Measuring for correct axle length


For use on 21mm gauge, the drivers are measured using the back-to-back gauge, across the thickest part of the wheel hub.

Digital calipers read this as 25.2mm, so axles must be cut to this length. Fortunately the same measurement also applies to the bogie axles.

An order for these axles has gone off to Ultrascale.
