What about pieces of wire into the embossing, before glueing the surface to the wing core?

Cheers,
Frank

That sounds like a good idea, Frank.  I'll have to keep that in mind for the next time.  I didn't expect this problem this time around since it worked so well on my Hanriot.

Sorry to hear of your rib issues Ken. I am however positive you will prevail!

When I did the wings on my FE-8 I used a base core coated in testors liqued glue and double side tape , forming the skin over the core and glued the edges . No damage to the ribs . This is 10 years ago now and wings are still perfect .

I do like the wire idea , would a stiffer wire work well ? Would a slight curve to the wire holding its shape and then super glued in place ?  :-\

Looking forward on seeing on it turns out .

Salvage attempt # 284 (seems like it)

I glued 0.020" X 0.020" styrene strips on the top surface of the wings after sanding off all the previous rib detail. 



Then sanded the ends near the leading and trailing edges until flush.  Wing on the left is rough sanded, the one on the right is finished.

After cutting out the ailerons, I brushed on a coating of epoxy fiberglassing resin to blend in the ribs into the top surface.  The coating is self leveling, glass smooth, and hard enough to sand into a final shape.





We'll see how this works out.

After a light sanding, it will be primered before painting.

Looks promising, Ken

I have some of those Altoids tins somewhere

Looking forward to seeing how this works Ken, I suspect the answer is "very well". This is such an inspiring build, really enjoying seeing this unfold.

I really like the outcome! Looks like linen over ribs :)

Hello all,
I am liking how this looks at this stage.  I let it cure overnight and today I will do some light sanding and primering to get a good look at it.  Hopefully, I won't be too distracted by the Roden Fokker Dr.1 and Albatros D.iii that should be arriving today!

I use some Altoid tins for holding small parts.  My wife bought a case of Altoids, so I have these tins everywhere.

Thanks for looking and commenting.

The wings/ribs do indeed look promising! I am sure you will get them in final form in no time!

That's what I'm hoping, Rick.  I want to get this project moving toward completion.

That is an unfamiliar technique, but it looks very effective. I am thinking that with slightly taller ribs sticking up you could solve the issue of external rib battens as found on a MoS type N or an I'lya Muromets. Adding them later brings up the problem of getting them on straight, whereas your method would ensure they are all perfectly straight.
Really looking forward to seeing them morph into Tommy wings to match the rest of this great build.

That is a novel idea with the fibreglass resin - I would not have thought of that. Looking at the results so far it looks as though it could be the answer to your problem.

After a bit of sanding and cleaning up, I cut out the aileron torque tube opening and added the spar.  Then primered.







I think the wings look good enough to proceed.  Next time I use this technique, I will not sand the ribs quite so much near the leading and trailing edges.  In the top 2 pictures, the wing looks warped but its only the camera lens distortion.

Thanks for looking in on this project.
