I was deburring and dimpling my wing ribs today. Where the main ribs meet the rear spar at the bottom skin locations there is a tab of the rib. Is this spar and tab dimpled together? I see no way to dimple each piece separately but it sure does feel awfully thick to dimple at once. I was using a hand squeezer. Would a pneumo be better to use?
