Step 3: Laying it out
Once the pieces are cut, label them alphabetically so that they correspond to your diagram. This will help keep everything in order. Now you're ready to start building.Step 4: Building the arbor
Start building the arbor from the inside out. Starting with the inside pieces, simply brush the epoxy glue on the outer rim of each copper pipe, and then attach it to the adjoining piece. Once the center is done, begin building from the bottom up. It takes a while to glue everything together, so be patient with this project. Using the same method, finish making the two sides of the arbor. Then make the top. The arbor will seem a little tall, but remember that you're going to sink it in the ground about 18 inches.
Step 5: Putting it up
To ensure stability, dig the holes where you want to put your arbor before you sink it into the ground. Then check for straightness with a level. Place the sides and attach the top of the arbor. Do this using the same procedure you used to build the sides.
Copper will weather with time and take on a beautiful green patina. If you want to quicken the process, clean the copper with steel wool to get rid of any leftover oils.
Plant some beautiful vining flowers such as clematis, honeysuckle or even mandevilla. In no time, these flowers will spill over the arbor, giving you a wonderful entryway to your garden.
