This is what I did, so this is correct. Standard military FUBAR.
If that sounds a bit rigid, it's because the other side is pretty close to this side  so we takes it.
Plans show for the front to be filled with body putty, and Glen has suggested epoxy and micro balloons. I like the mb idea, but first will fill some of the area with triangle stock...just because balsa is lighter than epoxy...

OK! Three piece wing needs a wing tube! Well there is another way, but I'm not sure about the engineering involved. 
I acquired a 1" diam (that's 2.54cm to you modern guys) CF tube, courtesy of the generosity of Mrs. Miller, whose pink shower curtains now lay on the bathroom floor beside the tub. Thank you GWS! 
A one inch tube requires a socket, into through witch  one slides the tube whence assembling the pieces of subject wing. Mrs. Miller's Mr. Miller and I measured the wing, from rib 7 through to rib 7, at 44 inches. A cursory trip through the web/net/google/yahoo leads me to belive no-one sells sockets at 44 inches. And if they did the cost of getting it here would be yuge, bigly, and ginormous.
Mr. Cool talked me through the process: secure CF tube; wrap said CF tube with 2 layers of wax paper; wrap fiber glass cloth around the tube with lots of epoxy/resin. Once cured, remove CF tube from wax paper; remove wax paper from inside the fiber glass socket. EASY 
Removing tube wasn't bad. Removing wax paper from INSIDE the new socket, another story....

Don't you just love it when something comes out right??? I think I would, if that ever happened  .

Actually, the wing tube socket did just that!! Tube slid out of the socket/wax paper thingy with little effort. Then used long needle nose pliers to get in the tube a bit and untwist the WP wrap stuck to the resin inside.....Unfortunately this technique only goes so far, and that's not as far as the other end of the tube. So, to make it easier, almost easy, I knew the lengths I needed for the tube - center and 2 outside wing panels. Cut the socket into three, and unwound the WP wrap in three different tubes. 
And, dare I say AND (!!!) the tube slides through the sockets as slick as **** through a goose. No play, but no push either....This might work.  Now I'll slide the sockets back on the tube and clean up the rough stuff, but inside fits. 
Thank you Al kind sir.

Don't see any discussion. Monologue maybe, discussion no.

Besides, Mrs. Miller doesn't read these pages does she? Ipso, not going to see where the shower curtain rod went...

Thanks Greg. All good info. This is really what this build is about - new ideas. I'm sure some guys newer to the hobby read my prolonged nattering and think "jeez do they really do that kind of thing?"
Course, others read it and think "wish the bugger would shut up and finish the darn plane.."

I found running the cutter backwards works best. Forwards it just digs in ....
Nice work sandy... maybe flitetest will have a hurri soon. Then off to dollarama... y

Never heard about turning an adjustable circle cutter backwards. I use the same cutter to cut plywood for round bulkheads using a large drill press turning at a moderate rpm rate and have not had an issues with the cutter digging in so long as the material being cut is securely held down. If the material being cut is not big enough to clamp to the drill press table I have used a piece of laminate floor as a backer/holder and stuck the material to be cut to this, using 2 sided carpet tape. It will usually hold onto plywood long enough to cut the circle but it sticks to the laminate floor piece or any smooth surface material like sh*t to a wool blanket

Dilemma time: If you look at the picture of the socket tube in the center section, you can see above the tube another set of holes through the ribs. Now those holes are closer to the center of lift of the foil. It would be nice to have the wing tube located in those holes, further forward. But, as you can see, the wheels block off anything going through those holes.
If I use those holes, My wing tube only grabs 2 ribs, about 7 inches, in the center section. Using the holes I show, I can run the tube all the way through.
So question: Can I get away with the front holes (7") either side, or am I better using the back holes and being behind the center of force..................

haha Hysol is the only thing I recognize from the past 10 posts...  well that and curtain rod.    Keep up the great work Sandy, I am still enjoying the thread after 5 years and counting!
