hey i was wondering if anybody uses elmers wood glue to glue robart hinges in? i would rather use it than thick ca and or epoxy!!!

twister,
I use epoxy because I know it works. I use alcohol to clean up if I get any drips.

Why not just take two pieces of balsa and 4 hinges, use the wood glue and let us know the results! I've heard of people using Probond and RC56 canopy glue but never Elmers. I've never used Elmers to glue plastic. Let us know the results.

I`ve used mostly Sig-Bond with these for several years and never had a failure yet.

Some of these are larger energetic type models too. My 96" Extra with ST4500 for power was done this way without a hint of a problem.

I have no intention to consider a change from this combination and I am a fairly prolific builder.

Go for it.

Overlooked to mention above - clean-up using a cotton-bud dunked in water and then squeezed out. Simple.

Very successfully used RC-56 in balsa for many years in many planes. The hinge will break before you remove it. Save the epoxy for foam wings.

Never tried Pro-Bond yet. Should work great in foam, but have to worry about the expanding foam clogging the hinge. If just balsa, stay with RC-56. Its made to stick to plastics.

Did as suggested above, took 2 pieces of Balsa, four hinges and Titebond wood glue. Let set over night and pull tested the next day. Wood seperated away from hinge point, barbs on hinges still had balsa attached.

Using on Dynaflite Citabria, has 10 flights and the hinges are tight. (Just checked to be sure)

JimO,
Interesting results, and one I would not have predicted. Just goes to show that sometimes the traditional way isn't the only way. I believe I'll still use epoxy because that is what I'm comfortable with.

I would say something about epoxy being water proof and gap filling, but then I'd just be trying to justify staying with epoxy.

After all if you need to fill a gap installing hinge points your construction techniques aren't up to par!. However I do wonder if moisture over time might cause the bond to weaken?

Oh well, just too satisfied to change.

JimO,

Believe the results. The water based glues like Titebond and RC-56 actually cause the wood the swell into the barbs. There is no gap. Do a search and you will lots of discussions on this.
