New – I organised my ferro videos on Youtube in a playlist called Ferrocement Tips:
We have an order for public sculptures of 6 gourds brought by the first Maori to Gisborne.. Two are done and placed in the Captain cook memorial park, and now we are doing the last 4. The shape is suitable for water containers too…
The way I built the frames for these two was pretty quick- I drew the profile on recycled particle board, screwed screws along the profile for bending the vertical ribs to, measured the length, cut nine d10 (10mm deformed ie indented) rebars for the large gourd, 6 for the 900mm one, then bent them to the line of screws. I pre-bent the right angle bends at the base using a bender tool.
Then D10 horizontal ribs, circles (bent around a barrel and a concrete cone cast from a road cone) were tied to the vertical ribs on the inside. Then I wound fencing wire (medium tensile, heavier gauge ‘no.8’ wire) around the outside of the ribs. The ribs of the big gourd were supported by a drum shape bent from 150mm square mesh.
