Follow the next steps:
1. Cut two pieces of plywood of 300×100 mm. Mark out a gable end from each piece, using the 300 mm side as the base of each triangle and marking the apex 80 mm above the base line.
2. Mark out and cut out two gable supports from the plywood, each piece should be 125 mm tall and 50 mm wide.
3. Measure and cut out the plywood table base, a rectangular piece of 400 x 300 mm, taking care when marking it out to keep the corners square.
4. Cut out 4 pieces from the batten for the table-base edges: two 400 mm long pieces for the sides and two shorter pieces for the ends, 250 mm long.
5. Line up each gable support at right angles to the centre of a short batten so that the edges sit flush. Glue and nail each gable support into position using 30 mm nails.
6. Centre each gable support on a gable end about 20 mm from the base, so that the gable end is on the same side of the support as the batten. Glue and nail them in place.
7. At this moment you should have ready two side sections, each composed of a gable end, gable support and short batten. Prepare the table base by glueing and nailing the long battens along the two long edges of the table base, then fit the side sections to the ends of the base and glue and nail the short battens to the base. The battens will stop food from falling off the table.
8. Cut two 400×180 mm roof panels from the plywood. Glue and nail them to the gable ends so the roof panels meet at the ridge of the roof.
9. Fit and glue the beading to the ridge to stop water seeping into and rotting the roof panels. Secure it with 20 mm nails.
10. Mark the width of the post at the wider end of one of the prepared feet, drill two pilot holes for screws and apply glue to one side. Position the foot against one side of the post so that the long, straight edge of the foot is flush with the post base. Screw to secure it in place.
11. Take the second of the prepared feet and drill and glue it as before. Butt it up against the protruding length of the first foot on the post. Check also that the long, straight edge of the second foot is flush with the post base, then screw to secure it in place. Repeat the process with the other two feet making sure that all the long, straight edges of the feet align. Now stand the post up.
12. Screw an angle bracket onto each side at the top of the post, making sure that the top of each bracket sits flush with the post end. Position the top end of the post in the centre of the table base and screw the brackets to secure it.
As a finishing touch you can put a screw into one of the batten, leaving it protruding by about 1 cm, on which to hang a feeder. You could also paint the table with an animal-friendly wood preservative to make it last longer.
