... And the check span is 41.7mm- 2.3mm= 39.4. Plus some freedom in the tolerancing= 39.5mm MAX. Then choose a flange curving allowance, for which I suggest 0.3mm. So that finally gives a minimum back-to-back of 39.5+ 0.3= 39.8mm. MIN. Summarising all that, I suggest: WHEELS: Wheel Width 5.5mm MIN. Flange Thickness 1.9mm MAX. Back-to-Flange: 41.7mm MAX. This is the most critical dimension. Back-to-Back: 39.8mm MIN. It is important to understand there is no maximum back-to-back dimension, the maximum wheel spacing on the axle is set by the Back-to-Flange dimension. For the best running aim to get as close to this as possible (without ever exceeding it), rather than the minimum back-to-back dimension. Taking the flange thickness up to the 1.9mm maximum would obviously require setting the minimum 39.8mm back-to-back to avoid exceeding the 41.7mm back-to-flange. TRACK: Track Gauge: ...

... slot in its place, but so far I haven't found anything suitable. Perhaps splitting out the Picture Shapes as an entirely separate function would be the best option. It may also be better to get the image visible first, say at A4 paper size as a default, and then do the scaling functions afterwards. regards, Martin. posted: 1 Aug 2007 21:05 from: Alan Turner Martin, I agree it would be better to split it out. I suggest a button under the file menu which said "import background image". This should import the image to the shape folder and then ask the questions to create the .bgs file. Whilst on the subject of background images could not the choice of having the grid lines in front of the image be put on the pad drop down with all the other choices for grids?

... sharp bend because of the 1:20 inclination of the rails. Instead, a short curve is used, as shown by the green line, making the knuckle gap wider than the flangeway gap. It works fine, and can help if replicated on the model. Some companies made this curve quite gentle and obvious as shown -- the NER for example. On the GWR the curve matches the crossing angle in feet, so for example a 1:7 crossing has the knuckle bend curved at 7ft radius. But it's important to get the flangeway gap correct alongside the nose of the vee at X in the diagram, otherwise there is a risk of wheels dropping into the gap in front of it. What you must not do is make the knuckle bend too sharp, as shown by the red line. This is guaranteed to cause problems. 2_050420_590000000.png regards, Martin. posted: 22 Nov 2015 22:26 from: DerekStuart Thanks Martin.

Regards Tony. posted: 28 Aug 2018 22:09 from: Martin Wynne Tony W wrote: In many ways, I still prefer the option to do things the long winded way and design things exactly how I wish. Hi Tony, Templot is a tool to use any way you wish. The detailed low-level options allow you to get things exactly the way you want them. The important thing is that you know you are opting to do it that way, in other words that you know other methods are available. Which was the point Andrew was making -- he was using the older methods only because he hadn't realised there were newer ones available. How to make sure all established users are aware of all the latest features, without annoying them, is a bit of a mystery to me. Don't forget that now Templot is open-source, you can go to an even lower level if you ...
... . regards, Martin. Thanks Martin, My daughter likes the music. Apparently it's on a Nintendo game called Cooking Mama. Well, about 10 minutes after going to bed last night I jumped up and said 'I've got it' and was told by the wife to write it down and do it in the morning. Anyway here's my version of the solution, inspired by John suggesting I use a tangent. It's not so elegant, but if you get it right you can have a symmetrical curve, but that is not important in my case. Sorry it's only a box file but it shows the sequence from top to bottom.

... can drag it anywhere on the pad, and there are some new functions in version 082d to arrange the labels neatly in rows or columns, move all the labels in one go, and turn them on or off quickly using the End key shortcut. The name label has 2 components, a number and a name. You can switch these components on or off independently. You can change the font, style, colour, etc., for the name labels (for the current session). The name labels are also important functionally to enable selection of individual templates using the Shift key, where several partial templates are overlaid. You can use a template name label as a general pad caption by adding a very short (say 0.1mm) length of isolated plain track as a dummy template. The current template doesn't have a name label but it does have a name, which can be entered via the information panel. 2. Background label shapes: Shown on screen pad: yes.

... / design point rodding posted: 3 Jan 2016 15:02 from: Simon Hartshorne Hello, I apologise if this is explored elsewhere- I did a search but couldn't find anything. I know that Templot is 'not' layout design software (although that is precisely what I have used it for- and I could not have done without it, it is excellent) but is there a way to draw (and then modifiy) point rodding/ cranks, etc? I have experimented with trying to draw it in Visio and import it, ditto DXF/DWG formats unsuccessfully. It doesn't need to be highly detailed and I can always resort to a pencil and draw it on a print out if it's not possible, just thought I'd check first....

