Temporary adhesive to fixture control surface hinges (piano) for fitup and drill/cleco/rivet. 1

[booshambo]

We are trying to mount hinges to a control surface and subsequently attach that to mating hinges on a wing in the context of an experimental
(homebuilt) aluminum airplane.

It is convenient to glue one half hinge to the control surface on a jig for positioning, With this fixturing it is then possible to
confirm fit with other parts of the wing, and then to drill and cleco, at which point the glue can be cleaned off.

In the past We have used "superglue" for this, with acetone to remove the glue. This kind of works but is quite fragile (aluminum to
aluminum, in flexible thicknesses).

One nice aspect of a glue that flows (any of the thinner cyanoacrylates) is that it can be droppered onto the joint without disturbing the jig fitup.
Sadly this often makes a joint that is not secure and is still very hard to clean up.

Is there a specific Cyano or a more suitable adhesive for this kind of operation?

Thanks very much.

Cyanoacrylates are the go-to material for this application. Are you priming with acclerators before fitting up the hinge half to ensure a clean and active surface?

 

[booshambo]

Had never considered using the accelerator as a primer. Makes sense. We are doing another setup tomorrow and will try it then.
Thanks very much!

Try it first on something you don't like.

We are very into coupon first - no fear there...

if the idea is that you don't know the final (ideal) position of the brkt because this is a prototype then sure, temporarily position using superglue. Double sided tape would work just as well.

Then once you have a good location (that works with the other side of the hinge) properly install with screws, and record so next time you go straight to the final installation.

Double stick low adhesion tape... or maybe 3M Command-Release double stick tape with-pull-off tabs.

Perhaps 3M has other suitable double stick tape products.
