... topic: 3037 Dual gauge turnouts posted: 7 Jun 2017 16:48 from: George Ray Several years ago I produced some dual gauge turnout 5" and 7 1/4" templates for our local Model Engineering Society of which I am a member. The requirement has now arisen to produce some more bespoke turnouts. I still have the original box file but the difference is such that I think I really need to start again. I started with a 7 1/4" turnout then tried to align a 5" gauge turnout on top to start to develop the necessary partial templates. However I can't find the notch and peg positions that allow the main rail to be common for both turnouts. Help please. I also need to be able for the turnout side rail to be the common rail for another turnout. The original templates were produced on v91c but I dont think this should have made a difference I just have forgotten how I did it.Any help gratefully received. posted: 7 Jun 2017 19:38 from: Martin Wynne Hi ...

... topic: 1084 GW tandem turnout posted: 22 Mar 2010 12:06 from: Phil O Hi All Does anyone have any info on how the GW would have arranged the timbers under a tandem turnout? I have had a look in David Smiths book GWR Switch& Crossing practice and can find no help there. Below is the turnout which I would like to sort out the timbers. 38_220704_280000000.png TIA Phil Last edited on 22 Mar 2010 12:08 by Phil O posted: 23 Mar 2010 21:26 from: Paul Boyd Tricky question! This is the way I do it, which may be right or wrong. I work on the basis that each element of the turnout is made up of standard components, i.e., three crossings and two switches. On the prototype, the timber spacing within each component was pretty much fixed so that the special chairs would fit so that's what you have to base the overall timbering on. So, starting with the switches, you know what type of switch you're using and where the rail joint ...

Hi Richard, What you have there is the makings of a 3-throw turnout, with both switches coincident. 3-throw turnouts are quite rare on the prototype and only used in yards and sidings. A 3-throw turnout would not be used in a passenger running line as you have it there. What you need is a tandem turnout, in which the two base turnouts are staggered: 00_tandem_quick.png Have a look at the one Tony has just done for Brian to see the difference: topic 2053- message 13667 Tandem turnouts have been much discussed on here.

But for clockwork, battery, or live steam? posted: 17 Jun 2016 15:43 from: Hayfield Paul I agree with you about the gaps in copperclad, but I offered to build one turnout just for the experience of building one. One thing I have done is to gap the sleepers before I start soldering, and then fill the gaps with filler and sand it flat, as its so much easier to do this without any rails in the way. You can also test the work whilst building it under power I also sometimes use the odd copperclad timber in a chaired turnout, using a packing piece of 0.6 mm double sided copperclad strip (this insulates the rail from the timber providing cast chairs are not used ...

... 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 ...

... will hold the rail firmly to the sleepers and timbers, and allow for expansion and contraction. Common and obtuse crossings can either be made as self contained units on 0.5 mm shim or copperclad. Or if prefered use copperclad sleepers where the crossing is, use shim or thin copperclad strip to raise the rails, some may feel this is an easier construction method. Once soldered in place grind the material back to the rail sides to allow the fitting of half chairs Who needs 1 mm check rail chairs for 00sf or EM gauge turnouts and crossings. In P4 they are a pain to thread, its far easier to cut a half chair off and fit the check rail using a check rail gauge. I will post a couple of photos which will explain the method. Sorry for those who prefer more traditional methods of turnout construction and feel I may be having a go at their methods, but the C&L/ Exactoscale and Peco plastic chairs have proved themselves now for over 30 years. Just use the correct solvents. Word of caution over the ...

... topic: 1889 Three-Throw Turnout (not tandem) posted: 28 Mar 2012 09:14 from: mike47j I'm drawing a layout in 0 gauge, based on Greenwich Park (about 1900). There is a run round line between the platforms which needs a three-throw turnout. I can follow the tandem turnout for the central frog, but I'm not sure what to do at the toe end. In the image gallery is a drawing of a Great Central three-throw which shows the centre blades are 3ft longer than the outer blades. Due to the lack of space the other end of the crossovers will probably need to be 9ft curved 1:6, do I just start with a 12ft curved 1:6 for the three-throw? And do I have to do anything special at the heel end? Thanks Mike Johnson posted: 28 Mar 2012 16:35 from: Alan Turner To my knowledge Three Throw turnouts were not used in running lines. However the principle is that each pair of switch blades has a ...

... out some point work. Mainly an outside slip with a diamond attatched to it. Could someone point me in the right direction to making this possible... Hopefully the file will be attatched to this post so you can see what i mean. Many thanks Andy Attachment: attach_1337_1813_Herstmonceux.box 318 posted: 29 Jan 2012 20:41 from: Alan McMillan Hi Andy I've run something up for you. An outside slip was never going to work in that tight space, so I took the liberty of replacing it with a single turnout and a double switched diamond slip. I also eased the curve to make it less like it hand been built using Peco Setrack. The start and end points are, however, the same except for the siding that comes off the slip. I haven't done any timber shoving though. Regards Alan Attachment: attach_1340_1813_Herstmonceux.box 324 posted: 29 Jan 2012 21:34 from: Stephen Freeman AndyJ wrote: Hi there...

... inner face of the crossing wing-rail. Thanks for your very helpful reply. I had held off printing the templates until I received a reply and, just as I finished printing, in came your post. Thanks for your comments regarding the wallpaper. I think I shall abandon the this approach for the reason you have given and because of the issues I have found with flatness and vulnerability. I guess I am going back to the traditional cork sheets instead. Your comments about the templates are a worry. When building turnouts with copperclad I was able to remove the templates on completion of the build before fitting them to the baseboard. Ballasting was no problem.I have found though that the ply sleeper and chair method of construction does not produce the same same degree of stability when the templates are removed and distortion can easily be introduced. I am using balsa cement to secure the sleepers to the template and Butanone to secure the chairs to the sleepers. Is there a real problem ballasting with the templates in place? If so, is there a better ...

Last bit needed before I have to go back over the layout and go through sleepers. Attachment: attach_2531_3107_conwy.zip 216 posted: 13 Oct 2017 11:50 from: John Palmer I would do it by making TL533 the control template, then making the crossover by using Tools -> make ordinary crossover. Before doing this, however, you need to adjust the turnout side adjacent track centre for TL533 so that the crossover thus formed aligns with the adjacent down main line (PR477). Because TL533 and PR477 aren't running parallel here, you will need to pick an arbitrary point on PR477 at which to measure its current offset from TL533 then make some adjustments after the crossover is created.2129_130634_140000000.png As the image shows, I picked a point on TL533 lying opposite the expected mid point of the crossover, slid the peg to this ...
