In addition, not all dovetails are created with exact same angles. If too loose, add and glue shims for a snug fit. If too tight, try to spread steel but still maintain a snug fit.
It is the bottom plate and screws which provide the strength needed to the legs. Many older 4 leg bases have broken screws which originally fastened the hub bottom plate. It is important to remove and replace those screws. Drill a 1 1/4" or preferably larger hole, and glue in an hardwood Hard Maple dowel rod. Purchase the Maple dowel rod first, then the drill bit to match the dowel rod. When glued and dry, drill a correct size pilot screwhole to fasten the bottom plate. Warning, a screw sized dowel pin is the wrong thing to use for a repair.
