There is an interesting reply about the EMGS flexitrack gauge narrowing on RMweb http://www.rmweb.co.uk/community/index.php?/topic/139084-emgs-commissions-peco-for-rtr-em-gauge-bullhead-trackturnouts/page/19/ second from last post at the bottom of the page Anyone else noticed this ? |

I was just about to order some from the EMGS as it seemed to be an easy way of getting track for use away from the main bit of the layout. It is even worse for me as I run EM-SF at 18mm gauge and the whole point of using EM flexitrack is to get a wider gauge for the bendy bits, not a narrower one BTW who at the EMGS is responsible for product development and similar matters ? I would have thought the Trade Officer just maintained the stock and dealt with orders. Rob |

I would imagine that the technical side in designing and making the tool is in Peco's hands. As I said either here or on RMweb, Exactoscale has two track bases in their fast track range, but that is not because their track narrows, just that it is needed on curves under a certain radii. I have no idea though what these radii are in either EM or P4 gauges |

Hi Rob Measuring things like gauge can be fraught with issues. I notice Penlan was using what looked like one of the cheaper electronic verniers, in fact it may be the same as the one I use. I wouldn't trust it for accurate measurements. Also there's the question of why would it gauge narrow on curves, but presumably not on straights. Think this needs looking at in depth before reaching any conclusions. Cheers Nigel |

Hello Nigel, Yes, I agree with your comments. I ditched my electronic calipers a year or two back and switched to dial one's which are better in as far as they agree 99.9999% of the time with my micrometer ( after doing a metric-imperial conversion ) and the digital ones had a strange knack of having a flat battery each time I picked them up ( cheap batteries ? ) I was going to suggest ( tongue in cheek ) that Penlan on RM had used the 3 point gauge the wrong way round - done that myself more than once on hand laid curves.

The reason the batteries die so quickly on cheaper calipers is that the on/off button only shuts down the display - the rest of the electronics is still active apparently (there's info on this on the web). Some have wired in additional on/off switches to isolate the battery completely; the other option is to remove the battery if you're unlikely to use it for a while. HTH Brian |

Hello, I bought one from Maplins. About as accurate as a guess depending on how you close one eye. Regards. |
