Having made a breakfast bar i want to add a flap of the same plank either side to make a decent table width. Does anyone know where i can source brackets (collapsible) to support these in the UK? Failing that, i had been considering making some sort of outswinging triangle supports.. but i'd be concerned about not getting the squeeze i want for a firm flat opened surface, and friction damaging the wood would be an issue. Probably there are some sort of spring-loaded roller/plate kits i might use there..?
