Pipe frame, about the wire netting
3. Create remaining frame arches
Bend and fit the remaining two pieces of flexible pipe in the same manner as described in step 2. Fit the remaining two pieces underneath the first two. Tape all meetings with Polyvinyl chloride. A common thermoplastic resin, used in a wide variety of manufactured products, including rainwear, pipes, garden hoses, phonograph records, and floor tiles. adhesive tape.
Did You Know? Water goes through water pipe, and cables go through conduit pipe. The diameter of conduit pipe is taken from the outside of the pipe, where as the diameter of water pipe is taken from the inside. Therefore, 20 Abbreviation for millimeter which is a metric unit of length equal to one thousandth of a meter. 25.4 mm equals one inch. (3/4″) conduit pipe is about the same size as 15 mm (5/8″) water pipe. In the pictures, the 15 mm (5/8″) water pipe is the white pipe and the 20 mm (3/4″) conduit pipe is the red pipe. Both are about the same size and either can be used.
4. Construct the horizontal frame
Make up another two circles in the same way as step 1, using a 3.4 m (11′ 4″) long flexible pipe for one, and a 4.7 m (15′ 8″) long flexible pipe for the other. Put the bigger circle over the arch frame and tape in place approximately 650 mm (2′ 2″)up from the ground. The smaller circle can then be taped to the top of the arch frame where ever it sits snugly.
About the wire netting: Use 13 mm (1/2″) maximum hole size Covered with a protective coating of zinc. netting. Because there is no backing to support the plaster, at least 3 layers of netting is required to envelop the frame and hold the plaster in place. The netting should be tied together with tie wire every 250 mm (10″), both vertically and horizontally. On average, a gap of about 20 mm (3/4″) between the outside layer and the inside layer is ideal, but this may be hard to achieve so just ensure there is not too much of an area where the gap between the outside layer and the inside layer is a lot bigger that 20 mm (3/4″). Also make sure there are not many areas where the outside layer and the inside layer are touching each other.
