Finally had some time to finish the rebuild on the Super Cub. Wife and I have have been in throes of an 2nd floor remodel this summer. Boy do have anecdotes about that - but I digress...

Anyway, Super Cub happy to have rebuilt this little one after I tree'd it. Had an opportunity to walk over to a near by field this evening and put a few winds in her and give it a toss. Delight to see her climb out and fly a small circle. Still, some more trimming and much larger field are required. Hope to get a vid soon!

Hope everyone is having a nice summer!

You're very welcome, sir! And that poor little Super Cub will see the wild-blue yonder soon enough! 

Hi Tom. So as a test, I spread some Tite-Bond on two separate pieces of balsa and let it dry. Then I glued the balsa pieces together with my Hobby Town CA. By all accounts, it was a very good bond. After the CA cured, I twisted the two balsa pieces and the balsa tore before the glued joint failed - good enough for me. 

So based on this, the rebuild process on my Super Cub is moving forward using CA for repairs.

Just wanted to take a moment share this. I started the repair process on my Super Cub. The first picture depicts the damaged wing. It broke off where it joins to the top of the fuselage. So that part where it joins, was still glued to the root wing rib. I wanted to see if I could separate that piece from the root rib so I might reuse it. The glue in this case, was Tite-Bond II.

Somewhere along the line, I learned that you can make fine cuts of soft material using thread. You simply un-spool a piece, pull it taunt and move the thread back and forth in a sawing motion.

So I tried this by carefully wedging the thread between these two pieces and began sawing. I was able to saw in between these pieces in under a minute and successfully separated them. The magic here, occurs not only due to the cutting action of the thread, but also, in this case, due to the heat generated by friction. I believe it was the heat softening the Tite-Bond as I cut, that helped make this work so well.

Now for the "luck part". A couple of months ago, I was working with 2 x 6 lumber and a scrap peice split in a most unusual way. It was so unusual that I decided to keep it because I thought it be useful.

In the pictures below, you can see what I mean. It was this piece of scrap that I used to clamp the wing down to a table with the root rib hanging over the edge so that I could perform the thread cutting technique. Because the shape of the split, it fit the wing ribs almost perfectly so I was able to clamp the wing down with no damage.

So after all this, a question. As mentioned, I used Tite-Bond to glue these two parts together. Wanting to reuse both the part that broke from the fuselage, and the wing root rib, I don't think I can use Tite-Bond for gluing because Tite-Bond will not bond to itself. Any suggestions about what glue might work in this case? CA maybe?

Edit: Did some research on some wood working websites and discovered that CA will bond to old glue. Going to try this on some test pieces first. 

If you're going for max turns, time for a winding tube!!! It'll save the fuselage from a broken motor in the winding process.

Sorry to hear of the difficult removal but glad to hear that your carrying on!!
