I mua, i whakamahia e ngā peera wira o ngā motuka he peera roera kotahi te rarangi, he peera pōro rānei, he takirua. Nā te whanaketanga o te hangarau, kua whānuitia te whakamahinga o te waeine pokapū motuka i roto i ngā motuka. Kei te piki haere te whānuitanga o te whakamahinga me te nui o te waeine pokapū i ia rā, i ia rā, ā, kua whanake ki te whakatupuranga tuatoru: ko te whakatupuranga tuatahi he peera whakapā koki rarangi rua. Ko te whakatupuranga tuarua he flange kei te ara rere o waho hei whakapiri i te peera, ka taea te whakakī noa i te peera ki te toki ka whakapiri ki ngā nati. Ka māmā ake te tiaki i te motuka. Ka whakamahia e te waeine pokapū wira o te whakatupuranga tuatoru te whakakotahitanga o te waeine pokapū me te pūnaha parai ārai-raka ABS. Kua hangaia te waeine pokapū me te flange o roto me te flange o waho. Ka whakapirihia te flange o roto ki te pou taraiwa me ngā pūtu, ā, ka tāutahia e te flange o waho te peera katoa. Mēnā kua pakaru, kua tawhito rānei te peera wira, te waeine pokapū wira rānei, ka pakaru tō waka i runga i te huarahi, ā, ka kino pea tō haumaru.
