Thanks Fred. I have a table that we built to store such items, ...and I thought we had a good place to store the panel boards too until it got filled up with rolls of piece goods and other stuff. Now the panels get stuff piled on top of them making it a chore to get at them or to put back a piece. Hence the reason for the shelf. FWIW, below are some pix of my table during final construction.

Kris, if you are limited in space, consider using a folding ping-pong table.
