Default Cloud ranger build by newer builder

Currently building as my second model, per the wing construction directions it only has the rear innermost bottom sheeting going on prior to installing the dihedral shear web, do we just take the chance floating the brace to accommodate for the front piece of sheeting or do I partially glue the front sheeting on to fit the brace in and then finish attaching at the appropriate time? Can attach pics if needed

It's hard to imagine, I don't have the kit, also probably why others haven't responded. Looking at the downloaded pdf instruction manual, I'd say you should just follow the instructions. You're not "floating" anything. Normally, you build one half, then build the other half. Sand the wing root so that leading edge, trailing edge and spar all match up, then glue the dihedral brace and wing halves together. Hope this helps. Looks like a nice kit.

Photos are almost always helpful. I've had planes where the instructions didn't seem to make sense until one step or another and then it just kind of clicked and I could see how it worked. You may also find threads on other forums.
(Edit) LOL, just went to look at the rest of the 1/2 a threads and saw that you had been to the build thread for the same kit just below.

A question for those that have built any of the Herr kits that call for Nylon tape to re-enforce the wing joint. Sig doesn't give any real info about the tape referenced in the kit. When I asked they gave me a part number to sell. Is it just Nylon strapping tape that is glued to the wing, or is it something special that is wetted out like fiberglass? If it is strapping tape I am just going to purchase a role from the local hardware store, otherwise I will have to figure something else out. The idea of just glue holding the two wing halves together I must admit is a bit scary to me. I have read others doing it and using epoxy but I must make the safe assumption that they are more experienced builders/fliers and may not be as hard on their plane as me.

Goldberg used to have some really nice nylon tape, perfect for small models. You might be able to find some on the internet. But, some fiberglass tape would work just as well. Fiberglass cloth, is available everywhere. Just find some and cut a strip long enough for your project.

The purpose of the tape is to strengthen the point where the spars join at the dihedral joint. This is usually a butt joint which is often considered the weakest sort of glue joint. The tape spreads the tension on the lower spar joint across a much larger area creating a stronger joint. The fiberglass or nylon is usually wetted out with epoxy or resin since this gives a good bond to the wing structure. You can use a playing card or old credit card as a squeegee to avoid leaving excess resin on the plane. For larger airplanes the strength gets to be a more significant issue but for a half A you can still build pretty lightly.
