I've been tinkering around with different design ideas mentally of late and wanted to try something out. I then decided to commit fingers to keyboard and chose 00-BF because, at the time, I was a little concerned that the radius of some of the curves may be a shade too tight for 00-SF (and, anyway, this was the fiddle yard). Once the fiddle yard was sortd my attention turned to the scenic part of the layout where the curves are generally far more generous. However, I left the gauge at 00-BF. With the layout plan compete I thought I'd do the right thing and change everything to 00-SF, none of the curves ended up tighter than third radius. I group selected all templates and changed the gauge of all the templates (or so I thought - although I did wonder why one template became misplaced). I then noticed that one of the turnouts was still 00-BF. I changed the gauge of this and the resultant turnout was quite a bit shorter than to original. This will be quite beneficial as far as train length is concermed so I'm quite pleased. Why is there such a difference in turnout length between the two gauges? Could I just build the track with 00-SF gauges using the 00-BF templates as they are? |

Not really recommended, and it's easy with Templot to print the right template so why not do that?  You can't do this for diamond-crossings and slips. For these it is essential that the template is drawn to exactly the same track gauge as the gauge tools which you will be using. Otherwise it will be impossible to align the rails correctly. For this reason it is important to check the printer calibration before printing templates for diamonds and slips. The length of a template is dependent on the track gauge. 00-SF track gauge (16.2mm) is smaller than 00-BF (16.5mm), and consequently the 00-SF templates are slightly shorter. I'm a bit puzzled that you say one template is significantly shorter after changing from 00-BF to 00-SF. Can you attach the .box file showing this? Thanks. regards, Martin. |

Martin My fault. On closer examination the point in question this morning was one that had beem extended at both ends and when the gauge was changed it returned to normal length. My only reason for asking about using the OO-BF templates was laziness - not wanting to have to convert each one individually to OO-SF. On reflection I'm probably best advised to use what I have as a base and start from scratch as I've seen ways that the slightly shorter lengths of the turnouts can actually improve the track layout. However, before I do so, I recall you making a comment about the advisable minimum radius for OO-SF pointwork. Many of the points in my fiddle yard need to be around 3rd radius (i.e. 20"). Am I best to stick with OO-BF here and use the finer gauge on the scenic section? Apologes once again for the false alarm. Ray |

Select 00-SF in the list. Click the convert group button above the list. Bear in mind that the gauge/scale ratio is changing slightly, so you may find some gaps or overlaps between the converted templates which need tidying up. Many of the points in my fiddle yard need to be around 3rd radius (i.e. 20"). Am I best to stick with 00-BF here and use the finer gauge on the scenic section?Yes. 00-SF is a variant of EM and not really suited for such tight curves. You can get it to work with appropriate gauge-widening, but for a fiddle yard you may as well use the wider 00-BF dimensions. That radius is still very tight. You may find that you can ease the radius by changing to straight switches instead of the REA switches, or by making other similar changes in Templot. regards, Martin. |
