What magnets for magnetic cavity cover?

[RonC]

Hi All,

For my current build i would like to use magnets for the cavity cover.

I would like to use 4 magnets.

Does anyone know what would be a good size and strenght of the magnets to hold the cover but also not too hard to get is off?

Any experiences with this?

Thanks!

Ron

Nd. They are small and powerful. My fretless has 4+4 neodymiums that are Ø 4 mm. You want to open the cavity, use a plectrum:
