Brief Description:  Open rivets holes to #12 for the 6-14 rivets

Project is to drill to size (#12) the long AN470-AD-6-14 rivet holes on the inboard ends of the Right Wing Spar. Spacers of 1/4" were placed under the visqueen, that was taped to the part, to keep the spar caps level with the table. Clamp part lightly once it is lined up, (the laser light helps here) to prevent the part from lifting or separating (good for some things, but not sheet metal) while drilling.
Process:

Drill #30 in 6 places along the line of 6W3-6 for the 8-32 screws and wing nuts. Make sure the smooth side of the washers goes toward the part surface.

Install the 8-32 screws, washers, and wing nuts.

Remove silver clecoes and drill all #30.

Install Copper Clecoes every 4th hole.

Drill all to #20

Drill each side of the 8-32 screws open to #12

Install 10-24 screws, washers, and wing nuts on each side of the 8-32 screws.

The screws are long enough to hold the parts together where the clecoes really aren't.

Remove the 8-32 screws and finish drilling all holes open to #12
