This is the table I am currently using.  It is only a four person table, so I might upgrade later to the black walnut table.  The apron is douglas fir, but that is only because I did not have the tools I have now.  One of these days that doug fir will be removed and replaced with cedar, and when that happens, there will be no metal at all on the table.  The entire table is wood (except for the tile).  The top sets on the base allowing it to be moved easily.  It has been through three Navy moves and is still standing proudly.
