Abstract: A method for assembling a shell section of a wind turbine blade includes providing a support, the support comprising a surface having a primary surface portion configured for supporting a first component and a secondary surface portion configured for supporting a second component. The method also includes arranging a second component on the secondary surface portion such that an outer surface of the second component is facing the secondary surface portion. The method further includes arranging a first component on the primary surface portion such that an outer surface of the first component is facing the primary surface portion, and such that a first primary joint surface of the first component is facing a second joint surface of the second component. Arranging the first component includes applying a force to the first component to force the outer surface of the first component towards the primary surface portion and the first primary joint surface towards the second joint surface.
