Hi All, does anyone know a source of 0-FS track gauges? Results from google are somewhat confusing as to exactly what is being offered! Cheers Richard |

If 0-FS is normal finescale 32mm Richard, then C+L sell them. We also sell the finer scale alternative - 0-XF - 31.0mm. There is another scale 0-SF, which is 31.2mm. I know of nobody who sells them, (although there well may be), and we have no plans to produce such a gauge. Regards Brian Lewis Carrs - - C+L Finescale . |

BeamEnds wroteOoops - I meant 0-SF! If I got some made, would there be any interest? Hi Richard, There would probably be lots of interest. The 4mm 00-SF group have been down the same route, and thanks to the good work of members now have an assured supply of excellent gauge tools. You might like to contact Brian Tully at stores at 00-SF.org.uk to discuss manufacturers, or see discussions at: http://groups.yahoo.com/group/00-SF (Drawings in that group's Files section.) regards, Martin. |

Clearly every modeller must do what he thinks best, but personally I see no need for 0-SF. If normal F7 finescale and/or S7 is not for you, then 0-XF is the logical choice. It looks good and runs well - can you ask for more from trackwork? (Now, just wait for young Wynne's reply.....). Regards Brian Lewis Carrs - - C+L Finescale . |

Brian Lewis wrote:(Now, just wait for young Wynne's reply.....).Hi Brian, My reply is the same as yours: "Clearly every modeller must do what he thinks best".  We've been over this subject several times, so I don't think I have anything to add to what I said before. See: previous 0-XF / 0-SF topic . regards, Martin. |

Peronally I prefer the three point track gauge, especially on curves - it lets you open up the gauge slightly on a curve which always helps with the tight curves that we use on models. On a six foot radius I end up with about 32.1mm face to face. Four foot radius (which I only use on a few industrial sidings) gives almost 32.2mm and, of course, 32.0mm on tangent track. However, I know that I am in a minority on this; most people seem to prefer the roller type gauges. I do use the roller type gauges on tangent track and points. Glen |

Ok - the track gauges mentioned are pretty similar to the 0-FS ones I already have, so..... Is there a definitive spec for 0-SF (tolerances etc) - I think it would be best to be able to point to somewhere and say that's where I got the info from, to avoid, er, "debates"! Rail - it looks like Peco for flat bottom rail simply on ease of obtaining it (relatively speaking of course), but what would be the "best" spec for bullhead for 0-SF? The three point gauges..... I presume (never used one, so I'm guessing) that the point of the three point gauge is to provide "automatic" gauge widening on bends (as mentioned in a previous reply), so the length of the sides of the triangle is critical. Since Mr. Pythagoras might as well have had a nice holiday instead as far as my maths goes, can anyone suggest (or be really clever and work out) the optimum dimensions for sides? I've found someone who reckons to be able to make some..... Cheers Richard |

BeamEnds wrote: Is there a definitive spec for 0-SF (tolerances etc) - I think it would be best to be able to point to somewhere and say that's where I got the info from, to avoid, er, "debates"!Hi Richard, Yes, it's listed in the G0G standards. The critical dimensions are: Track gauge: 31.2mm min. Check gauge: 30.0mm min. Crossing (frog) flangeway: 1.2mm nom. Check span: 28.8mm max. The most important gauge tool is the check gauge. It sets the position of the check rail from the crossing nose. Here's what the 00-SF check gauge tool looks like: 00sf_check_gauge1.jpg  00sf_check_gauge2.jpg Here's the drawing for it (Brian Tulley amended some of the dimensions for the final production, the critical dimensions are arrowed): 00_sf_bf_check_tool.png  The blue rectangles represent the rails as follows: v = vee nose of crossing w = wing rail (clear of the tool) c = check rail being gauged from the vee r = running rail (stock rail) (clear of the tool) f = flat section filed or machined to clear the top of the vee. To convert this for 0-SF, 0-MF, GOG-F (all use the same 30.0mm check gauge dimension): Change the 15.20/15.23 dimension X to 30.00/30.03mm Change the rail slots B to match a close fit on your rail. For both flat-bottom and bullhead the scale rail head width should be 2.3/4" = 1.60mm scale. I've just measured some Peco bullhead and it's 1.55mm. Sorry I don't have any other measurements to hand. The other dimensions are not critical. Multiply them by 1.75 for 0 gauge, or whatever is convenient. Yes, 3-point gauges are used to create gauge-widening. If you use Mr. Pythogoras you get a much longer gauge than most folks use. Generally they settle on some gauge-widening being better than none, using a shorter gauge. Here's the drawing for the 00-SF 3-point gauge: 00_sf_3point_gauge.png  The length there is 30mm, so for 0-SF I suggest 50 to 55mm. Brian Tulley can tell you where he is getting these made. regards, Martin. |

I've sent the info to the potential maker for him to give yea or nay on actually going ahead before getting definate quotes. Cheers Richard |
