Below taken from my report, the beaming deflection was 0.31mm.
Not too shabby for 25x25x1.6 mild steel tubing

Objective
To test the ICV Clubman chassis constructed by Dave King in accordance with the prescribed beaming test to determine its structural adequacy.
Methodology
The Methodology set out in the National Code of Practice for Light Vehicle Modification and Construction
has been utilised.
The vehicle’s suspension was made inextensible by replacing the springs and dampers with rigid rods.
The vehicle was then supported on axle stands under the axles.
A set of 10 dial indicators were installed on RHS members clamped to the chassis five each side
between the axles.
The following table shows the longitudinal and transverse positions of the gauges.
Position
Longitudinal
Position Separation
F -70 700
1 785 1150
2 1340 1270
3 2145 1270
R 2380 1500
Table 1 Gauge Positions
All gauges were read and the measurements recorded.
The vehicle was then loaded with a total of 272 Kg applied at the seating positions.
Each gauge was read and the results recorded.
The load was removed and the results again recorded to determine if any plastic deformation had resulted from the loading.
