Wind turbine blade mold with built-in high precision geometric references on B-surface

A method of forming a wind turbine blade comprising:

• providing a first mold surface, with at least one aperture located therein;
• providing at least one stud having a first end and a second end defining a length therebetween, the second end of the at least one stud disposed within the at least one aperture;
• providing at least one pin having a first end and a second end defining a pin length therebetween, with the second end of the at least one pin releasably connected to the first end of the at least one stud;
• releasably coupling a first pin extension to the first end of the at least one pin;
• depositing a plurality of layup segments of fiber material above the at least one stud, with the first pin extension passing through each layup segment;
• inserting a structural component of a wind turbine blade at a location determined relative to the location of the at least one pin;
• attaching at least one disc to the at least one pin, wherein a portion of the at least one disc is configured to engage the structural component of a wind turbine blade.
