How to attach table leg without metal bracket?

There are a few different ways that you can attach table legs without using metal brackets. One way is to use a strong adhesive. Another option is to use screws and plugs. And finally, you can use dowels.
If you decide to go the adhesive route, we recommend using a product like liquid nails or gorilla glue. These adhesives are extremely strong and will hold your table legs securely in place. Just apply a generous amount of adhesive to the underside of the table leg and then attach it to the tabletop. Hold the leg in place for a few minutes while the adhesive sets.
If you decide to use screws and plugs, you'll first need to drill a hole in the tabletop. The size of the hole will depend on the size of the screw. Once you've drilled the hole, insert the screw and then add a plug to cover the hole. These plugs can be made of wood or plastic and can be painted to match the color of your tabletop.
Finally, you can attach table legs using dowels. This method is similar to using screws and plugs, but dowels are inserted into pre-drilled holes and then glued in place. Once the glue has dried, the dowels will provide a strong and sturdy connection between the leg and the tabletop.
