MikeH_83 Posted February 20, 2018 Share Posted February 20, 2018 Hi all, I am currently making my track to 4-SF (00-SF) and I am wondering at what radius curves I should change from using the normal 2 rail track gauges to the 3 point ones? Also if I remember correctly with the 3 point gauges you haveto use the 2 side part on the inside of a curve? Cheers Link to post Share on other sites More sharing options...
RMweb Premium Siberian Snooper Posted February 20, 2018 RMweb Premium Share Posted February 20, 2018 The two prongs go on the outside of the curve, otherwise you end up with gauge narrowing. I tend to use them on all curves, on the shallower ones it won't make much difference and for long sections of plain track I revert to 16.5 ready to lay track.

RMweb Premium Izzy Posted February 20, 2018 RMweb Premium Share Posted February 20, 2018 You can really use 3-point gauges with any track, from dead straight to, well, as tight as you need/want. The key is that the amount of gauge widening is roughly proportional to the tightness of the curvature. This presumes the gauge uses the standard size design with the distance between the two legs being twice the track gauge. As has just been posted, the two legs go on the outside rail, otherwise the opposite effect of gauge narrowing occurs. regards Izzy Link to post Share on other sites More sharing options...
MikeH_83 Posted February 20, 2018 Author Share Posted February 20, 2018 Thanks both! Didn't want to make lots of track and then find out I made alot of mistakes lol Link to post Share on other sites More sharing options...

Cheers IN general with 00-SF plain track , you don need any gauge widening down to 3' radius curves , below that and you will need to increase the gauge Link to post Share on other sites More sharing options...

Most curves are above that at almost 6' Cheers Link to post Share on other sites More sharing options...
