Gorilla Glue for CA Hinges
I don't know if anyone has tried this. I am sure they have. I can't be the first.
Personally I hate installing CA hinges. They never seem to hold in well. I do all the tricks like open the slot a little more. Use the hinges with the split in the center to let the glue wick in better, but still they do not seem to hold as well as they should. Well this weekend I was building a 27% H9 Cap 232. It is the old Alitallia one. I was out of Robarts and wanted to get it going so I decided to use the CA hinges. As usual when I installed the first aileron and pulled on it hard to check it, it started to pull out. It took some wood with it and I could see the glue only soaked in about 3/16 of an inch. I had just bought some of the new Quick Cure Gorilla glue so I figured I would see how that worked. I took a block of balsa and cut 3 slits in it. On the first I used CA. On the second I used Gorilla and only stuck the hing in about 1/4". On the 3rd I used Gorilla and put the hing in the correct depth. The method I used was to dip the hing in water. Slide the hinge in the slot to wet the wood. I then removed the hinge and used an epoxy brush and spread a thin layer of Gorilla glue on 1/2 of it. I stuck in in the slot and wiped away and excess. The Quick Cure only foams for a few minutes, so cleanup is easy. I waited 2 hours and then grabbed a pliers. The CA pulled out fairly easy. The Gorilla hinge that was only in 1/4" pulled out far harder and took a lot of wood with it. The last one that was in the correct depth is still in the block. It would rip the hinge appart before it would pull out.
I ended up putting all of the hinges in the same way in the plane. It worked great. I just glued one side at a time just like a Robart hinge. That made it so easy. And I know they will never pull out.
