How to Make a Copper Trellis How to Make a Copper Trellis
A copper trellis is both useful and eye catching. It’s sturdy, as copper outlasts most wood trellises, and it looks better with age, particularly as it begins to oxidize. So if you’re growing vegetables or flowers, copper trellises maintain and support your garden well. Best of all, if you follow a few basic steps, making copper trellises is a quick and easy task to accomplish.
Step 1 – Cut Copper Pipes
The first thing to do is cut three 10-foot ¾-inch copper pipes into 12-inch separate pieces, which will give you the 30 12-inch ¾-inch copper pieces you’ll need. You will use these copper pieces for the parallel walls and the horizontal slats for your trellis. After you have sized and cut your copper pieces, you can then begin to assemble these parts into your trellis structure.
Step 2 – Clean and Fit Pipes Together
Clean off the tubing and fittings so they have no particles or dust. With your flux brush, add flux to the inside of one t-shaped fitting, and then attach two 12-inch pipes into each end. Once finished, you’ll have an “L” shaped piece. Add flux to another T-shaped fitting and affix this to the opposite end of the horizontal pipe and connect another parallel pipe, which will give you a “U” shape. Each copper fitting should now have one opening left at the bottom where the next two parallel pieces will go. Keep fluxing the copper fittings and affixing the pieces together in this way until all pieces are connected together, which will create what looks like a mini ladder.
Step 3 – Solder Pipes to Copper Fittings
Now it’s time to do some soldering, so lean your trellis against a sturdy wall or a secure place. Before you start to solder, put on your safety glasses and welding gloves. Work from bottom to top, unwrapping about 10 inches of solder and holding the tip of the solder up toward the seams of the copper pipe and fittings. Light your propane torch and warm up the pipes and copper fittings. Be careful to not put the torch’s flame too close to fitting joints where flux was brushed on, as it can be easily burned off. As a general rule, hold the torch back about 7 inches away, and only a tad above the joint’s seam. As soon as the seam is hot enough and the flux has bubbles, hold the solder to the fitting’s seam and let it melt evenly over the joint. Keep soldering until every fitting joint has been bonded together. Before putting up your new copper trellis, be sure it’s all cooled off.
You now have a beautiful and strong addition for your garden.
