Hi Martin, It might be me of course, or my computer but I've just been doing some 009 turnouts, pretty sharp radius I know but there seems to be a problem with the Y turnout. Have I done something wrong or is there a flaw? Stephen |

Hi Stephen, You have gone below what Templot can reasonably be expected to draw as a single template.  For such an extreme turnout you really need to build it up from partial templates for each rail. Your crossing angle of 1:1.8 is shorter than the usual limit for turnouts (1:2) and your curving radius of 102mm is only about 11 times the track gauge. Does any stock actually run round such a sharp curve? Or are you aiming for something like Gn15  -- see:attachment.php?id=177 gn15_1.png  You can improve matters a little: 1. reduce the step size -- program > expert > step size... menu item. Try setting 1.0 mm. 2. shorten the vee rails so that the turnout ends just beyond the crossing (as images above). But building it from partial templates is the best solution. regards, Martin. |

Thanks, thought it'd be something like that, I think any stock would be restricted to very short wheelbases (minitrix hoppers?), I did dabble with 009/HOe some years ago and found that not everything would go round/through the Peco turnouts then available. | ||
