Here's the Banff station pilot (on loan from the Eastfield depot ) on the treadmill. Borrowing a page from gordon s, it's getting at least 15 minutes (sometimes I forget) in forward and reverse at half- and full-speed. ... and here's the external DCC controller. I wire the DCC bus across baseboard joins using EC3 connectors, so it was just a matter of making a DCC-to-DC adaptor, and plugging it in between the board and the controller. Easy-peasy, except that I did it wrong the first time - which is why multimeters were invented .

aardvark Posted April 1, 2021 Author Share Posted April 1, 2021 (edited) As dull as photos of locos on a rolling road are, I’ve decided to chance another one, hoping it might be of interest. It’s a Replica Railways powered chassis. I understand some use these in DMU’s and EMU’s (no, not the bird), but in my case it will (one day) go into one of my 57’ non-corridor coaches to model gravity shunting. Interesting engineering: two motors drive all four axles, and it’s DCC-ready. I can’t speak highly enough of their customer service.

aardvark Posted May 13, 2021 Author Share Posted May 13, 2021 Progress is slow at chez Aardvark, but that's nothing new. Nevertheless, progress there is. This morning, I have a servo that waggles* a turnout backwards and forwards - this baseboard only has the one turnout to control. The technically allergic should avert their eyes from the following paragraph. I’ve gone with a servo on MERG mounts, driven by an Arduino R3 through a PCA9685 PWM driver card. I’ve written a small program (Arduino calls it a sketch, but it’s a program to me) that allows me to exercise the servo from the laptop keyboard to determine the required servo values for both turnout normal and reverse positions. Lots yet to do: Write an accessory decoder program to control the turnout from my DCC controller. Install a DC bus to power the electronics from an ex-laptop power supply (2-wires becomes 4), as I'd rather reserve my limited DCC power for things like locos that absolutely have to have it. Respect for all those that tackle such activities upside-down beneath fixed baseboards. Being able to stand my baseboards vertical as in the photo is a definite blessing. * technical term. 6 Link to post Share on other sites More sharing options...
aardvark Posted June 17, 2021 Author Share Posted June 17, 2021 (edited) The turnout on the board shown above is now functioning from my DCC control, and the second board with 6 turnouts is progressing well. The hold-up is some nuts and bolts to mount the electronics under the boards. In the meantime, my thoughts turn to “What’s next?”, and I think the answer is “buildings”. In the first phase, I’m talking about the station building, signal box, goods shed, engine shed, water tower and Scotstoun cottages. Other buildings may follow later. This is all new to me, so I’m making it up as I go along. (Anybody with experience is welcome to chime in.) The following is my plan: it’s good to have a plan, as at least you know where you’re deviating from it. I’ve never been much good with colours, so I’m inclined to avoid the more exacting painting scenarios (and associated expletive usage) by using “brick” papers where appropriate. I think I’m talking about things like brick and stone walls. “Brick” paper buildings: station building, engine shed, water tower bottom, Scotstoun cottages. Plasticard buildings: signal box, goods shed, water tower top. I’m inclined to start with the cottages, being smaller without being fiddly, and lesser detailed. Someone smart said that you should start with a building’s windows, and here starts one of my difficulties. I’m probably being overly pedantic, myopic, or simply wrong, but I struggle to find decent candidate model windows. For instance, take the main engine shed windows, 3x6 panes which I estimate to be 3’ x 6’6”. Allowing, say, 3” for top and side frames, 6” for bottom frames and 1” for muntins, this would leave a pane size of roughly 9.3” x 10.6”, or, in OO scale, 3.1 x 3.5mm. It would seem that I might need to build the windows myself, which is, I suppose, what scratch building is all about. Old-school built theirs from acetate sheet and address labels, while Paul Bason’s Scratch-Built Buildings advocates plastistrip frames and glazing beads drawn in paint. I must admit to being tempted by the purchase of Silhouette cutter, attracted by the possibility of neater windows than I might achieve by hand. There's threads on RMWeb detailing the trials and tribulations of their use in cutting plasticard.

