Brief Description: Preparing for Fwd Spar mounting
In preparation for locating the forward spar, I used the laser level to add lines locating the centerline of the spar. (So much better than the old days with spirit and water levels!) Lines were also drawn on the side of the fuselage that will be the centerline of the inbd rib. Removed the aft bulkhead and started to prepare it for riveting. It is too hard to get the spar located and drilled with all of the aft bulkhead clecos in the way.
By the way, I followed the plans with respect to which rivets are flush and not, but it would be better to look ahead in the plans to be sure. As it turns out, some of the upper outer rivets will need to be flush as well. This is to clear the vertical tail attach brackets. As a side note, when you offset the vertical fin, it does not leave much room for the brackets. I may do something different from the plans when I get to that stage.
