I've just got my calipers to them and the results are:Kato: Axle dia 0.97mm, muff length 7.51mm, muff length required to achieve NMRA back-to-back spacing 7.72mm. It may be best to reduce the diameter of the inside of the muff by say 0.02mm and one could ream or drill to get a perfect fit - that's got to be better than finding 0.97mm is sloppy.Bachmann: Axle dia 1.17mm, muff length 7.46mm, muff length required to achieve NMRA back-to-back spacing 7.85mm. The axle has a knurled part which means it's going to end up being a push-fit.I'm pretty sure these measurements will end up being ok, but if anyone cares to check them I won't be offended