... making much use of the open-source versions. Not before time, I have now in this 224a update got round to doing something about that. I have created a new MECBOX file format as a go-between to perform transfers between the versions. It is text-based, which means it is quite slow to save and load large files. But you need only transfer a file once, after which you can save it in BOX3 format for future working. MECBOX files are exported from one version of Templot and imported into another. After the transfer has taken place, the MECBOX file could be deleted, although it would be worth keeping as a backup. There is a new transfer menu in the storage box, with menu items to export a MECBOX file of your current box contents (track plan), or to import a MECBOX file if you wish: 2_301753_450000001.png There is also an option to export a matching MECBOX file every time you save a normal BOX file: 2_301753_440000000.png The above option is on by default and you probably want ...
... topic: 512 How low can you go- cheap PCs for Templot posted: 2 Aug 2008 23:40 from: Rextanka This is pretty off topic for most people, however I wanted to point something out for people on a budget who want a new PC. I just built a PC for home use for $350, not including Windows Vista Home Premium (another $114). Now all of this is in US money, but you can mail order it and pay the VAT/import duty, or get this stuff locally for a little more (because of the excessive UK VAT rate). The beauty (and curse) of technology is how, over time, it gets progressively cheaper. I was looking for the cheapest machine that would run vista and ubuntu linux, and still be capable of running things like templot, the 6 year old copy of Matlab student edition that I have, and some TI software for programming microcontrollers, whilst still having enough juice to do some programming under both vista and Linux. Intel just released a ...

One important point. It's essential to tell the printing firm to set "No page scaling" in the printer dialog. This is not the usual default setting, so you need to emphasize this point. Tell the operator at least 3 times.

Martin. posted: 31 Aug 2016 11:56 from: Stephen Freeman Hi, I forgot there was an intermediate screen- still have the problem though when I look at the DXF file, everything is much larger than I would expect but that's probably just my unfamiliarity with Double Cad posted: 31 Aug 2016 12:40 from: Martin Wynne Hi Stephen, I'm not clear what you mean by an "intermediate screen"? There isn't any other. Most sizing problems importing DXF files are caused by getting the units wrong. Remember that DXF files do not include any units information. That's why Templot puts in or mm in the file name. Before importing the file, select DXF in the file type and then click the Settings/Setup/Options button. Set the units to match the file.

... . However one thing I did note was, you should leave the originally set alignment curves (or straights) in position on the workpad overlaying the diamond, so that you can use them to align and position the four (4) switch blades required by the slip, these can be removed later once the blades are in the correct required positions. The first thing is to save your switch blade template which can be used for all four slip switches. Next copy the switch blade template to the control. Now it is important to know which way to add the switch blades, as a guide, please see Figure 3 image below, which explains the meaning of< facing – facing> and< facing – trailing> mentioned in the menus. Please also note that these terms are referenced to the peg datum position of the curves (or straights) track, and not the joint end of the track. You now need to add the switch to one of the curves (or straights), do the following, Select< geometry>< ...
... . At this stage the rail at 3 will be wrong (too close to the stock rail). Remove it and make a small bend at the end of the planing (2 in the diagram), so that when clipped back in place, the rail at 3 is correctly aligned. You can check this using track gauges from the opposite stock rail. Repeat trial and error as necessary. When you are happy with the fit, you can start filing the front of the bade. Getting this right is not as important as the back of it. Remove the bulk of the metal first, then for the final filing you could perhaps do it in place on the above filing aid if you clamp the rail down at 3. To that end it would be good to make the filing aid on a piece of board which can be held vertically in the vice. Use the file at an angle, with the safe edge at the bottom to leave the rail foot intact, and file until the the blade tip is a knife edge at ...
... topic: 2669 Brunel blues, 7mm broad gauge problems posted: 5 Apr 2015 09:59 from: keithj15 Fellow club members have started an O gauge Broad Gauge project, and asked me to draw up their track plan. Having gathered together all the track stats from the Broad Gauge Society, and created a custom gauge, all looked good until I tried to create a regular crossover. I then found the turnouts overlap and the all important V's don't generate on the template. I have tried all the variations of the turnout geometry, but have concluded that there must be some simple parameter that I have missed — possibly in the custom template dialogues, and this screws up the correct creation of the regular crossing — and maybe other configurations of turnout and crossing templates yet to be encountered. Can anyone help point out what I am missing? I have attached a box file showing the problem. regards Keith Johnson Attachment: attach_2102_2669_7mm_Broad_Gauge.b ox 234 posted: 5 Apr 2015 10:14 from: Alan Turner Widen the track centres using Geometry/Adjacent Track ...

