Clecoed the two inboard HS-905 nose ribs to the front spar assembly and match-drilled with 1/8” drill.  Clecoed the two inboard HS-1004 inspar ribs and match-drilled using the same 1/8” drill.

Constructed the cradles to support the HS-1001 skins.  Inserted the skins ensuring the angled end of the skin faces inboard.  Clecoed one nose-rib to the skin to test the fit – wanted to ensure I ground enough off of the tip of the rib to prevent denting the leading edge – looks good.
