Step 7: Attach the Box to the Table Top
The box that holds the sewing machine attaches to the table top using dowel joints. Start by drilling three or four holes along the edge of the table top using a hand drill. Using the hole transfer pins, transfer the positions of the holes onto the edge of the box. It helps to lay the table top and box upside down on a flat surface to do the transfer. With the positions marked on the box, move it to a drill press and drill the holes.
Insert dowels into the holes, and test-fit the joint between the box and table top. If everything is square and properly aligned, glue the joint with carpenter's glue. While the glue is drying, set the table upside down again on a flat surface so that it dries flat.
