Completed the aft spacers to the RH spar. Drilled the aft ribs to the RH spar. Installed the aft spar and drilled it to the ribs. Rearranged the sheet stock in storage to get out the RH aft upper and lower wing skins. Leveled the RH wing skeleton and placed the upper aft skin on it. Not quite satisfied that all is square yet, so I'll leave it spring-clamped in place for now and go back and re measure it all later.
Spacer blocks w/ spring clamps to hold the spacers in place. I use these spacer blocks a lot.
