To build a cattle chute, first set two 8-by-8-inch anchor posts 22 inches away from each other. Use post hole augers and a tamping rod to set the anchor posts about 3 feet into the ground at the appropriate site. Secure 4-by-4-inch boards to the posts at ground level between the two posts. Place two 4-by-4-inch boards 23 inches above the first cross post and at the very top of the anchor posts on the front of the posts.
Pre-drill holes into the posts and boards to prevent splitting the wood, and use 1/2-by-14-inch bolts to attach them to each other. Secure a 4-by-4-inch board at the top of the right post so that the bottom of the board sits about 10 inches from the ground level board on the fixed side of the chute. Secure a 9 foot 4-by-4-inch board at the bottom cross board about 10 inches away from the mobile side of the chute.
Use an 8-inch hinge to secure a 4-by-4-inch board at the top of the right post, leaving about 2 1/2 feet of board above the post for use as a handle. Use 7 inches of 2-inch wide strap iron on each side of the handle to fasten the left post to the handle. Pre-drill through the strap iron and the board, and then secure a 1/2-inch bolt into each piece.
