1. Te wāhi rangahau
Me tata te hanga o te onepu me te kirikiri, i runga anō i ngā here o ngā rauemi me ngā āhuatanga kawe. Haunga te whānuitanga haumaru o te pupuhi maina, me te utu kawe o ngā rauemi mata me ngā hua kua oti, ka hangaia te raina whakaputa i te taha tata. Ko ngā whāinga rangahau ko te wāhi whenua o te mara onepu me ngā rauemi e wātea ana, ā, he mahere whānui mō te wāhi o te raina whakaputa.

2, te tukanga whakaputa onepu hoahoa
E toru ngā wāhanga o te tukanga hanga onepu, arā, te kuru tuatahi, te kuru waenga, me te kuru pai.
Ka haria te konganuku karāhe ki te papa tango o te awheawhe kuru, ā, ko te karāhe he iti iho i te 800 mm te rahi o te matūriki ka haria e te whāngai wiri me te taputapu tirotiro; ka taka tika te karāhe iti iho i te 150 mm ki runga i te kawe whitiki ka tomo ki te papa rokiroki tuatahi; ko te rauemi nui atu i te 150 mm i muri i te kuru tuatahi o te kuru kauae, ka tukuna hoki te rauemi pakaru ki te papa tuatahi. I muri i te tirotiro-mua mā te mata wiri, ka tātari tika te rauemi iti iho i te 31.5 mm, ā, ko te rauemi he nui ake i te 31.5 mm te rahi ka tomo ki te kuru waenga o te kuru pānga. I muri i te kuru me te tirotiro, ka tomo pai ake te rauemi neke atu i te 31.5 mm ki te kuru. I muri i te kuru, ka tomo ki te mata wiri porowhita e toru-paparanga ka tirotirohia kia toru ngā rahi o ngā kohatu kirikiri karāhe, 0 ki te 5 mm, 5 ki te 13 mm me te 13 ki te 31.5 mm.
Ko ngā taputapu i whakamahia i te kuru tuatahi he kuru kauae, ā, ko ngā taputapu i whakamahia i te kuru ko te kuru pānga me te kuru pānga, ā, ko ngā kuru e toru me te awheawhe tirotiro e hanga tahi ana i tētahi tukanga whakaputa porowhita kati.

3, rokiroki hua kua oti
I muri i te haerenga ki te kuru me te tātari, ka haria ngā konganuku kirikiri karāhe e toru me ngā rahi matūriki rerekē ki roto i ngā pareparenga porowhita e toru, 2500 tana te taumaha, mā roto i ngā whitiki.
