What is the best glue to use on Robart hinge point hinges? I usually use epoxy but I found out the epoxy does not stick to the plastic hinge.

Thanks,
Tony

Dont understand that. I use epoxy, sticks fine for me. Are you using enough? I have heard of people using gorilla glue, I wouldnt though. Its hard to control the foaming. Others have used titebond wood glue. I "think" I did that once, cant really remember. I guess it worked ok. I havent had any hinge problems with my installations. I have had a few arf pre-glued hinges come out.

Previously I used PICA's Gluit 2-it (Acrylic Copolymer Emulsion) which was fantastic for bonding most plastics to wood.
I have not yet found a really good substitute for this glue. In the meantime I use polyurethane glue, e.g., Gorilla Glue.

If anybody out there knows about a source for Acrylic Copolymer Emulsion glue please let me know.

My method is to use Gorilla Glue, this glue spreads out and anchors the hinges in place. I'm flying also up to 100cc aerobatics and there you need something what is proven and secure.

With a small stick (longer then a toothpic[8D]) I drop some in the hinge hole and cover the inside of it. Then I cover the hinge and put the hinge in the hole. The hinges are oiled with light oil. After a while the Gorilla Glue starts to expand and try to cover your hinge - a Q-tip with acetone will remove quickly without smears the glue.

You have to have an eye on it for the first 30 to 45min after that it's fine. Some guys cover the trailing edge (wing) and leading edge (control surface) with blue masking tape --- I don't.

The advantage is the expansion of this glue in any direction. the epoxy just goes with the gravity. Disadvantage : It takes just a little more time and effort BUT it's worth it!

we have been using loctite sumo glue, like gorilla glue but you have foam in about 8-10 minutes, 30 minutes you can handle the part. push your hinge through a piece of trash bag then stick in the hole the bag keeps the foam out oh hinge but oil the hinge too! when cured tear away the trash bag.

Pacer hinge glue works well when gluing hinges into wood. Other than that I use 30 min epoxy with micro balloons. Make sure you wash the hinges with good old soap and water first to remove all parting agent or oil from your hands. Then I use a drop of oil in the hinge pin. Drop glue in hole, thinnly coat hinge and install. Clean away any excess with alcohol.

I use 30 min epoxy with milled glass fiber added as a filler/binder. You can get it from RC City. Works like a charm!

Hi Tony I've been using hingepoints for years as you know. I wash all my hinges first with denatured alcohol. I rough up the surface on the hinge point with sandpaper. I apply vaseline with a toothpick on the hinge joints. Apply epoxy with a tootpick in the drilled hole and insert hinge. Any glue that oozes out is cleaned with deantured alcohol. I've never lost a hinge in over 30 yrs.

Thanks for the help guys. I will stick with epoxy but I will clean the hinge and hit it with some sandpaper first.

Thanks,
Tony
