Eventually I have had to turn it over so you can all have a look at the mess. After a lot of sanding I have chopped out the sheeting for the struts.

Has I am in winterton North Lincolnshire it will have to be posted. First I have to find them I've looks where I thought they would be to know avail. I will look in the morning to see if I can locate them I say them because I should have two and one for a phoenix 2400. Yes I've had a smashing time recently. 🤣

Did you actually fit a dihedral brace before you glued the wing halves together ?
Hi Keith, yes I used the ply braces that was supplied. They are not obvious but they are there in this photo.

If the balsa is dented why not try the old trick of a drip of water on the dent?
Thanks that's works a treat.
After what seems like hours of sanding and scraping and more sanding this is what it looks like.
That's going to have to do, is my thoughts at the moment as there is lots of wing left to sand.

The centre top shooting and now being completed and sanding has started, on a wing of this size sanding could take some time.
We will see. There are some imperfections that were benefits from being filled, I am thinking of making up some filler, for the first time in ages

Not much dihedral -is it the aileron version?
No it's the three channels version and it has two and a quarter inch dihedral on each Wing, this may be a better picture

Yes kc, I hate undoing what I already have done and it was so tempting just to glue it together as it is that that's what I did also it fits in the room and will stand on its wing tip for storage. I also realised for me it is more important to minimise the work at the field and the consequences of a single Wing will simply be put up with.

I shouldn't have posted those last two photographs, they were too good to be true, because when I checked the wing alignment they were out and I had to fit a wedge to make good.
And the bottom was even worse so I have not taken any photographs of the mess. While I am in a confessing mood I also made a mess of the first Wing which needs a bit of sorting out beyond that it all looks good and probably would fly anyway as it is.

Thanks for the compliment John,
Today I decided to test fit the wings together.
Then just like a bolt of lightning out of the blue the bright idea hit me, why not just glued the wings together I thought?

With the wing turned over the top of the tip has been completed.
The first cap strip has now being glued in place with the rest ready and waiting.

The bottom of the tip have now been finished and the cap strips done.
Just to repeat on the top, incidentally the sheeting of the tips is not an easy option. I am now wondering if it was all worth it but that's me liking a challenge.

Thanks John for the excellent explanation, as usual, you have made it sound easy for the tubes. As it happened I have the phenolic tubes scaled from the plan I just thought that using the ply braces would be easier. I am now beginning to think that the phenolic tubes will be easier due to your explanation. As to the sheeting I will only complete the tips.
The leading edge has now been finished until I do the final sanding.
Next is the tip sheeting.

With the leading edge planned down to the top sheeting.
It's now time to unpin from the board and have a look at the bottom.
As I suspected🙄 a bit of glue a couple of clamps and a piece of wood should sort that out.
Once dried I can plane the leading edge down to the bottom sheet and then glue on the leading edge cap strip.

Thanks Nigel and Ron, I was trying to keep the wing as original as possible however a two part Wing is the way to go. Leaves the issue of how to achieve the join. Surgery was my first problem that made me think of boxing in the existing braces.
Meanwhile the leading edge has been completed.
The plane is keen to get working
The top looked good but I can feel that the bottom is not right at the tip. This has been caused by mixing methods and not being able to see what is happening to the bottom.

Hi Ron,
I am looking at the options now and wondering if I can use the braces I have already glued in place on the first part of the wing.
In the meantime the leading edge has been plained and sanded down to the ribs ready for glue.

After damping the sheet the glue was applied and then the sheet placed and weighted down and left overnight. Here we are ready to reveal the results.
Incidentally I do find my new steel straight edges excellent for the job of just adding weight.

After a couple of days off from the build here we are back again. I have turned the board around and finished all of the internal bits.
I have decided to glue the top sheet before the the leading edge. The straight edge has now been positioned and the top sheet will be dampened on the top only this will help the bend form and reduce the stresses.
The decision has been made to make this a two-part wing on the basis that if I leave it together then I will have a single piece Wing with the option of taking it apart when I feel it is necessary, best of both worlds, I think.

TE sheeting completed.
I can now turn the board around and work on the leading edge. More to come.

Thanks kc, progress has been stopped by too much thinking. I think I will continue with the build to the point where decision has to be made. Today we'll be working on the TE sheeting.

It's not too late to turn it in to a two piece wing............
This has made me think I think a change of plan is called for. I had planned on a single piece wing as transport is not a problem I was just concentrating on reducing the amount of work needed at the flying field. It has now become obvious that a single piece Wing is huge and there will be a lot of damage caused in the workshop and hangar. I am now exploring the way to make this a two-piece wing.

Thanks guys,
I have decided to keep the two wings separate for as long as possible because this wing is big and will cause handling problems once joined so I have continued on the wing by installing the spars and the root rib after dry fitting this first Wing. The top spars are not glued to the root rib this will allow some flexibility when gluing together the wings.
The next job is to dry fit again so that I can line up the top sheets and mark their positions with straight edges.

If you arrange the postage I will find a suitable box I actually want nothing for it but if you make a charitable donation to your local stroke department it will be relevant in my case.
With regard to postage it is my understanding that the post office will now collect free of charge and postage can be paid for and arranged on line.
I hope it is okay because mobility is an issue for me at the moment. Let me know if you want to do this and I will pm you my address.
