1. Ka whakaritea ki te hononga pokanoa whanui me te hononga matua, he maha nga painga motuhake o te hononga ringaringa:
(1) Ma te whakamahi i te ringaringa roha ka ngawari te hanga me te whakaurunga o nga waahanga miihini matua. Ko te mahi miihini o te rakau me te kohao mo te whakauru i te ringaringa roha kaore e hiahiatia kia rite ki te pai o te whakaraeraetanga. Kaore he take mo te whakamahana, te whakamahana, te pehi ranei i nga taputapu i te wa e whakauruhia ana te ringaringa roha, me whakakaha noa nga tutaki kia rite ki te taipana e hiahiatia ana. A he watea te whakatikatika, ka taea te whakatika i te wira wira ki te waahi e hiahiatia ana i runga i te rakau. Ka taea hoki te whakamahi karekau roha ki te hono atu ki nga waahanga he ngoikore te weldability.
(2) Te roa o te ratonga me te kaha nui o te ringaringa roha. Ko te ringaringa roha e whakawhirinaki ana ki te tuku waku, karekau he ara matua hei whakangoikore i te waahanga hono, karekau he nekehanga whanaunga, karekau he kakahu i roto i te mahi.
(3) A, no te nui o te ringaringa roha, ka ngaro te mahi hononga, ka taea te tiaki i nga taputapu mai i te kino.
(4) Ka taea e te hononga o te ringaringa whanui te tu ki nga kawenga maha, a ka taea te hanga ki nga momo momo momo. E ai ki te rahi o te kawenga whakaurunga, ka taea hoki te whakamahi i nga ringaringa roha maha i roto i nga raupapa.
(5) He ngawari te wetewete i te ringaringa roha, he pai te whakawhiti. I te mea ka taea e te ringaringa roha te whakakotahi i te waahi o te rakau me te nui o te aputa rite, ka taea te wetewete i te raka ina wetewete, kia ngawari te wetewete i te waahanga hono. Ina piri te mata whakapiri, ehara i te mea ngawari ki te whakaputa waikura, he ngawari hoki te hono me te wetewete.
2. Torque taipana me te axial taipana o te ringa roha
(1) Ko te Torque Mt e pa ana ki te taipana ariā teitei i te wa e whakawhiti ana i te taipana parakore, me te kaha axial Ft e tohu ana ki te kaha axial teitei ka taea te whakawhiti me te kore e whakawhiti i te taipana. Mena ka tukuna e koe ehara i te taipana engari ano hoki te kaha axial.
(2) Te whakamau i te taipana MA o te raka
Ko te taipana Mt me te kaha axial Ft kua tohua i roto i te paerewa ka tatauhia i runga i te taumahatanga wiri e rite ana, a ko te taipana whakakoi o te tiwiri kia eke ki te whakatauranga e hiahiatia ana i roto i te ripanga tawhā hangarau.
