Hi, I was talking about the check rail chairs
If we take a step back looking at the reasons for Exactoscale producing their own track system. After Exactoscale demerging from the P4 & S4 group and the death of Bernard, Len Newman designed a track work system funded by Andrew Dukes and took over the Exactoscale brand name
Most of the Exactoscale range (especially the special chairs) were designed for P4 track building for use in the P4 Track Company turnout and crossing kits.
Some products were designed exclusively for 00 and or EM gauges, others were able to be used in all 3 gauges
The check rail chairs were only ever made to P4 gauge standards. 0.64 being standard P4 chairs and 0.8mm being gauge widened
The standard EM gauge check rail gap being 1mm. With 00 gauge it depends on which of the many varying standards the builder, the smallest being 1mm (00SF of DOGA fine) and 1.25 perhaps for the track builder most common
Without modifying the Exactoscale checkrail chairs, the gauge will be narrowed, this could cause running issues on smaller radii 00 gauge turnouts and crossings on the curved exits
I have been reliably taught over the years to set the check rail from the Vee using a check rail gauge, not setting the check rail from the stock rail (if using one of those dual use roller gauges or other types)
I have read an interesting article in a Scale 7 mag where the builder only uses a "mint" gauge (no roller or 3 point gauges used). I assume the mint gauge both automatically has the ability to set the check rail (from the Vee) and gauge widen the stock rail, if required where appropriate. But this is my assumption
I do accept 00 gauge is the odd one out where gauge widening is in built to the tolerances of the wheel specification, and a certain amount of fudging can be tolerated. But be warned fudging does not always work. No doubt there will be those who get away using them as are!!
This is not a criticism, but others should be aware of the potential issues of using this item
