You’re taking a patio table and putting it in your dining room? Is is metal? Does it have a pedestal base now? Does it have glass or metal mesh in the middle?
Im trying to determine What one can fasten new legs to, and where they can be fastened.
Do you mean the round base that holds the umbrella under a table? If so, here's instructions that should help you. Wishing you the best.
No, the actual base that holds both table top and umbrella
i am picturing designing/making one from metal plumbing pipe and pipe fittings. Could be designed for a round or rectilinear top. Only drawback is that the component costs start to add up pretty rapidly.
