This design is about as simple as it gets, but I think the proportions came out very well. Something most people don't consider is that once a table is surrounded by an army of chairs any fancy legwork, pedestals, stretchers, etc are often hidden, but don't let that stop you!
This was my first experience with Sipo, (Entandrophragma utile), a mahogany look alike and it behaves like a good quality African Mahogany with the quarter sawn parts going very ribbony, other parts had a bit of pomelle figure. Here's a shot of the layout for the top, with paint thinner sloshed on it.
I used a different method for attaching the cross members by stitching them to the side rails with biscuits. I figure the 5 biscuits, which equal about ¾ inch in combined thickness, ought to do the job and is likely over-kill.
This was done as a sub-contract for another shop that I've worked with for years. Here's the completed table, minus a finish, so what you are seeing is thinner and some pretty heavily photoshopped images.
