fibreglassing is a challenge over the open sections of wing!
the solid balsa areas seem straightforward enough so far but the bits between the ribs are a bit of a mess so far!

the light cloth I am using combined with the low temperatures in the shed meant for a pretty gloopy glue.
will need to get some alcohol. Denatured alcohol is called surgical spirit in the uk so I'll be off to the chemist to get some of that tomorrow...

Cheers
Steve

Hi Steve

Would you be able to use some traditional covering over the open sections of the wing before you apply the glass fiber?

This would give you the support you need and not add much weight at all.

Just a thought

Ben

I probably could have but I have done it now.... if it looks really horrible I'll have to build a new wing.

That is a good idea for future application though...

I am sure it will be ok..

Oh no...

You cannot apply fiberglass over the open sections of the wing! If you have already done so, just trim it out of the open sections after it cures then proceed to cover the wing with iron-on film.

I thought you were planning to fully sheet the wing, which is why I suggested fiberglassing it. I guess I misunderstood!

Haha that explains why I can't find any info on how to do it!

Will do that, I am surprised how easy it is to do over a solid wood structure I'd say it is easier than applying iron on film. I'll figure out something

LOL

Sorry Steve but thats funny!

I wonder what the "scalloped" surface of the wing would have done to the aerodynamics???

Don't worry Chris, when they make something idiot proof they simply find a better idiot.

It just didn't occur to me that I couldn't cover an open section of frame.

I'll simply cut out the scallops and cover it with film.

The wing should be quite a lot stronger than it was as a result of the glass. Which was the whole point of doing it.

I am now a convert to fg finishes it is cheaper and easier than film covering once you have a supply of resin... And it takes time to do which means I get to spend more time fiddling with it...
