After some really good advice about my left stub wing on my 360, including a
number of good tips about how to fix it well, I ended up removing and
re-bonding the stub wing. It took a good bit of work, but I found that a
drywall spreader worked well to chisel away the Hysol and Micro. After a
good bit of sanding to remove most of the adhesives, I re-adjusted the stub
wing, drilled new alignment holes, and re-bonded the stub wing with the
outboard wing attached. The picture shows that my leading edge is almost
perfect. Obviously, I still need to smooth it out with a very small amount
of micro, but this is much better to work with than I had before.
From what I can tell, it looked like when I added the weight to the bottom
skin (plane is inverted) it moved the leading edge down a bit to compensate.
By having the wing attached, I could see this happening and compensate with
a couple mixing sticks to keep the leading edge lined up.
The only problems I have now are that the trailing edge sank a bit when
trying to line it up with the wing. It's not a whole lot, but I'll have to
keep this in mind when I do the flaps. Luckily, I haven't trimmed the
trailing edge yet, so it probably isn't as bad as it looks. I didn't
measure it, but it's less than the thickness of the skin at full aft. (And
lines up fairly well at the aft spar)
The other issue is since I bonded with the wing in place, I ended up with a
good bit of Hysol in the D section under the wing spar. Everything still
fits, but there is some Hysol at what would be the top of the wing spar.
I've sanded a bit of it away, but it's tough to reach in there.
So, overall, I'm much happier with this fit and the problems I have to fix
are very minor. Thanks to everyone for your help. While I probably could
have fixed this with micro, I think I ended up with a better and higher
quality fix.
Now, on to the right side!
