Ko te wāhanga tā hohonu whakarewa he tikanga hanga o tētahi mea mahi (wāhanga pēhi) o te āhua me te rahi e hiahiatia ana mā te whakamahi i te kaha o waho ki tētahi pereti, ki tētahi rīpene, ki tētahi paipa, ki tētahi kōtaha, me ērā atu mea mā te pēhi me te mate (pokepokea) hei whakaputa i te āhua kirihou, te wehenga rānei. Ko te tā me te hanga he rite tonu ki te tukatuka kirihou (te tukatuka pēhanga rānei), e kiia ana ko te hanga. Ko ngā pepa tā he nuinga ngā rau maitai me ngā rīpene kua hurihia wera me te hurihia matao.
Ko te nuinga o ngā tānga hohonu ka hangaia mā te tā i ngā pepa whakarewa, pepa kore-whakarewa rānei mā te pēhanga o te mīhini tā.
Ngā Āhuatanga Matua
Ko ngā wāhanga tānga hohonu whakarewa ka hangaia mā te tānga i raro i te kaupapa o te iti o ngā rauemi e pau ana. He mama ngā wāhanga, he pakari hoki, ā, i muri i te whakapohehe kirihou o te rauemi pepa, ka whakapaitia te hanganga o roto o te whakarewa kia pai ake ai ngā wāhanga tānga. Kua piki ake te kaha.
I roto i te tukanga tā, nā te mea kāore te mata o te rauemi i pakaru, he pai te kounga o te mata, he maeneene hoki te āhua, ā, he ataahua hoki, e whakarato ana i ngā āhuatanga watea mō te peita mata, te whakakikorua hiko, te whakapūtātanga, me ētahi atu maimoatanga mata.
Ki te whakatauritea ki ngā mahi whakarewa me ngā mahi hanga, he angiangi, he ōrite, he māmā, he kaha hoki ngā wāhanga tā. Ka taea e te tā te hanga i ngā mea mahi he rara, he riu, he piko, he whatu rānei, he uaua ki te hanga mā ētahi atu tikanga hei whakanui ake i tō rātou pakari. Nā te whakamahinga o ngā pokepokea tika, ka eke te tika o te mea mahi ki te maikorona, ā, he teitei te āheinga ki te tāruarua.
Tukanga Tā Tā Hōhonu
1. Me tino māmā, kia ōrite hoki te āhua o ngā wāhanga kua tuhia, ā, me tuhi kia tawhiti rawa atu.
2. Mō ngā wāhanga e hiahia ana kia hōhonuhia kia maha ngā wā, me waiho kia whai tohu ngā mata o roto, o waho hoki, ka puta pea i te wā e tuhi ana, me te whakarite hoki i te kounga o te mata e tika ana.
3. I raro i te kaupapa o te whakarite i ngā whakaritenga huihuinga, me whakaaetia te pakitara taha o te mema kume hohonu kia whai i tētahi piko.
4. Me tika te tawhiti mai i te taha o te kōhao, i te taha rānei o te flange ki te pakitara taha.
5. Me tika te raro me te pakitara o te wahi tuhi hōhonu, te flange, te pakitara, me te radius kokonga o ngā kokonga o te wāhanga tapawhā rite.
6. Ko ngā rauemi e whakamahia ana mō te tuhi, me whai āhua pai te kirihou, he iti te ōwehenga hua, he nui te tauwehenga aronga matotoru o te pereti, ā, he iti te aronga aronga papa pereti.
