Hi Steve,
I know exactly how it feels when you cannot locate a hard-to-find woodworking plan you need for some special project. A plan for a pie safe is certainly a tough search. But you may be pleasantly surprised like the gentleman who discovered an answer to his search in an obscure place I want to suggest to you.
I believe my best bet might be at http://www.planwoodwork.com No promises, but that other guy found a hefty bundle (actually thousands) of excellent woodwork plans for various units, with colored pictures and simple step-by-step, accurate dimensions for getting a professional look. A little patience will not hurt to easily search through the digital bundle of free plans. You may just find exactly what you've been looking for.
So check up at the following address, Steve, and all I care about is a kind "thank you" mail. Good luck to you.
