Landing Spindles

[MortarThePoint]

Along the landing, we're having Sapele hand rail and base rail with painted spindles in between and painted newel posts. The stair itself is an Open Stringer (or Cut Stringer) design and we're having Sapele treads with painted risers, stringer, spindles and newels. On the stair, the spindles have to be dowel fixed into the treads since there is no stringer top edge to put a base rail on.

 

Every installation I see for spindles along a landing involves the glued packers, a blob of glue top and bottom on the spindles and perhaps some narrow pins through the edge of the base rail and hand rail into the spindles. Does anyone dowel their spindles into the base trail? Would that be excessive? I want to make sure I don't have an unpleasant surprise with the BCO if he says I should have added some fixing to the spindles.
