Bridge minimum gluing area

Post by Valben » Tue May 05, 2020 4:28 pm

Hi everyone :-)
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.
Valter

Only one way to find out! :mrgreen:

PS: the top bridge looks nicer.

Nah don’t listen to him!

Trevor Gore in the book suggests that a SS bridge should have a minimum footprint of 3750 mm squared but that doesn’t leave much room for intonation. Thus roughly 160 by 28 is about right.

I’m sure he knows what he’s talking about.

Cheers Dave

Thanks for the comment Dave.
The bridge Martin doesn’t like is about 3950 sqmm ....so I guess I am going to take the risks. Cheers Valter
Oh, I have got the books few weeks ago and I am slowly going through the theory volume now.
