I was flying on a fairly windy day (13-15Mph and lots of sudden wind gusts), and came in a bit "hot" for landing.
Just before touch down the right wing dipped (it was the wind, I swear), and caught a piece of dirt.
I wasn't so fast that I cartwheeled, but I did do a 180* turn.
On closer inspection I noticed that the LE dowel had shifted, and when I took the wings of I saw that the LE was cracked.
To assess the damage I carefully removed some of the Ultracote. You can clearly see a small gap
between the root-rib and the wing. Before doing anything else I wicked some medium CA in the gap (top & bottom)
and taped the rib tightly to the wing. I covered the glued area with greaseproof paper, so I can take of
the tape later without any problem.
I let that cure for 30 minutes, and then removed the tape.
With a hand-held drill head (I don't have a dremmel) I cleared out the cavity slightly, to have some more room for the epoxy.
And then I drilled (by hand)a slightly deeper hole for the new dowel.
Sorry, in the heat of the moment (or about 45 minutes) I forgot to take pictures.
Instead of microballoons, I mixed equal amounts of Bicarbonate of Soda with epoxy (not to worry, the bicarb was kosher)
A by-product is that the hardening time is almost halved, so you have to work faster.
I filled the cavity with the epoxy/bicarb mixture, and pushed the dowel in. I wiggled it about
for a bit, so the there would be no air trapped inside. I wiped away the overflow, put some greaseproof paper
on the glued area, and taped the area tightly. That I let cure till the next evening (I had to go to work anyway).
Because of the greaseproof paper and tape I only had to do a little bit of sanding to smooth it out.
I then re-sealed the bits of Ultracote that came undone with my covering iron, and then covered the
corner with some scraps of Ultracote. Unfortunately I only had white or red at home, and no yellow/blue.
But it's only a small piece, and will be partly hidden under the wing-saddle anyway.
