An 8" diameter gourd will provide enough room for most birds. A 1 3/8" hole is suitable for wrens, titmouses and nuthatches. A 1 5/8" hole is suitable for bluebirds, swallows and some woodpeckers. A 2" hole is suitable for purple martins and most woodpeckers. If the gourd is thick, you will need to get through the shell gradually with a less aggressive, more frequent pass. Two coats of spray polyurethane each year will help protect your gourd birdhouse from the elements.
Draw the size hole you want for the birdhouse entrance onto the gourd. The bigger the hole, the bigger the bird youÕll attract.
With the 125 high-speed cutter, remove the material for the entrance hole. Smooth the edges with the 952 grinding stone. Recommended speed: 20,000 rpm.
Put 4-5 drainage holes into the bottom of the gourd with the 124 high-speed cutter. This will help keep the gourd dry.
To hang it, put two holes into the neck of the gourd with the 628 drill bit. Run a leather shoelace through the holes and tie the ends in a knot.
