I recently received an email from someone concerned about my apparently absent progress. It's great to know people are following = thanks for the support.
In the last few months I discovered I wasn't happy with the excessive bend radius on my spars. Too generous so that the ribs didn't fit well at all. So I ordered more aluminium and had my spars rebent on a CNC brake.
I am now at the point where I am painting my spar parts. Very close now to re-assembly and riveting.
