RE: getting epoxy in small areas
This post is not to get a spat going over which type glue to use, but to share an alternative approach. To alleviate the glue in the hinge problem I did a test using wood glue. A test section of rear wing spar and a test section of aileron stock were used along with a hinge glued in place with wood glue. The glue that squeezed out onto the hinge was easily wiped away with a wet Q-Tip. Next day when the pull test was conducted, the wood splintered with hinge attached. The glue joint did not fail. I have since used this method on all non-CA hinge installs and had never a failure.
