Birdhouse Entrance Hole Template, 5 Sizes for Bluebird, Wren, Chickadee, Nuthatch, Router and Drill Guide

The right entrance hole decides which birds move in. This template gives you five exact sizes in one plate, with the species engraved under each hole, so you never have to look up a chart or hunt for the right Forstner bit again.

SIZES AND SPECIES
- 1-1/8": Wren, chickadee
- 1-1/4": Nuthatch, downy woodpecker
- 1-3/8": Tufted titmouse
- 1-1/2": Eastern bluebird, tree swallow
- 1-9/16": Western and mountain bluebird
These are the commonly recommended sizes. Guides vary slightly by region, so check your local bird society if unsure.

HOW TO USE IT
- Router: clamp the template on the front board and cut with a pattern or flush-trim bit with a bearing. Cut most of the waste first with a drill or jigsaw, then clean up with light passes.
- Drill: use it to mark the exact circle and centre, then drill with the matching bit.
Cross marks around each hole help you centre it on the board.

SIZE
314 x 118 mm (12.4 x 4.6 in), 10 mm (0.4 in) thick. Router bit and clamps are not included.
