I think all is working again now. Please leave a comment on a photo somewhere if something you need is not working still.

To carry on the conversation that DD started: The engine structure here was wrapped with 1/16" SOFT balsa. I edge-glued sheets together with Cyno then sprayed it down with WIndex, wrapped it around a piece of PVC pipe about the right diameter and let it dry overnight, The sheeting was CYno'd to the structure and trimmed. The front fairing was tacked to the fuselage, sprayed with Windex, then held in place with painters tape until dry (X 2 to get the other side). IT may be just my imagination, but the Windex seems to have just enough Ammonia in it to really relax the wood grain.

Detretuis from converting about 10 ft of 1/8" X 5/16" basswood to airfoil shaped strut material. Now I just have to figure out how to make the joints in the "N" struts.

Another view of the saddles. Out of scrap balsa I built 4 different sanding blocks fair teh airfoil. If some ham-handed idiot wouldn't have crushed several ribs during the process, requiring replacments, I would hav been done much sooner. Now on to the strut & rigging attachment points.

Spent most of the day sanding and strueing up the wings. Never done this before. My enigineering & woodworking background has proven the worth of "jigs" over the years. Here is one of teh wings supported by three saddles that allowed me to get the bottom of the leading & trailing edges truly flat and also make sure that the undercamber of the airfoil was consistent.

Top wing done. The plans that I am working off of did not have ailerons, so had to extrapolate/interpolate/WAG them; think that I'm pretty close. The wing center section/dihederal brace took most of the day (when I wasn't shoveling snow).

Nearly 200 individual parts here, Took a day and a half to git R done. The little pile in front are the puchings from the alignment tool. I think the next model will be Laser-cut.

There are about 15 rib blanks clamped in the patterns. The red edge, applied with a sharpy, is a warning stripe to let me know if I have gone to far. I roughed the shape out with my drum sander then used a fairing board to refine the ribs. The notches were roughed out with a razor saw then refined with a small bastard file.

About 1/3 of teh rib blanks in waiting.

With about 80 full size ribs to cut out of 1/16" sheet, Imade a jig out of 1/8" lite-ply to insure consistent results. There are two 6-32 stove-bolts to clamp the rib blanks between the patterns. The thingy to the left is a piece of 1/8" O.D. brass tube with the inside sharpened with a countersink which should make some nice holes in the rib blanks using the pattern jig in front.

Assenblage of parts waiting to be doped and tissue applied. IT was (-)22 deg. F. overnight and is going to get up to (-) 8 deg. today: the dopeing can wait. Besides I have to get ready to watch the Steelers wump the Broncos.
