The last three weeks were rather demanding, and I haven't spent a single weekend in the UK. A lot (!) has happened privately, but nothing on the plane; that's why you haven't see any updates here.
Well, anyhow. About three weeks ago I dimpled the center holes of the HS-702 spar channels and started countersinking the corresponding holes in the HS-810-1 angle. Of course I was too stupid to follow the instructions in chapter 5, so I countersank the first hole way too deep. Stopped after that hole, thinking that this can't possibly be right, and last week I ordered a new HS-810-1. It arrived three days later (woohoooo!) and tonight I tapered it, match-drilled it, and bent the ends to 6 degrees. Doing it for the second time went much faster that the first time ... The last step for today was to countersink all four center holes of the HS-810-1 and HS-814-1.
