Papa Whakakotahi Kounga Teitei
Ko te pukapuka tākai raka mowhiti (puka tākai whakapae) he wāhanga hono matua o te pūnaha tūāpapa raka mowhiti, e whakamahia ana mō te hononga whakapae o ngā wāhanga paerewa poutū hei whakarite i te pumau o te hanganga. Ka hangaia mā te whakarewa i ngā pane pukapuka tākai whakarewa e rua (he kōwhiringa te pokepokea ware pi, te pokepokea onepu rānei) me ngā paipa maitai OD48mm, ā, ka whakapirihia ki ngā pine poro raka hei hanga hononga pakari. Ka hipokina e te roa paerewa ngā whakatakotoranga maha mai i te 0.39 mita ki te 3.07 mita, ā, ka tautokona hoki ngā rahi ritenga me ngā whakaritenga āhua motuhake. Ahakoa kāore e pikau i te kawenga matua, he wāhanga tino nui o te pūnaha raka mowhiti, e whakarato ana i te otinga huihuinga ngāwari me te pono.

Ngā painga o te hanganga rino-raka
1. Whakaritenga ngāwari
He whānuitanga o ngā roa paerewa e tukuna ana e mātou (0.39m ki te 3.07m) ā, e tautoko ana hoki i te whakarite i ngā rahi motuhake kia rite ki ngā tuhi kia tutuki ai ngā whakaritenga hanga rerekē.
2. Te urutau teitei
He mea whaowhina ki ngā paipa rino OD48mm/OD42mm, ā, he pane tākai pokepokea ai he ware pi, he kirikiri rānei hei whakatutuki i ngā whakaritenga hononga o ngā pūnaha raka mowhiti rerekē.
3. Hononga pumau
Mā te whakamau ki ngā pine raka poro, ka whakarite kia mau te hononga ki ngā wāhanga paerewa, ā, ka whakamanahia hoki te pumau o te hanganga whānui o te tūāpapa.
4. Hoahoa māmā
Ko te taumaha o te pane o te pukapuka kaute he 0.34kg ki te 0.5kg anake, he mea watea mō te tāutanga me te kawe me te pupuri tonu i te kaha hanganga e tika ana.
5. Ngā tukanga kanorau
E rua ngā tukanga whakarewa, arā, te pokepokea ware pi me te pokepokea onepu, e whakaratohia ana hei whakatutuki i ngā āhuatanga tono rerekē me ngā whakaritenga utu.
6. Pūnaha Hiranga
Hei wāhanga hononga whakapae matua (pae whakawhiti) o te pūnaha raka mowhiti, ka whakarite i te pakari me te haumaru whānui o te anga, ā, kāore e taea te whakakapi.
