Ka hangaia ngā puranga rino āhua-U mā roto i tētahi tukanga maha-taahiraa e whakakotahi ana i te tika me te mana kounga tino pakari. Anei tētahi whakamārama taipitopito:

Tuatahi, ka tīpakohia te maitai kaha-teitei hei rauemi turanga. Ka tukuna ngā tukanga maimoatanga-mua pērā i te tapahi, te miihini, me te maimoatanga wera kia tutuki ai ngā whakaritenga e hiahiatia ana i mua i te tīmatanga o te mahi hanga. Muri iho, ka whakawhanakehia ngā pokepoke ritenga—tae atu ki ngā wāhanga o runga, o raro, me te taha—i runga i ngā tawhā hoahoa o ngā puranga rau. Kātahi ka whāngaihia ngā pereti maitai kua tukatukahia ki roto i ngā mīhini piko matao, ka hangaia ki te āhua-U mā te hanga matao whakahaeretia.

I muri i te hanganga, ka tapahia, ka kerihia hoki ngā puranga rau, kia rite ki ngā whakaritenga hoahoa hei whakahaere i te honohono me te tāutanga i te papaanga. Mō ngā kaupapa e hiahia ana ki ngā pakitara roa ake, ka honoa ngā puranga rau takitahi hei hanga i ngā wāhanga roa. Hei whakarei ake i te pakari, ka whiwhi ngā hua kua oti i ngā maimoatanga mata pērā i te rehu, te whakakākahu rānei, e whakanui ana i te ātete ki te waikura me te waikura. Hei whakamutunga, ka tākaihia ngā puranga rau maitai āhua-U kua oti kia haumaru ai te kawe ki ngā papahanga hanga.

Mai i te whakarite rauemi mata ki te takai whakamutunga me te tuku, me piri pono ki ngā paerewa kounga me ngā paerewa tukanga i ia wāhanga o te tukanga whakaputa. Mā tēnei huarahi tino tupato ka tutuki i ngā puranga pepa kua oti ngā whakaritenga mahi me te pono mō ngā tono hangarau rangitahi me ngā tono pumau.
