Posted by Riveted the right main ribs onto the right wing spar. This went quite well, and only 2-3 had to be drilled out and re-set (mostly due to bucking bar slippage). Haven’t been great at keeping the builder’s log up to date in the last month… at some point, many many hours were spent deburring these ribs and priming. Painstaking work and no pictures of that progress. So including a few extra pictures of this stage!
