Speedracer, I will see if I can get more CA under that glass area that has air under it. I like the idea of extending the CA out to the wing mounting joint. I already have dents near the rear hold down bolts from test fitting.
Can I reinforce that wing mounting saddle area with only thin CA and no glass? Kind of like reinforcing a screw hole, or control horn with CA?
Just rub the CA on with a rubber gloved finger?
As a couple of guys said recently _ _ _ I am the only one who does not understand.
I cannot figure out what CA has to do in this case. Glassing has the resin do the binding to the substrate.
The glass cloth has to have enough transparency for the resin to go through. I do not use resin; I use genuine aircraft dope and the application is identical. The material has about 80 threads per inch leaving lots of air space between the threads for the binding agent to go through to the frame.
CA has its use for tacking and is easy to take apart (weak joints) and also useful for ARF / RTF models.
I can see making the wood harder with impregnated CA if the required quantity is small (CA is very expensive). For strength I use wood glue and fillet the joints.
This looks like not enough resin was used in some areas or was not fluid enough to go through the glass. Applying CA as a repair may help; nothing to lose.
