The present invention relates to a method of manufacturing a wind turbine blade (10). The method comprises arranging one or more shear webs (50, 55) within a first shell half. At least one support frame (80) is fixe to one or more anchoring points (86) on the inside surface (36b) of the first shell half, the support frame comprising a free end (81) for engaging with a lateral surface of the shear web. One or more guide element (74) are fastened to at least one of the lateral surfaces of the shear web such that the guide element extends laterally from the shear web to form a receiving space (88) between the guide element (74) and the shear web (55). The shear webs are then lowered into the first shell half such that the free end (81) of the support frame (80) is received in the receiving space (88) between the guide element (74) and the shear web (55).
