I have had great success with poly probond by elmers glue for installng the robarts all the way up to 35% planes never a problem . It is very easy to install them you just wet the hinge with a spray mist of water and use a little probond on the barbs it expands in to foam or wood as it dries and yo dont have to worry about gumming up the hinge point as it comes off very easily with a exacto knife around the hinge point after glue is dry it takes about 10 hours to set up completly so you have plenty of time to get everything correct .
