After thinking about the next step in the routing of the smoke oil line, I decided I needed to make the piece just aft of the carrythrough spar a separate piece. This'll allow me to flare the forward end by removing the bulkhead elbow and sliding it through the spar. This first iteration was a little too short. It doesn't show in this image, but I need the spanwise leg to be aft of the stiffening ridge in the side rib so that the spanwise run will not interfere with the crotch strap attach brackets.

It took me a couple more scrap pieces (due to measuring errors) to make this bracket. I think it's going to be a keeper.
