Can it be done without the bar across in the middle? What an interesting custom table leg base. love the tree. Chair selection for the table should be careful to not block the design. Wouldn't a reclaimed wood top be cool with it?
Love the hairpin legs. Great Legs for Your DIY Table. Sources for hairpin (industrial or modern), unfinished wood (wegner danish modern), stainless steel column (contemporary), tapered (mid century modern), and tapered slim brass.
