Hi Lee, this is the setup I,ve used for the last twenty. I built simply with steel legs so that I could size them to the exact height needed since I use a wheelchair all the time. The length of the main table is about six by three feet with a wing table on the end that proide another 18" or so in length but more importantly the wing table protrudes out in width also 18 inchs. This L shaped provides an amazingly wide variety of airplane that can be worked on at the table. It is toped with Cellotex half inch and sold in four by eigtht sheets.
I have found memories Lee of working in my room in the fiftys just as you are and even in sixties, working on a foot locker at the barracks in Germany
