Piezo install on classical guitar bridge

[Romeo Suave]

I am in process of building a classical solid body guitar.
It will use a classical bridge made out of Kauri and piezo pu.
The Piezo uses 3-20mm disks for the pu. The company selling them recommends that they be as close to the vibration source as possible.
Their answer to my question I think was deliberately vague since they do not want to be held responsible for the outcome of my install, nor should they be held responsible since their product is meant for acoustic classical guitar. what I am thinking of doing is simply drilling 3-20mm holes in the bottom of the bridge till it just kisses the slot, will be using bone, then using epoxy since I assume that epoxy will not dampen vibration. As always in my life any of this is a learning experience, I hope you will have comment, advice, experience, knowledge (did I forget anything) that will help me make this work. Even if it is confirmation that my approach has merit, but there may be better ways?

Hi Romeo.
Don't worry about drilling holes. Just affix the disks below the bridge. You can use superglue (CA/cyanoacrylate), epoxy, silicone adhesive (make sure it's nuetral cure) or hot melt, just make sure it's as thin an application as possible. Trying to make the disks integral to the bridge is just asking for trouble, and probably won't buy you any advantages.
