We have a wood kitchen surface and a pretty large copper sink. The hole is prepared for the sink, which we originally wanted undermounted with a positive reveal.
The idea was that the wooden cutout would be used as a lid to fill the hole when the sink wasn't in use and a cutting or work surface when the sink was in use.
However the copper sink looks much better overmounted. I would still like to be able to place the lid in the sink though, even with the copper rim around, and ideally have it flush with the remainder of the kitchen surface.
My question is, what can I do to support the lid in the sink? Can I tack weld something onto the inner sides of the sink, and if so what can I do to achieve that.If I hammer some kind of studs through into the wood surface, what can I do to seal the object hammered through?
