This is a sketch of an 250 mm (about 10 inches) lutrin, with all the needed sizes of cuttings, all parts are listed, so It's easy to reproduce.
Some parts are a little too long, so it can be cut afterwards, more. easy gluing and finishing (but takes more time).
Sorry but the page is a little greasy, workbench notebook
