... nose of the V-crossing (called the "lead length") can be changed. This is sometimes done in order to fit a turnout in a given space without changing the switch size or crossing angle. The lead length can be shortened (at the expense of a sharper radius) by increasing the length of the crossing entry straight on a regular-type V-crossing. This may at first seem counter-intuitive, but try it and see -- here's an old bit of video showing the effect of adjusting the length of entry straight (SHIFT+ F11 mouse action). Note that there is no change to the switch size or crossing angle: Allow time for the video to download: Or to lengthen the lead length it is necessary to reduce the entry straight to zero (i.e. generic-type V-crossing). If that's not enough, further lengthening would require changing to a longer switch. regards, Martin. posted: 25 Oct 2016 15:11 from: Stephen Freeman Yes I know, but I ...

Use the dummy vehicle tool to check (as above). cheers, Martin. posted: 5 Apr 2019 15:44 from: wcampbell23 Hi again Just noticed something else that may give you problems. The turnout leading to the inner fiddle yard loops has a very tight minimum radius. As it stands it is a left-hand turnout- re-draw the inner track as a constant radius and then insert a right-hand turnout in place of the LH. Adjust the angle of the V to give a smooth alignment into the second loop. Regards. Bill. posted: 5 Apr 2019 17:11 from: Alan Kettlewell Many thanks for the comments. Well spotted about the big curve being too close, I hadnt noticed it had changed since I did it as it wasn't tight like that. I reckon I must have changed it while tinkering about at the other end of the curves. I'll have a closer look at platform widths and clearances generally and another go at the diamond ...

... does it very well). Perhaps if you could explain where you get stuck we can help, and perhaps relieve some of the load from Martin Don't take this the wrong way, but are you spending an hour a night on the tutorials or an hour every six months? I'm the last person who normally uses tutorials, but when I dived straight into Templot I ground to a halt because, like most people it seems, I was expecting a CAD/Windows type package. The tutorials really did help to re-adjust my mindset and make me understand the way the software works. Most of it seems second nature now, but I'm still finding new things and there are still things I'm aware of being there but don't really understand what they do! -- Paul Boyd [url http://www.paul-boyd.co.uk/ [/ url] posted: posted: 16 May 2007 21:12 from: Bob Ellis Hi Paul, What I would like to achieve in the first instance is to produce a track plan for the P4 test ...

... maths that was necessary Jim. posted: 19 Dec 2009 20:46 from: wcampbell23 Hi Raymond The concept is certainly feasible. The critical bit is to make the curved top (so to speak) at each of the six tracks the SAME radius and each with its own centre point- not concentric- so that the angle that each track meets the entrance road at the same angle. The wagon storage tracks at the top are a little trickier since they must also have the same radius and so, unless they are adjusted after the point of contact, they will converge on each other towards the top of the plan. It would be a good idea to use a wider than normal track centre spacing to avoid problems with the curved traverser tracks converging. Otherwise- it should work fine. Regards Bill. posted: 19 Dec 2009 21:06 from: Martin Wynne Hi Raymond, As Bill says, it should work fine -- providing you create the traverser tracks using the shift functions and not the double-track functions. You may ...

... topic: 1134 MSL/GCR 1 in 8 Through Crossing posted: 28 May 2010 22:27 from: Bill Fay I have gradually been teaching myself Templot and learning something of track geometry but now I am stumped. Some while ago I obtained from Tony West (GCRS Model Steward) a copy of an 1895 drawing of an MS&L 1 in 8 through crossing. I scanned this (Unfortunately two pages with no overlap) into Templot and adjusted the size and twist to match the basics to a Temploted 1:8 crossing. I have got this as near to correct as I can. It is obvious that there are imperfections in the drawing, partly due to photocopying (probably a number of times) and also inaccuracies in the drawing itself. My first problem is that the 2 crossing fine points and the center of the crossover should line up by the basic laws of geometry, unless I am missing something. For the moment I have put this problem to one side and concentrated on the turnout. Ignoring the sleepers, wing ...

... X.XXT-XH" templates rather than background templates in the storage box. The advantages in being that it's quicker to get at the parking bay than trawl though the storage box. When I get time I'll amend the instructions accordingly. posted: 30 Apr 2010 20:08 from: richard_t As promised an updated version of a irregular diamond help/walk through. The method has changed (uses the parking bay, a feature I should use more), but the outcome is the same. There is also a note about adjusting the templates when the diamond lies within a transation (probably also applies to a slew as well).

... 105_051651_160000001.png The guide templates will eventually get wiped (not deleted) as they start getting in the way. The key point of doing things this way is that when you copy from the guide template, it doesn't matter which section of it you use, any partial templates will always have the same curvature so that the whole formation will flow- in the above screenshot, none of the roads through either diamond are straight. Likewise, if you insert a turnout, the through road will always follow the guide template and you can adjust the crossing angle and position (by roaming) until the turnout road lines up with one of the other guide templates. It strikes me that there ought to be a more detailed guide on all this! Perhaps I'll get around to doing one soon, but not until the Easter week visitations are over with Hopefully this will give you something to be going on with though.

... Vee? And a second question; I have seen a method which initially appeals to me of using soldered rivets say every fourth/fifth sleeper with plastic cosmetic chairs in between. Has anyone had experience of this method? Derek posted: 11 Mar 2010 14:42 from: polybear Norman Solomon puts the stock rail in first.... HTH Brian posted: 11 Mar 2010 15:06 from: allanferguson I had always been a dyed in the wool rivets and solder man, and it is undoubtedly strong and easily adjustable. However it undoubtedly the most mind numbingly tedious job I know to mark, punch, and rivet up all the sleepers. (As a Scottish pre- group modeller I use sleepered leads). Of late I have taken to functional plastic sleepers, in my case from C& L, and I have developed confidence in the method. Using the recommended Butanone solvent I have attached plastic chairs to ply sleepers, and have never had any come undone. In extremis I can with a craft knife carefully peel the chairs ...

... put it in because of the usual 'elf n safety' stuff. It is planned to put one in at Harmans Cross at some stage. I'm impressed that Paul Matthews managed to find a dry day last summer! The plan imposed on a satellite image is brilliant. Phil posted: 16 Feb 2010 18:34 from: Paul Boyd I'm flattered- thank you all for your kind comments! I superimposed the satellite image to get the scale- just off the bottom of the screenshot is a 50ft scale marker, so I adjusted the image over the map in Photoshop until I got the best alignment, then used the 50ft mark with a 200mm grid in Templot to get the scale. The Templot bit isn't perfect, and subsequently looking at a photo of the left hand end (as in the screenshot) shows that the turnout is probably something more like 1:8 or 1:10 with a distinct S-bend to the other platform line. Still, it only took a few hours with just the satellite image and map to work from ...

... how these servos work. Holding the input at a constant high or low level should not make the slightest difference. In either case the servo will not receive any stimulus to change its position. It is essentially "off". The reason holding it high rather than low might make a difference is because the noise immunity of the input in the low state is really lousy as opposed to merely "not very good" in the high state, but in either case, if noise does mange to trigger the servo it will adjust to an indeterminate position and because there are no subsequent "real" drive pulses, it will remain at that indeterminate position.
