Lay the aluminum out flat and use the tape measure and carpenter's square to mark a rectangle 24 by 18 inches.
Use tin snips to cut along the lines.
Use a hammer to bend down any rough or twisted edges left by the snips.
Attaching to the Post
Using either a hammer and roofing nails or a drill with screw bit and sheet metal screws, securely fasten one 24-inch edge to the post. The 18-inch edge should be flush with the top of the post. Use five nails or screws evenly spaced, keeping metal flat and tight.
Use a hammer and pliers to bend the metal at the first corner. Fasten the second side in the same way.
Repeat step two for the remaining three corners. The metal should overlap approximately two to three inches. Fasten the end securely, avoiding driving nails or screws into your original fasteners.
Things You Will Need
- Lightweight sheet aluminum at least 24 inches by 18 inches
- Black magic marker
- Carpenter's square
- Tape measure
- Tin snips
- Sheet metal screws or nails
- Hammer or drill with screwdriver bit
- If possible, it is simpler to attach the squirrel baffle before installing your four-by-four post in the ground. Try placing it on a picnic table or saw horses.
- Holding the metal for the initial attachment can be difficult. If you are working alone, a pair of C clamps or quick-grip clamps may be useful to hold the metal.
- If you have trouble bending the metal at the corners, a small vertical snip at the top and bottom of the sheet may make it fold more neatly.
- If using screws, a pilot bit or self-tapping screws may pierce the metal more easily.
