The pic below shows a bridge which I have built for my new guitar project (Prima-R).
The idea was to build a smaller bridge with the aim to slightly decrease the overall mass with respect to a standard belly bridge.
The E to e is exactly as I wanted (56.5mm) but I am now wondering if there is enough gluing surface to avoid potential bridge from popping up. I guess I will discover after stringing the guitar but I would rather avoid this if anyone has a safe minimum gluing area figure in mind based on a 12 gauge strings set.

Thanks for your valuable opinions.
