My Southern 2 kit by Mark Roberts build


I first wrapped the wing skin around a couple of cardboard tubes from Solar wing coverng.

I did this to train the EPP to curve to this position. IT WAS SCARY TO FOLD OVER, FELT LIKE IT WOULD BREAK, BUT IT DID NOT. WHEW!!!

I then drove to different stores in my nearby larger city, looking for sutiable glues.

I could not find Goop Marine anywhere.

I found a contact cement made by Locktite, and I am going to use that. Label says "Sets in 1 second"

I decided to install two 1/8" x 16" carbon fiber tubes in the top and bottom of the wing spar.

I cut a groove in each edge of the spar, with my rotosaw, so they would be flush with the inside wing skin surface.

I placed the 2 center ribs 2 1/4" between centers, and the others 3 1/2" between centers from each center rib.

I also rounded both ends of the spar, so i could fold over the wing skin smoothly. (I hope!}

In case anyone is wondering, I made a fence for my rotosaw, using spring clothes pins.

I then decided to glue just the front rib tips to the inside wing skin.

I looked like the ribs would have an air gap if I didn't.

I then glued the bottom edges of the ribs and spar to the wing skin.

Looking good BYF!!

So since you are using contact cement, are you having to apply glue to both surfaces?
What is the sure time before you can contact the pieces?

Thanks

Thanks guys,

Yes I am putting the cement on both surfaces, then I press them together, then seperate for 15 mintutes, then attatch very carefully. The contact is instant. No room for error.

Oh, by the way, glueing the wing tips came out so-so in my opinion.

Should fly fine though.

I'm building as fast as the contact cement will allow.

Time for bed now, It's 12:25 AM in Michigan.

I wish I didn't have to spend the whole day shopping, not only for glue, but Christmas stuff as well. (Have to keep the lady happy!)

More tomorrow
