Can you advise where to look in the tutorial for help with creating a curved crossover, outside curve with a centre line radius 2101mm. I am working 7mm finescale. Thanks Alan Dale |

Don't know if I'm missing something here, don't you just curve the first turnout to the radius you want then do tools / make simple crossover? cheers Nigel |

A radius of 2101mm (where did the odd 1mm come from, Alan?  ) is quite sharp for finescale 7mm. So before making the crossover you would need to check the adjacent track spacing for the turnout side (TS). I would suggest increasing it by say a foot from 6ft way equivalent, to 7ft way equivalent, to ensure adequate running clearances.Then you need to consider the size of the turnout to keep the minimum radius sensible. Probably that requires at least a C10, and maybe longer. Finally, for a curved crossover in running lines the timbering would normally be square-on instead of equalized (skewed) to give maximum resistance to gauge spread. After all that you are ready to make your crossover. But you are still not finished, because the long timbers will need shoving across both roads. Alan asked for a tutorial for all that, and there isn't one specifically for curved crossovers.  I will do a video shortly, Alan. In the meantime, this video is a good beginner's guide to the basic Templot methods and includes making a curved crossover:overlaid tracks on a rough sketch Also the static "track plan" tutorial shows a curved crossover being made, starting at screen 7 to screen 14. regards, Martin. |

Hi Martin I have spent the weekend trying to absorb the tutorials and have now created and printed on A3 the crossover by creating a rh point and then following templot help info crossover with curved crossings and track centre line spacing at 80mm. Could I mail you the track plan for you to check | ||

I'm a bit puzzled by your statement that you are using curved crossings. Crossovers are normally created using regular or generic types of V-crossings.  regards, Martin. |

Hi Alan,This week I have created a 7mm Finescale RH Point 2100 rad 1.9 C Generic. Adjacent track 87mm centre line spacing. Shorten turnout F4, Moved the fixing peg onto the TXP Point, Stored it to background, then rotate 178 degree could not do 180 absolute then went to curving and set rad -2100 and printed it out on A3 it look OK. What do you think? I don't understand why you are doing all that when Templot will do it all for you? Just click the tools > make crossover menu item as Nigel explained. Watch it happen at: http://www.templot.com/martweb/videos/flash/starter/em_starter.html You have made a mistake with the radius. If the outer turnout is on 2100mm radius, and the track centres are 87mm apart, the inner turnout will be on a radius of -2013mm (negative radius for the contraflexure).i.e. 87 - 2100 = -2013 But as I said, Templot does all this for you. I am making you a video with some additional notes, but it's taking a few days. In the meantime please watch the one on the above web link. regards, Martin. |

Hi Alan, Thanks for your private message about this. I am currently preparing a video showing your crossover being created, and I will post a message about it here when it's ready. Please note that as you have a demon.co.uk email address, you will not be receiving emails from Templot Club at present. This applies to everyone with a demon.co.uk email address or a domain hosted by Demon. For reasons best known to them, Demon are currently blocking emails from this email server. This means that Demon are blocking your genuine emails and probably not telling you. More information at: http://www.demon.net/Scripts/fp.do The easiest solution is to receive the Templot Club emails via the Yahoo group instead. However, that won't apply for notifications about replies and private messages. (Comcast have now lifted the block following intervention from my provider.) regards, Martin. |
