Add 1.5” pocket holes to the ends of each board and attach using 2.5” pocket hole screws and wood glue. You will make 2 of these X pieces that will be identical.
Attach the 4 leg pieces to the ends of one X piece using 2.5” pocket hole screws and wood glue. The ends of the leg pieces will be flush with the X piece and pocket holes facing up as shown.
Attach the other X piece to the ends of the leg pieces using wood glue and 2.5” pocket hole screws. The X will be flush with the ends of the leg pieces with pocket holes facing as shown.
Now attach the base assembly to the bottom of the table top. Use 2” Kreg pocket hole screws through the base and into the table top. We used the Kreg Quick-Flip to make this part even easier. There will be about a 1” overhang from the legs to the table top edge.
