Gauge 0 wheel castings, by INTERNAL DIAMETERS

HOME

TREAD DIAMETERS are a fairly good guide to wheel size, but remember that due to apparent tyre thickness varying from wheel to wheel by 3 to 5 inches, you will need to refer to the diagrams to find the internal diameters and to see the machining allowances on the castings.

Gauge 0 scales: B = 1:43.54 (7 mm/ft),   C = 1:45,   Q = Narrow gauge at 1:45.

Finding the right casting size if you know the apparent tread.

Look for the casting i/d which matches your model diameter on the tread (the normal nominal o/d), less TWICE the apparent tread at your scale.

Example: 5'0" nominal dia. wheel with a 3½ inch apparent tread at a scale of 1:32.
Model dia on tread = 47.6 mm, twice the apparent tread = 5.6mm, so your target casting internal dia is 42.0 mm.

There is some variation in the castings, but the measurements are usually accurate within ± 0.1 mm.
