Primed a small batch of parts including the spar extensions, gusset plates and tie downs for both left and right spars. Will proceed with right spar then come back to the left.

Final drilled and riveted the spar extension. First rivets bucked in a while and had to drill out a few just because they weren't perfect.

Clamped and drilled the lower W-1028A and B taking care to not drill the holes indicated in the plans. I may have drilled a hole I wasn't supposed to because the edge distance on the last hole is too tight on the 1028B. I may need to splice a short J channel piece.

Countersunk the rivets for tank attach and access panel nut plates. Held short of countersinking all the others - need to give my arms and my drill a break. A good task for weekdays after work.

[Update] that mis-drill is going to be a problem. I even masked off the holes I wasn't supposed to drill, but I thought it was only the nut plate holes for the access panels. It appears it extends a little beyond the access plates as they had to modify the spacing. Going to try to salvage form the extra lengths of j channel I have and come up with a minimum length to order from Van's. Trying to avoid another 8' long piece. I don't need it until closing up the bottom so may just have them throw it in the fuselage kit.
