2. Make the cleats 3/4" × 2" × 15" and nail the top to them. (See the
drawing for the position of the cleats.)
3. Rip off the tongue edge and plane it so that the top is exactly 18"
wide.
4. Turn the cabinet upside down on the floor and fit the swing tops.
Hang them with a pair of butt hinges opposite the ends of the cleats.
5. Make a T-brace with a nailed cross lap joint from two pieces, one
being 13-16" × 2" × 14", the other 13-16" × 2" × 16-1/2". The long edge
of the T and the leg must be bevelled 13-16" on one side. Fit and hang a
T-brace with a pair of butt hinges on each side of the swing tops.
6. Make two brace cleats and fasten them to the ends of the cabinet, so
that the swing tops are held level and even with the top of the cabinet.
