Nā tete patupatuKo nga waahanga ka hangaia ma te hanga i nga mahi, na reira ka taea te wehewehe i te waahangawera weraawhakamau makariri, wera werakei runga ake i te whakarewatanga whakarewate whakamahana i te pāmahana, ko te whakanui ake i te pāmahana ka taea te whakapai ake i te kirihou o te whakarewa, te whakapai ake i te kounga o te mea mahi, kia kore e ngawari te pakaru, te teitei o te pāmahana ka whakaiti i te aukati whakarewatanga whakarewa, me te whakaheke i te tone ote patupatue hiahiatia ana nga miihini, heoi, he maha ngawera werate tukanga, He ngoikore te tika o te mea mahi, kaore i te maeneene te mata, he ngawari ki te oxidize nga waahanga hanga.

Te hanga maekeKo te pehanga kei raro i te pāmahana whakarewa whakarewa ote patupatu, whakamau makaririe pā ana te pēhanga ki te pāmahana noa o tete patupatu, me te teitei ake i te pāmahana noa, engari kare i runga ake i te whakamaarama whakamaaramatanga o te pehanga, i whakamahia kiwhakamahana whakamahanapehanga, nawhakamahana whakamahanahe teitei ake te tika, he maeneene te mata, he kore e kaha te aukati i te kaha deformation, ka puta te pāmahana o te makaririte patupatumongamonga o te hanga me te rahi pū he tiketike, no te mea he maheni te mata, He mahawhakamau makariria ka taea te whakamahi tika i nga waahanga maeke hei waahanga, hei taonga ranei kaore he tapahi. Heoi ano, ka pakaru nga whao nui i te wa e hangai ana me te pehi, no reira ka hiahiatia nga perehi tone nui mo te tukatuka.
Hei whakaoti i ngate patupatu a whakawera whakawerate mahi, te wera o te hanga tuatahi me tete hanga whakamutungate wera o te werate patupatu, ko te awhe pāmahana i waenga kia nui rawa atu, heoi, ki te mea he tiketike rawa te paanga o te whakamaarama tuatahi, he nui rawa te tipu o te witi konganuku e kore e puta te ahua o te werawera, ka heke iho te kounga o te maaka, te maarama ki te toki taraka taumaha. He whare hanga whare, he mahi mohio kua whakaritea ki tetahi taha o te whare.
Toka taraka taumahamahunga mahunganga waahanga o nga taputapu hangahanga, ka taea te whakamahi mo te tino tikate patupaturerekēte hanga rakaunga waahanga, he iti te utu miihini, he pai te kaha, whakamahia te werate patupatuhe nui, he matotoru hoki nga mea mahi, he mea nui te kaha, he iti te kirihou, ina he nui te kirihou o te whakarewa me te kore e nui te deformation, ko te huringa katoa ranei o te mahi whakahiato me te whakamahi, he pai ki te whakarereke kirihou o te whakarewa, te nuinga kaore whakamahiwera wera, Te hanga maekeka whakamahia kētia.
