Anton Stedman Posted July 4, 2020 Share Posted July 4, 2020 Hello,Aplogies if this has already been mentioned, but I couldn't find it anywhere on this forum. I have a second hand R3592TTS Hornby Class 31 purchased from Hattons which I have been waiting for, for ages, so when one finally came onto the Hattons website in a 'like new' state, I took the chance. The problem is that on most of points it is causing a short even at up to half throttle. None of my other locos do this and I think it is to do with the width of the wheel base, if that makes sense? Could this be the problem, has anyone else had this? Thanks in advance Anton Link to comment Share on other sites More sharing options...

Anton Stedman Posted July 4, 2020 Author Share Posted July 4, 2020 Hi,Thank you for the quick reply. Here are 2 of my readings from my digital caliper. Seems a little low to me. They are all in the range of 14.3mm. Am I doing it right?!/media/tinymce_upload/8fdd67648d7f00b688118263032f7d18.JPG/media/tinymce_upload/8802e5331e837003b203c5e28552b897.JPG Link to comment Share on other sites More sharing options...
96RAF Posted July 4, 2020 Share Posted July 4, 2020 Also check that you have not lost a traction tyre as if so this will cause that wheel to track badly across points. Link to comment Share on other sites More sharing options...
Chrissaf Posted July 7, 2020 Share Posted July 7, 2020 If the vernier is accurate, then 0.2mm might not seem a lot, but it can be enough to cause issues. The most accurate way of measuring B2B is to use a purpose made brass gauge like the one in the image below. The gauge can also be a good tool for making it easier to adjust the wheels. Basically you make the wheel B2B wider than 14.5mm, insert the brass 14.5 gauge then close the wheels up against the gauge. It takes some of the trial n error guesswork out of the adjustment process. Most wheels are tight friction fits on the axles, thus some adjustment is possible../media/tinymce_upload/7d6af6539fd2651b9708c143e29c5a95.png.

Anton Stedman Posted July 7, 2020 Author Share Posted July 7, 2020 The vernier is relatively new so I think it should be accurate but will probably buy a brass gauge since I have lot of other coaches, wagons, etc. Does that mean the vernier wouldn't really be useful if I brought the gauge or are they used together?

Chrissaf Posted July 7, 2020 Share Posted July 7, 2020 In principle one would use one or the other, with in my personal view a preference for the brass gauge. With the vernier being used only if nothing else better was available to use. I find the brass gauge more efficient to use and more accurate. The only downside to the gauge is that subject to specific rolling stock designs, access for the gauge can sometimes be problematic, sometimes needing parts of the chassis removed for gauge access.
