I'm installing Hinge Points in my H-9 CAP 232 ARF (72") and I have read some threads suggesting using Pro Bond glue - my question is, do I have to be concerned with keeping the Pro Bond out of the working parts of the hinge?

I use epoxy, but keeping the glue out of the hinge is the same problem.

I use Vaseline. Bend the hinge one way, and dip it into the Vaseline then bend it the other way and repeat. Some people use a heat gun to melt the Vaseline into the hinge, but I find it works OK as long as the hinge is covered completely..

Then, when you insert the hinges, the Vaseline stops the hinge gluing together and it also lubricates it for use.

You should insert both sides of the hinges at the same time and work the hinges carefully a couple of times before it sets, so it aligns properly.

I use pro Bond for hinge points. Yes just like all the others, you have to keep it out of the hinge.
I put a very small drop of oil on the pivot of the hinge.

You have to get the feel for how much pro bond to use so it don't expand too much.
I like it because it completely fills the hole. Don't forget, we are putting a tapered hinge point into a straight hole.

Here in Florida, I have never found it necessary to use any added moisture for it to cure.

I have even used it on rather thin edges as opposed to a foam wing, and have found it to work very well.

Do a test piece and see how it forms itself around the hinge point.
