Method of manufacturing wind turbine blade with core member and wind turbine blade with structural member

A method of manufacturing a wind turbine blade (10) having a profiled contour including a pressure side and a suction side, and a leading edge and a trailing edge with a chord having a chord length extending therebetween, the wind turbine blade extending in a spanwise direction between a root end and a tip end, the method comprising the steps of:

• arranging a fibre lay-up including one or more fibre layers in the mould cavity 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),
• supplying resin to the fibre lay-up, the load bearing structure and the core member, and
• curing the resin,
• wherein 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) 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).
