3D Gluing Robart Hinges

    Hey Fella's,
    So a friend of mine wants to use thick CA to glue some Robart Hinges on his plane. How bad would it be if he did? I've always used epoxy or Gorilla Glue so I don't know.

    Thanks much...

    I have never heard of that before. Thick CA is more of a gap filling glue. I wouldn't trust CA glue to securely attach Robart hinges. I would only use epoxy, though I have heard others use Gorilla Glue.

    Yeah I wouldn't trust it either, just wanted to see if anyone has ever done it and what happen or what the outcome was anyway. Did they hold and for how long. Just don't think they would last is all.

    Gorilla Glue worked great on some I repaired. From what I have read, I would not use CA.

    Wet the hole, and glue with Gorilla Glue.....

    CA on hinges would be a disaster I think. While it might hold good luck getting everything lined up right before it started to set up even with thick. My luck I'd have 1.5" hinge gaps.

    I have heard of folks using canopy glue with good success but I have not tried that as the GG works so well!

  6. I use titebond. Never had one pull out. Easy cleanup. Clean your hinges in warm soapy water, rinse and dry. then install. get a glue gun put some titebond in the hinge hole and insert the hinge.

    FYI: for those who don't know us we manufacture plane kits and have been doing it for over 20 years. www.jtecrc.com

    I have heard other people say tightbond but then I have heard others so it doesn't hold plastic very well.

    Hysol is another good one. Either that or good ol' epoxy, gorilla glue..etc. I've heard of people using CA with good results but I'd prefer to stick with whats generally recommended.
  9. Test it for yourself. If I remember correctly Robart even use to put it on there instructions. I have even used it on flat hinges such as Klett and dubro. See the picture with my post. We have about 12K invested into that plane and all the hinges are put in with titebond ( aliphatic resin).

    Make sure to clean them in warm soapy water

  10. Tightbond or Gorilla glue is what I use as well, the tightbond is much easier to clean up but either one add moisture to the hole, and when it does the wood swell around the barbs on the hinge, I pull tested a couple of them glued in this way about 15 years ago, when I exceeded 50 lbs. of load, the metal pin began pulling through the plastic but the hinge never moved. One of my flying buddies and I cut an installed hinge pin right down the middle and that revealed how well the wood had swelled around the barbs. NOTE: in either application of adhesive, the proper hole size is essential, when I do install these using Gorilla glue I first use a Q-tip dipped in water and slosh every hole prior to gluing the hinges in. As Al already stated, I do clean my hinges in warm soapy water prior to installation.
