Here’s a quick and easy way to mount small tabletops to an apron base. I use several metal shelf pins with a stud on one end and a flat support on the other end. To install these “clips,” drill a 1/4″-diameter hole for the stud near the top edge of the apron so the flat lip will rest against the tabletop.
I position two or three clips along the aprons that follow the long grain of the tabletop and one on each of the other two aprons, centered in the middle. Leave the long-grain clips about 1/8″ shy of seating all the way in their holes to allow for wood movement. Fasten the clips to the underside of the tabletop with screws.
