Abstract
A method of making a wind turbine blade is described. The wind turbine blade comprises first and second half shells joined together and a shear web bonded between inner surfaces of the respective half shells. The blade is made in a one-stage join up process, which involves supporting the half shells in respective mould halves, and arranging one of the half shells on top of the other half shell with the shear web arranged between the two half shells. Adhesive is provided between the shear web and the inner surfaces of the respective half shells. During the join-up process, the shear web is supported by stabilisers. The use of stabilisers avoids the need for a jig to support the shear web. Stabilisers attached to an inboard end of the shear web may remain accessible after the join-up and can be removed.
