What's an anepoxy table?
You can buy Hairpin legs on eBay and elsewhere online. Probably obtainable at large DIY's too. Otherwise you will have to make a wooden frame with legs to place your table on. Some folk set the legs in the epoxy resin too. Good luck!
Yes also Hobby Lobby has a great selection of table legs! They are in their hardware section!
Amazon and Etsy have hair pin legs, and Amazon has the 50s style slanted tapered leg replacements.
Your local home improvement store may have some legs too but Etsy, eBay, or Amazon are good choices.
