Build a Copper Pipe Trellis

Simple techniques transform plumbing pipes into functional garden structures

I appreciate the cool shade of the towering fir tree trees in my suburban Portland garden , but my peak do n’t . Therosessprawl toward the east in search of morning sun , and thedelphiniumslean longingly toward the luminance . To stomach my wandering climbers , I wanted a trellis that would be ornamental in both summertime and wintertime . I searched without success through catalogue and nurseries for unworried , long - hold out structures until , finally , I saw what I want in a local garden — a simple , but big , freestanding , copper trellis .

Copper appealed to me because it is so decorative . After a season in the elements , its vivid color weather condition to a deep , warm brownish thatblends nicely into the garden . As the years pass , oxidisation slow buff the Robert Brown to a soft , muffled leafy vegetable .

To plan my trellis , I sketched a sample , and usedbambooto build a exemplar . Then I moved on to using copper , and with avail from my brother , Terry , I ramp up a trellis tumid enough — about 20 in square and 4 feet high — to rail a mature rose . That was just the start . Now I ’m hook on bring in copper garden social structure . I have several dissimilar trellises , anarbor , and lots of thought . The techniques I learned while building the treillage can be used to create just about anything . But it all get with this simple-minded , basic body structure .

Copper is easy to ferment with , too . A few simple dick — include a pipe cutter and soldering great mullein — are all it consider . Using soft , well pliable copper tubing to make curves , assorted distance of pipe for full-strength section , and T - shape and 90 - degree elbow fittings to join pipes together , building a garden structure is as easy as playing with Tinkertoys . My first trellis took just about three 60 minutes to make . The textile are inexpensive , too — my homemade trellis cost about $ 30 , eject tools .

Cut the copper pipe to length

The first step is getting the materials ready , and that have in mind using a pipe tender to cut the copper color pipes to size . position the pipage between the tool ’s press clipping rack and its rollers , so that the cutting wheel hit the organ pipe where it should be cut . Turn the set screw to put pressure on the pipe . Keep the imperativeness gentle — too much can crush or kink up the tobacco pipe . Rotate the cutter around the pipe doubly . This first cut scores the atomic number 29 . Tighten the set shag a small more , and revolve the cutter twice around the pipe again . Repeat until the tobacco pipe has been reduce through .

Bend and cut the curves

For the curved shape , I apply copper icebox whorl instead of standard plumbing pipe . It ’s flaccid and crouch more well . It come in a roll , and I simply uncoil some , amount along the curve and cut off 17 inches . With soft tubing , it ’s even more important to make the cuts mildly . Do n’t straighten out the tube while measure out or cut ; it may crimp or dent . Once I ’ve trim down the piece to distance , I bend it gently to a anatomy that is almost a quarter circle . Then I hack and bend three other art object to match it .

Clean and flux the pipes

After cutting the pipes , I use a nylon or metal cleansing launchpad to scour out any oxide from the ends of the pipe . Clean at least an column inch at each end .

Then , I don a span of latex or rubber glove and set up in a well - ventilated , brilliant work space to avoid fumes from the solder and flux . Brush a thin coating of solder flux density - a substance that avail make strong bond when soldering most metal - onto the end of any pipe that is to fit into a T - shaped , elbow - shaped , or other fitting . That means 12 column inch of flow both ends of most pipes .

Assemble the base

I start at the bottom of the treillage , fitting the top end of the four longest pipes into a metric ton - shape fitting . They should conform to neatly . I connect short , vertical art object to the opposite side of the fitting , create a pole about 38 inches long , with the thymine fitting near the middle and an 18 - column inch , horizontal bar to link two of the perch into heat content - shaped fabrication . I place reducer - metric ton fitting at the top corners , and link the two pieces with the 2d distich of 18 - column inch , horizontal crossbar . To help coordinate all the pieces , I mark a 20 - in lame on the service department floor , and utilize it as a guide for the foundation of the trellis . Use the diagram on the confront page to guide assembly .

Add the domed top

Because the square top is composed of so many short lengths of tube join with so many appointment , it ’s easier to form on this slice separately on a flat surface . To make the top , I flux the ends of each pipe and assemble four identical pieces , each with two 3 - inch lengths of pipe joined by a tonne fitting in the midsection . Then , using the cubital joint - shaped fittings , I conjoin the four straight pieces into a lame . The root of each T meet should face out for link to the four twist piece that link the foursquare to the rest of the social structure ( see the drawing at right ) . The other end of the curving piece tally onto the small possibility of the reducer T try-on on the al-Qaida . I do n’t vex about take in the dome consummate at this stage .

Solder from the bottom up

I normally turn the soldering over to my brother , Terry . He ’s an expert . I ’ve done enough , though , to know bonding takes drill . I also do it this project is very absolvitory , and that it is easy to pass over off spare soft solder with a dampish , cotton cloth .

Wearing his rubber glasses , Terry ferment from the bottom of the treillage up , squaring or square away each joint before applying solder . When the joint depend dependable , he uncoil an 8 - inch length of solder ; this keep his hands off from raging pipes and the torch flame .

Then he get down the propane torch and start inflame the area he require to solder . He moves the blowtorch back and forth evenly across the meet , never aiming it directly at a join — it ’s too easy to burn off the flux . Flux is essential to a dependable bond , so if he does burn it aside , he lets the joint cool , clean the parts again with the scouring pad , reapplies the flux , and try again .

When the magnetic field starts to bubble , the temperature is just about right . He gives it a little more heat , then touches the solder to the joint ; it dissolve on contact and flows swimmingly into place . Any excess is wipe away . Pipes should always be wield with care — they can be very hot , even a foot or two from the fitting . The trick is to turn slowly until you get the feel for it . It is n’t necessary to make the joints watertight .

Square off the dome

Once the just and horizontal pieces have been soldered , adapt the curved pieces and the square top . Check by eye to verify the curving objet d’art are arranged symmetrically and that the square top is parallel with the ground . After we correct all the pieces , Terry solders the dome articulatio by joint , check to make certain that unsoldered pieces have not shifted . Once he ’s finished , I use a stiff wire brush to clean house any excess solder and flux off the joints .

I like to let the fuzz geezerhood of course . But if you could not wait for the verdigris coating to appear , a false verdigris paint will give it an aged look .

Move the finished trellis to the garden

fuzz body structure are well establish in the garden . I take a 3 - foot length of rebar and drive it 18 inches into the ground , then dislocate the copper piping over the rebar . That ’s all there is to it . There ’s no need to pound in a piece of rebar for each of the four legs ; two lengths of rebar fitted to two leg of the trellis should well concur the social system in place .
