"I continued with the marking and measuring the rear spars. I finished the right spar marking anddrilled the rivet holes the control rod push holes and counter balance holes. I cut the wing tip angle and the root angle on the spar.
I did the same for the left spar and now they are both ready for locating all the angle and attachments on the spar pieces and upsizing the holes, drillng the bolt holes and then prep and prime.
After I come back from San Francisco. Good progress and nice tobe off the main spars. Sneaking a peeek at the next steps in the plans of joining ribs and bell cranks to make it a real wing."
