Pretty classy Tom.
Vic you can glue in place using silicone. 3 or 4 drops will do. The silicone will allow wood movement.
That's very nice Tom. It reminded me that I have got quite a few of the Ceramic Plates somewhere and I may just do a few of these for Christmas. Did you glue the plate in position ? If I remember rightly I done one a few years back and glued the plate in and after a while the wood must have moved and the plate cracked.
