Celebrated my daughters 33 Birthday today - geesh, I'm getting old ! Countersunk #40 holes for rivets, and #33 holes for blind rivets. Added some fiberglass cloth & epoxy resin into aft end of Tip - I was concerned when I cut about 1/4" off of the end to be flush with Aileron, there will be little material to nothing holding top and bottom together at end of Tip.
