Hi Ernesto, thank you for your inspiring comment.

There are hardwood ledges along the top (and also bottom) edges inside. This made it possible to use screws with a little distance from the edges and round them comfortably (look to the foto:).

Our playing sufaces are glued and srewed. The screws act as stabilisators, because pure wood glue does often not resist harder playing practices. There are theories that a combination of screws and silicone (removable) between playing surface and corpus could be perfect.

We will use stripes of a rubber mat, which is made to put it under washing machines.

I know. But there are so many different requirements depending on the preferred sound-character and even haptic feedbacks - it is almost impossible to recommend any maker or model for everybody.

Many spanish cajones as well.
