That is, in fact, a tube flaring tool for AN flared fittings. Piece of cake to use. I'm fortunate in that our EAA chapter has a tool crib from which I could rent it for $5. They are about $100 now I think, I don't intend to make that many flares.

A lot of work this week, but not much to say. The left wing is now covered. Some extra poly-brush on the fiberglass and taking care of pinholes before spraying poly brush worked to prevent pinholes during spraying.
I got a start on the wingtip, but this one will be a bit more challenging. The scribe line(s) are in bad shape. They are missing entirely in some places, and the parts of scribe line I can find aren't colinear. I'm going to use the right wingtip and a laser line to make the left a mirror image of the right.

Ignore the scribe line. Just try to make it square and take off as little as possible.

That's what I've read in other threads. On my right tip, the scribe lines ended up being perfect. I'm glad I did that one first. I'll be using a laser to make my own square cut lines. I think it will be fine.

Really great quality work there Brian. Wings sure look more like airplane wings with the Poly Spray on. Great progress.

On the Horizontal stab rib third from the tip, it appears in the manual that it should butt against the metal rib. The instructions note that the tolerance is 1/8" and that ribs can be trimmed to move them against the ribs. It specifically mentions the 308 rib. This one is the 304 rib. Without trimming, it sits a good inch away from the metal rib. If I trim it to put it against the rib, the contour will be off. I also note that the distance from the stab centerline given in the manual is 34 1/2 inches. The inboard side of the metal rib is at 35 3/8. Am I missing something here?

I had the same concern; I ended up putting it against the metal for good stiffness and then readjusted the other ribs for fairly even spacing. When you do this, also take into account the positions of the elevator ribs, because you will want them all to line up for good appearance. In my opinion the very tiny effect on the airfoil profile is a non-issue.
