CA hinges installation

[Bill Carpenter]

Another suggestion FWIW, if you have a foam wing core under the balsa 
sheeting and glued to the trailing edge, use foam friendly CA.  It will not
eat the foam if it gets in that deep.  Also, some people either drill a hole
in the center of the slot to allow CA to go deeper into the slot at the
center, or some CA hinges come with a slot in the middle of them to allow CA
to go in the slot deeper.

Xavier-
I have used a crayon from my sons toy box, sharpened, and drawn along the
hinge line.  This not only serves as an alignment point, but also as a
release agent for the glue.  I guess I should also note I haven't used that
method on most of my planes ( just wicked in CA at the hinge line, let dry,
and flex vigorously back and forth ) with great results too.  You shouldn't
worry too much about making the hinge stiff - just be sure you are using
THIN CA!! :-)

Hi guys,

I am about to install the CA hinges (fiberglass) on two of my winter
projects and I would appreciate any recommandations on the proper procedure
to do it. I have the tight slots done. I am worrying about the glue making
the hinge stiff. How do I ensure the glue doesn't go in the flexing area ?

Note that these are 2 sport planes that I am using to improve my building
skills before moving on to pattern plane building next year. I have been
flying second hand pattern planes.

Thanks

Xavier
