Fixing the Shoestring

As I mentioned in the last flight report, I popped a leadout and did an inverted flop after a bunch of spectacularly tight outside loops. The controls were jammed, and I freed them and didn't think much of it until I got it home and cleaned it up. The bellcrank gets slightly stuck whenever I pull full Down. I had to use my cell phone camera and a flashlight to see why.

The first pic is the tip of the crank stuck in the hole of the #1 rib. The dark line is the control rod.
The second picture is the whole hole.
 

The bellcrank punched a hole in the #1 rib and it gets stuck in it. I thought about just adding a stop to the control rod to limit the throw. Then I made the mistake of posting that plan on the perfectionists' site, Stunthangar. Not a good way to fix it, the old dudes said, offering no good alternative, even after I asked. But I got to thinking... what the hell, I'll try something else. I don't want to cut open the center sheeting to patch the rib. It isn't much of a hole anyway. Maybe I can reach in with a q-tip and wipe a little CA around the inside edge of the hole to stiffen it before sealing the wing back up.

Anyway, I made a plate out of 1/8" birch that stops the crank in exactly the right place before it enters the hole. It also protects the other side of the crank from ever punching another hole in the rib. I didn't feel like gluing tonight, but I'll add some small braces to make sure it stays in place when I finish it tomorrow.
Here is my fix.
