Brief Description: Layout rivet lines on bottom skin
Just talked to Zenith and I will be making the access hole 540mm rather than 560mm. Now all the numbers line up front to back.
Also going to use 9mm edge spacing for the longeron rivet lines.
Layed out and pilot drilled 6-b-1-4 rivet holes. Raised the piece above table and used edge marked set to 9mm for the lonegeron.
Drilled hole in each intersection and used rivet spacing tool to keep things consistent. When it got to the wide sections I measured 20mm each side of center line and drilled holes there so the rivet spacing tool could reach.
Flipped the piece over and attached two 6-B-1-7 Cross Stiffeners.
