Ko te whanau poi porohita o waho he momo rerekee o te poi whao hohonu, e tohuhia ana ko te mata diameter o waho o tona mowhiti o waho he porowhita, ka taea te whakauru ki roto i te mata porowhita o te nohoanga o te noho hei purei whaiaro- whakahāngai tūranga.

Ahakoa kia rite ana mahi taketake ki tera o te riipene porowhita hohonu, engari na te mea ka whakamahia te nuinga o enei tohu ki roto i nga miihini ahua taratara, kaore i te tino tika te whakaurunga me te tuunga, ko te tuaka o te rakau me te kohao o te nohoanga he kore e tika ana, he roa te take, he paopao.I roto i te take o nga tohu nui, me te tika o te whanau ake kaore i te teitei, me etahi hanganga he ahua taratara, ko te tino mahi o te mahi noa he iti noa te utu mo nga tohu porowhita hohonu o te tohu kotahi.Hei tauira, ka whakamahia te porowhita porowhita o waho me te waea o runga mo te kaa ma te maaka me te paheketanga.Ko tenei momo kawe he mowhiti hiri ki nga taha e rua hei aukati i te whakaekenga o te paru.Ka whakakiia ki te nui o te hinu whakahinuhinu i te wheketere me te kore e tika kia horoia i mua i te whakaurunga.Karekau he whakahinuhinu taapiri e hiahiatia ana, i te wa ka whakakikitia te wiri o runga ki te pito e puta mai ana o te mowhiti o roto e mau ana i runga i te rakau.Ko te kawenga axial e whakaaetia ana kaua e neke ake i te 20% o te kawenga hihiri kua whakatauhia.

He rite tonu te mahi o te kawe poroi porohita o waho me te ringaringa rereke ki tera o te kawe porowhita o waho me te waea o runga, engari ko te waea o runga kaore i te whakakai o roto engari kei runga i te ringaringa kee.Ko te kohao o roto o te poroporo porowhita o waho e mau ana me te kohao tapatapahi he kohao tapatapahi me te 1:12 taper, ka taea te whakanoho tika ki runga i te kaakaa whariki, ka whakairihia ranei ki runga i te rakau whatu kaore he pakihiwi ma te ngahere i mau tonu. a ka taea te whakatika i te waahi o te kawe.
