Beschreibung
Zusammenfassung:	The present invention relates to a method of manufacturing a wind turbine blade (10), comprising the steps of placing a fibre lay-up including one or more fibre layers on the mould surface of a blade mould (60), arranging a load-bearing structure (45) and a core member (62) on the fibre lay-up such that the core member (62) is arranged between the load-bearing structure (45) and the leading edge (18) and/or between the load-bearing structure (45) and the trailing edge (20), and infusing resin into the blade mould to impregnate the fibre lay-up. The core member (62) comprises a first hole (64) with a circular cross section, a first cylindrical insert (70) rotatably arranged within the first hole (64) of the core member (62), the first cylindrical insert (70) having a central axis (71). A recess (80) is formed in the first cylindrical insert (70), wherein the recess (80) is arranged eccentrically with respect to the central axis (71) of the first cylindrical insert (70).