... What a fascinating document: http://www.ordnancesurvey.co.uk/docs/support/guide-coordinate-systems-great-britain.pdf And why am I reading it you ask? Well I'm entertaining the notion that Templot might add GPX files to its existing range of file exports. At present it is possible to use OS maps as a background guide to track planning. If we had a GPX export we could work the opposite way by adding Templot track plans to the original maps. There are many mobile apps and programs which will import GPX routes and draw them over a map such as Google Maps. This means that having created our fictional branch line to wherever, we could physically visit the site, and using a handheld GPS device, chalk out in the car park where the bay platform will be. If we do this on Christmas Day, we are likely to have the streets and car parks to ourselves, and be able to climb over a fence and hammer sticks into a lawn to mark the position of the cattle dock. Nowadays many folks ...
... left to right can hit the nose of the vee and very likely derail, or at least bump. If this dimension is too large, the wheel backs will bind or jam on the check rail. To make sure it's correct, the check rail is set using check gauge tools. For 00-SF and 00-BF this dimension should be 15.2mm. You can use the same check gauge tools for both these standards (they are both running the same wheels). B is the crossing flangeway gap. It's also important. If this dimension is too small, the wheel backs will bind or jam on the wing rail. If this dimension is too large, the gap in front of the nose of the vee will be too wide, and the wheels may drop into it with a bump. This gap is set using a small piece of metal shim called a crossing flangeway gauge shim. For 00-SF it should be 1.0mm thick. For 00-BF it should be 1.3mm thick. C is the track gauge. It shouldn't ...
... , so pretty old wheel specs. posted: 10 Sep 2019 14:32 from: Martin Wynne Narrow-gauge modellers often use the wheels and track standards from a smaller scale. For example 009 models at 4mm/ft typically use N gauge wheels. It defies logic to build a model where the wheels are to a different scale from the rest of the model, but it is a popular way to build a working narrow-gauge layout. Until that is, you want to build mixed-gauge pointwork. The important point to bear in mind for mixed-gauge track is that both gauges must use the same flangeway gap, and therefore need the same or similar wheel profile. For 00 RTR models, the practical minimum flangeway gap is 1.0mm (as 00-SF). But N gauge wheels require a flangeway gap of 0.85mm max. If they are run over crossings (frogs) having a 1.0mm gap they are going to fall into the crossings with a bump -- made worse by the small diameter of such wheels. If ...

... on your track plan, and written an initial first list of the issues and the remedial action I took to correct them, this is in the form of a PDF document which is attached to the next message. Please do not be put of with the somewhat drawn out content of the synopsis and action list, as I have stated every little baby step of the corrective actions, so that you can get a better idea of how to use them to correctly align track-work and get better flowing track. It is important to understand that this is my method of working with which I am most comfortable and would most likely be used by most others, but others in the Templot Club may have slightly different ways of doing the same functions, however, I can say it will work very satisfactorily and achieve good layout results. But at the end of the day, so to speak, it is what you would be comfortable with in working with Templot. Simon, this is only Part 1 of a synopsis of how to correct and align ...
... if you would like to try it. (Pug= Pilot UpGrade) It's now several months since 091a, which was the first version using the later compiler. 091a has proved to be stable, so this new version 091b has reverted to installing in your C:TEMPLOT folder, so using your existing launch shortcuts and replacing your previous Templot version there. (091a installed in its own C:TEMPLOT_PUG_09 folder.) However, it's still a change of compiler from 082d and earlier, so please make backup copies of your important Templot data files before overwriting them using 091b. Here's the download link: http://www.templot.com/tug/templot_pug_091c_setup.exe [revised for 091c] What's new in 091b? Here's a brief list. I will update the web site with more details shortly: Multiple monitors are now supported. There is an extra dialog during startup with more information if you have multiple monitors available on your system. For best results arrange the primary monitor to be on the left.
