Gotta get that support in!

First job (after removing the hinges, clasps etc.) is to glue a strip of wood just inside the lid - this will be the end of the box that will support the tines. This small strip of wood give the screws something to bite into …. so, so, necessary as there will be a whole lot of tension created by the spring of the tines. I'm only writing this 'cos if you don't remember to do this at this stage you can't go back and fix it ….. you'll have to throw it in the trash.
