Nga Taipitopito Hua
Rererererere
Ko te rewharewha rewharewha nga ahuatanga o te hanganga ngawari, te iti o te rahi, te taumaha marama, te iti o te kohi rauemi, te rahi o te whakaurunga, te tere tere, te hurihanga 90°, me te taipana taraiwa iti. Ka whakamahia ki te tapahi, ki te hono me te whakatika i te reo i roto i te paipa. Ko nga ahuatanga whakahaere wai me te kati me te mahi hiri.
Ka taea e te rewharewha kirihou te kawe paru, a ko te kohi wai i roto i te waha paipa he iti rawa. I raro i te pehanga iti, ka taea te hiri pai. He pai te mahi whakatikatika.
Ko te hoahoatanga o te pereti rerehua ka iti te mate parenga wai, ka taea te kii he hua whakaora hiko.
Ka taea e te rewharewha kirihou te kawe paru, a ko te kohi wai i roto i te waha paipa he iti rawa. I raro i te pehanga iti, ka taea te hiri pai. He pai te mahi whakatikatika.
Ko te hoahoatanga o te pereti rerehua ka iti te mate parenga wai, ka taea te kii he hua whakaora hiko.
Ko te kakau takirere he hanganga i roto i te rakau, i muri i te tinei me te whakamahana, he pai nga waahanga miihini matawhānui, te aukati i te waikura me te aukati. Ka whakatuwherahia, ka katihia te puera rerehua, ka huri noa te kakau takirere karekau e neke whakarunga, heke iho. Ehara i te mea ngawari ki te pakaru te tarapi o te kakau takirere he pono te hiri. He mea whakapumau ki te titi konutai pereti rerehua, ka hangaia te pito toronga hei aukati i te pakaru o te takirere kia kore ai e taka te kakau takirere ina pakaru ohorere te hononga i waenga i te kakau takirere me te pereti rerehua.
Mahinga hua
He maha nga waahi e whakamahia ana nga reera rewharewha. Ko nga mahi o nga hiko hiko hiko rererererere kua whakarapopotohia e whai ake nei:
1. Ko te tinana takirere o te rewharewha rerehua kirihou anake e hiahia ana ki te waahi whakaurunga iti rawa atu, a he maamaa, he pono hoki te kaupapa mahi;
2. He rite tonu nga ahuatanga o te rere o te ōrau, ka taea te whakamahi mo te whakahaere ture, te whakahaere i runga-atu ranei;
3. Ko te tinana o te puera rerehua kirihou e rite ana ki te flange paipa convex paerewa;
4. Ko te mahi ohaoha pai ake ka tino whanui te umanga tono o te rewharewha;
5. He nui te kaha rere o te rewharewha kirihou, a he iti rawa te mate o te pehanga i roto i te puera;
