12 ft farmhouse table with extensions - reclaimed wood

I had no experience building furniture prior to this project but I wanted a 12 ft outdoor table and could not find one.  This tables center section is 8 ft and was built roughly following the plans for the farmhouse table.  I added two 2 ft extensions at each end making the overall table 12 ft.  The extensions included aprons so when installed they look to be part of the table.  The extensions just plug into the end apron of the center section with 2x4 oak braces which engage in the apron and under the table approximately 2 ft from end.  There is no visual sagging of the extensions. I finished the table with Sikkens DEK finish.
