Although I have 4 work areas in my shop my primary building table is the size of a standard 24" wide hollow core door. I have bigger but they always hold too uch junk and get cluttered too easily. The existing "building table" is framed up with 2x12 lumber and I attach an actual hollow core door to the top depending on what I need....fuselage jig....wing jig....foam cutter....or just a flat surface.
