i used pvc pipe to repair table ring when it broke.buy 2 inch or 2 and one fourth or 2 and one half depending on size of table. Make sure you dry fit first so legs and pvc pipe fit snug under table.Be careful on lenght of bolts so unbrella will fit between bolts when you slide it into base through table top. of course i hope you saved broken ring so you can drill holes in pvc pipe or you will have to line up legs to pvc pipe after dry fit to mark where to drill holes.