You don't get the relief that you do with a proper moulding but it works for me at the proverbial normal viewing distance. 1 Link to post Share on other sites More sharing options...

It might be worth looking at Tichy Trains stuff, here: https://www.tichytraingroup.com/Home.aspx Perhaps best to start with the catalogue, rather than the online shop. One difficulty is that the openings are given as decimal inches, not millimetres, so it isn’t straightforward to see if they do something suitable. However, I did use some of their products quite a long time ago and they are very fine mouldings. They do some assortment packs as well, which basically give you a sample of the various window mouldings they produce, or that’s what it was when I got them years ago. I think mine came from Micromark.com, as I ordered some tools from them at the same time. I did though later order some specific mouldings and kits from Tichy. At the time both delivered to the UK, but don’t know if they still overseas (they are both USA companies). There is/was another supplier of plastic window mouldings in the uk, but their name escapes me just now. Hope some of this helps! 1 Link to post Share on other sites More sharing options...

None of these names was new to me, yet I've found two possible candidates for the engine shed windows in the Tichy range - so that has raised the Hopefulness Coefficient significantly. In hindsight, I may have been guilty of bouncing around like a pingpong ball in a tumble dryer, jettisoning one unsuccessful search to fit one particular window for a search for a different window, all without positive result. I may also have been dissuaded from a decent search of Tichy by their units, and certainly didn't look in their catalogue.

Here's the underside of board #4 which has 6 turnouts. The heavy horizontal wires through the middle are the DCC bus, while those at the bottom/back are the DC accessory supply, so four wires instead of two.

aardvark Posted August 7, 2021 Author Share Posted August 7, 2021 (edited) Today, after the memsahib departed, Aardvark took possession of the garage and setup the layout for a running session, with the intention of proving that the frogs had been correctly wired by the technical crew. We had one operator in attendance, and despite the poor turn-out, did prove correct functioning of all turnouts, thereby avoiding punishment of the long-suffering staff. The pictures don't really add much, except please note the cunningly crafted "urban detritus" backscene. The long-awaited Tillynaught-Banff express arrives (backwards) at Banff at 14:21.

aardvark Posted August 26, 2021 Author Share Posted August 26, 2021 (edited) Surprisingly, and perhaps uncharacteristically, I may have done some actual modelling. I bought some 5x2x1.7mm neodymium magnets, which I used to hold the RES03 window parts while laminating. The parts are held together with the magnets, then tacked with a spot of glue and weighed. Later, the parts are glued all round and again weighted. I think that the after close-up shows a good result.

aardvark Posted September 3, 2021 Author Share Posted September 3, 2021 (edited) Aww - gee - 3 people gave me a "craftmanship/clever" for the previous post - I am taken aback In the meantime, lockdown is beginning to bite and I feel the need to communicate with someone other than my wife and the postie. I had my boards out recently, and decided that I was sick of looking at the copperclad sleepers at the baseboard joins. So I fished out my little pots of paint and an equally little paintbrush. Now, I did this with some trepidation, as I don't think I've ever painted anything smaller than a bedroom wall, but the results were unexpectedly pleasing and give me an excuse to attempt communication. Based on this success, I'm eyeing the areas beside the tracks (which probably have a name), and have started thinking about doing something to them, which might actually result in this looking like a model train set layout. "Started thinking" - no need to rush - this is lockdown, after all. However, nothing's ever easy, is it? Turns out the base colour in the little pot is darker than the supposedly identical paint in the spray-can. And while I was there, I discovered my small collection of RailMatch paints, which I bought while in the UK in 2015, have settled (who would have thought?), so a stirring session in the garage will follow. I might try storing the little pots of paint in the drawer underneath the washing machine. Alternately, a friend recommends inverting full-sized tins of paint on a monthly basis to avoid settling.
