder of crows' yet. David

  3. I've posted a few updates on my Blue Pullman project over the last couple of years, but I really thought I ought to get my a*se in gear and finish the thing! One of the sticking points (other than the boredom and laziness instilled by a very repetitive, drawn-out project) was a lack of suitable decals, but on a recent ebay search I found that suitable British Rail style "Pullman" lettering was now obtainable, so over the last weekend or two I've cracked on with some of the jobs that were still to be done. These included: Adding bogies to the trailing power car Completing glazing of all units Completing interior work on all units Tackling some of the underframe differences between units General tweaking of couplings etc to ensure reliable running It's not all done yet! I've begun reworking the underframe details, but I'm taking if carefully one set of vehicles at a time, and so far I've only made a good start on the parlour firsts. I've also still to add the kitchen car roof detail, as well. Nonetheless I am very pleased with the look of the semi-finished article, and it''s a relief to find that the power car has no trouble shifting the complete rake. This is the undriven end. At the moment a couple of raw Tri-ang bodies are standing in for the parlour firsts, while I finish the painting of the intended shells. There's nothing wrong with these Tri-ang bodies as they stand, except that they don't allow for flush glazing (unlike the earlier livery models, where the window inserts were a separate moulding) so for that reason I'n repainting the earlier Nanking blue shells. The driven end. I won't add the decals until I've finished the testing of the rake, as I don't want to handle it excessively once the decals are on. Cheers, all.
