The Home of Articulated Ugliness
Jerry,
The figure of 1.575" back to back spacing is for the space between the wheels, the air space or backside to backside spacing. {|<--1.575-->|}

G1MRA standards (since just post WWII) and now nmra standards call for 1.575" back-to-back.
The thickness of the flange can be an issue, if overly thick.
Gauge is 1.777".
I will not use proprietary gauges.
The Kadee unit was built on a pre-supposed idea of what the nmra was going to do at some point.
I would have to actually see an Aristo gauge to measure it to know.
The old Sunset Valley units I had went in the trash, as they were so far out it wasn't even funny.
I use an old Dial Caliper. Works for track, wheels, handrails, all sorts of stuff.
Buy one, you won't regret it.
BTW. 1.777" less 1.575" leaves .200".
That's less than 1/8" (which is .125") per side for flanges.
Perfect.
Aristo has a handy dandy little tool for all that stuff including levels in one ez to use implement!
check wheels, track, switches, the whole shebang!
Sounds a little wide. From what I've read, Back to Back spacing should be 1.575 inches.
