For storage, unfold the box and lay flat or support firmly against a wall to prevent plywood from warping. Fold door down against the base base and pile together with the top and stacked drying racks on top of the box panels.

Letter to the Readers
In some of my recent woodworking articles, I have mentioned the pleasure I experience when using the silky, rosewood-handled try square that I inherited from my grandfather. I suggested that readers buy a similar tool, new or used, at an auction or yard sale. Well, I've just learned that rosewood is one of several tropical rain forest trees being over-harvested in the wild, to the point that they have become seriously endangered. Others over-harvested woods include: ebony, roko, padauk, and true mahogany. Coincidentally, all these woods — used for ornamental inlay work and musical-instrument finger boards, as well as fine tool handles — contain toxic phenols and are best not worked by amateurs.
Teak, a tropical (though not strictly a rain forest) species widely used for outdoor furniture, is also endangered in the wild. However, most raw boards and teak products on the U.S. market are from plantations (and have been in existence since the days when teak was used to deck sailing ships) and are now being certified by several international conservation organizations. Hopefully, rosewood and other endangered trees will also come under cultivation or controlled harvest — providing cash incomes to people who are now burning the rain forests for subsistence agriculture. Till then, to do my small bit in reducing the total demand for these endangered woods, I will not buy rosewood, ebony, etc., as raw stock or in a finished product, new or used; I both regret and retract my earlier recommendation. Try squares come with American walnut and other type handles, and readers wanting to work with dense, easy-working but common domestic woods having all the character of an exotic, might look into the Texas Mesquite.
