Completed enlargement of tooling hole. Fitted rubber grommet in hole. Finished attaching three Adel clamps to spar. Ran coax cable. (Used UniBit to complete hole enlargement. Nice!) Fitted skin to skeleton. Clearance between antenna puck and skin on left side was insufficient, so filed skin a bit, and also fabricated and installed two thin shims below left side of puck. Attached antenna elements and checked puck alignment with VS structure.
