I have just received an order of track components from The EM Gauge Society and hoping to start building points and track for my layout. Amongst the items I ordered was an EM gauge block by D.D.Wheelwrights which I tested on a short length of Ratio EM gauge track and to my surprise it did not want to sit between the rails. I thought maybe the track was slightly out of gauge so I measured the block gauge with my digital vernier gauge and found it to be 18.26 mm. I know it is only 0.06 mm out but is this regarded as acceptable or should it be exactly 18.2mm for it to be of any use. The DCC Concepts EM gauge track gauges that I also ordered fit on the Ratio track perfectly and are 18.2mm as measured with my vernier gauge. Have any modellers out there encountered the same problem with these gauges?
