Fluting the ribs

Over 3 months since I last posted.   Not a very good blog is it?  I pretty much took the summer off from working on the plane so I don't have that much to report. It was just too hot to hang out in the airplane factory for very long.  Project momentum, which never really got going after the wing kit arrived in April, just kind of went phftt.  A very wet phftt.  Lest Mr. B. think I'd given up (and demand all his tools back) I thought I'd post a brief update and come back later when I have pictures of actual completed airplane parts to show.  Now that the lame-o excuses are out of the way, Page 15, Step 1 tells us to "flute" the ribs.

 Honestly, I don't know how other RV builders do it without having one of these around!
