This gauge shows the .688 coupler center height against a coupler with non-adjustable height on a Lionel flat car. I now have a master to adjust with.
It's a standard whether you can measure it or not. And anyone with a measuring device of any kind CAN measure it. That doesn't take away from the clever contraption you've created (though I wonder how you're going to adjust a non-adjustable coupler height car). What we SHOULD be pushing for is tighter adherence to the NMRA standards by manufacturers, instead of having to fix THEIR screw-ups! That's one of the problems with this hobby, is people's willingness to accept sub-standard products and modify them themselves, rather than demanding accuracy in the first place.
