Dawn, When I was teaching school, got to see a lot of table legs. Some were fastened to metal brackets, while some were fastened to wood brackets. Both fastened with hanger bolts screwed into legs on one corner, and then fastened to diagonal brackets (wood or metal) with nuts and washers. Being that you are a woodworker, it just makes sense to use wood (scraps of hardwood such as oak, maple or ash) to make your own. The metal ones had to have a slot cut into apron to work, while the wood ones were just screwed on.
