Martin with alloy soundboard

[Len Biglin]

Hi everyone , This is a Martin with an aluminium soundboard , the bridges on these tend to let go . This one has been reglued 3 times , taking care to scuff the metal and using hi strength epoxy . Im in Australia so returning to factory is not an option . Any ideas ?

The bottom half is at the CNC shop.
