1. A mould for making a wind turbine blade shear web, the shear web comprising a longitudinally-extending web panel and a mounting flange extending along a longitudinal edge of the web panel and transverse to the web panel, the mounting flange comprising a first portion extending on a first side of the web panel and a second portion extending on a second side of the web panel,
the mould comprising:
a longitudinally-extending main surface shaped to form the web panel, the main surface having a longitudinal edge;
a side surface arranged transverse to the main surface and extending downwards from the longitudinal edge of the main surface;
a base surface arranged transverse to the main surface and spaced from the side surface, the base surface having a first portion extending below the main surface to a first end of the base surface and a second portion extending above the main surface to a second end of the base surface, wherein the first portion of the base surface is spaced from the side surface to define a mould cavity between the side surface and the first portion of the base surface, the mould cavity being configured to form the first portion of the mounting flange; and
a datum-forming surface extending transversely from the second end of the base surface and defining a longitudinal edge at an intersection of the second portion of the base surface and the datum-forming surface, the second portion of the base surface and the datum-forming surface being configured to form the second portion of the mounting flange, and the datum-forming surface being configured to define a longitudinal edge of the second portion of the mounting flange.
