Took the carry-thru down to the airport to match ream it with the wings. Did 3 holes - one was OK, one was too large, and one was slightly oblong. Need to ream more slowly and ensure that the reamer is straight going through. After discussions with Eddie at RANS, we're ordering an oversized bolt(30) and a 7/16 " bolt (33) plus associated reamers. Our Tech Counselor will assist us with this step once we get what we need.
