Well I fell like I have crossed a finish line. The top wing skins are riveted and the wings are now ready to come off the stand. The wing stand that I had build was a compact design...but it worked like a charm. True that access to the end ribs was limited. To dimple, or countersink the last 3" required the wing to be removed from the stand. but given that I could still park the cars in the garage it was a small price to pay, and only resulted in a few more build hours as I had to re-check level and wing twist any time I had to remove the wings off the stand. Which i've I had to guess total additional hours, I would peg it at about 10 total. But the best part of it all....the wing stand could be partially disassembled and rebuilt into the wing cart!
