Aspects of the present invention relate to a repair insert (1-n) for repairing a box member (3). The box member (3) has a plurality of walls (11-1, 11-2, 13, 15) which form one or more cell (11-n). The repair insert (1-n) includes a first clamping member (21-1) for clamping against an interior of one of the walls (11-1, 11-2, 13, 15) of the box member (3); and a first engaging member (23-1) for engaging a first one of the walls (11-1, 11-2, 13, 15) of the box member (3). A first tensioning arm (27-1) is connected to the first clamping member (21-1). At least one first reactor arm (29-n, 31-n) is coupled to the first tensioning arm (27-1). The at least one first reactor arm (29-n, 31-n) is operative to apply a biasing force for biasing the first engaging member (23-1) towards the first wall (11-1, 11-2) when the first clamping member (21-1) is clamped to the box member (3). Aspects of the present invention also relate a vehicle (5) including a repair insert (1-n); and a method of repairing a box member (3).

An apparatus for the orbital cutting and calibration of tubes is provided. The apparatus has a rotor having a central hole through which a tube to be cut is movable along its longitudinal axis, the rotor being drivable to rotate about a first axis of rotation coinciding in use with the longitudinal axis of the tube that is supplied to the apparatus. The apparatus has a cutting device having a first support body mounted radially movable on the rotor and a cutting tool carried by the first support body, and a calibration device having a second support body mounted to be radially movable on the rotor and a calibration tool carried by the second support body.
