One of my friends came to my shop and asked me to make him a pizza serving tray . I cut 19mm birch plywood to desire shape and paint it only with OSMO oil. after a month he send me this picture.
I don't know what happened exatcly , but I think after rounding corners with router , the top veneer layer got weak and detached after a while.
my question : Is the brich plywood an accetable selection for making these types trays ?
if yes , Can Polyurethane color
kind of seal the whole part and privent these types of damages?
