Hi Frog:

I use "pinned" hinges as well since they put less stress on the servos and allow more freedom of movement.

The down-side is the CA glue getting in the hinge when you insert them and locking or binding them up.

A trick someone showed me to prevent the CA glue from getting into the hinge is to take a toothpick.... dab some vegetable oil on the moving part of the hinge....work it in by moving the hinge back & forth.... and that way there is no where for the CA glue to go since the pin part is already filled with a drop of vegetable oil, which the glue can't stick to.

A little "veggie" oil (I use olive oil) goes a long way.

If you accidentially get some oil on the flat part you want to glue..... simply wipe it with isopropyl alcohol on a rag to clean it off.

This way I can put a drop or two of CA (I use medium viscosity super glue (CA+) rather than the thin CA) in the slot before I insert the hinge, and if a little glue gets "squeegeed" on to the pin part of the hinge... just wipe it off & work the hinge a few times as the CA dries.

Hope this helps with your pin-hinge.
