How to Make a Wide Grapevine Arbor

Cut down the four 2-inch-by- 6-inch-by-10-foot boards so they have a length of 118.5 inches. Nail these boards together, creating a 10-foot square. Nail in two 4-inch ring shank barn nails to each corner.

Nail four 4-inch spikes to connect 4-foot long 2-inch-by-6-inch braces to each side at 45-degree angles on each side.

Drill holes to create a grid made of metal conduit tubing. Drill a 1-inch hole 15 inches away from a corner on the 10-foot square. Repeat six more times, spacing them 15 inches apart. Repeat on the opposite side.

Decide where you want to place your arbor. Measure out where you want to put your posts. Since you are creating a wide arbor, decide how wide you actually want it to be. Mark off the spots where you will dig post holes. Make sure the spots spaced at an equal distance.

Use a post hole digger to create holes in each spot. Holes should be between 24 and 36 inches deep. Do not put any soil back into the holes.

Place each of the poles in the ground, tamping the soil around them with a shovel until the pole is rigid. Make sure all the poles are the same height, especially if your ground is uneven. Saw off the tops to make them even if need be.

Nail the 2-inch-by-4-inch-by-12-inch boards so they sit across the corners of the 10-foot square. Saw them flush with the 10-foot square. Put the 10-foot square on the tops of your poles. Use the eight 2-inch-by-6-inch braces to create diagonal braces. Place at 45-degree angles and nail to both the posts and the 10-foot square to secure it.

Drill 3/16-inch holes into the 2-inch-by-6-inch boards. Drill one hole at the midpoint on the board and then two holes on the other side about 1 1/2-inch from each edge. Install lag bolts with washers with a wrench. Attach to the poles with the wrench using lag bolts and washers.

Add conduit to the holes to create a grid, pinning it in with golf tees.
