Ko te nuinga o te mea he taputapu whakawhānui, he taputapu kati, he taputapu whakatuwhera me te kati taputapu me te whatanga, he taputapu piko, he papa mahi me te pūnaha whakahaere hiko;

2. Te kaupapa mahi:

(1) Whakatakotoria te wahi kotahi o te ngongo konumohe piko ki roto i te pokepokea piko o te mīhini piko;

(2) Pēhia te pātene tīmatanga, ka whakawhanuitia e te rango whānui te wāhanga kotahi, ka kati te rango kati i te ngongo konumohe, ka tukuna te rango whakatuwhera me te kati o te whatanga me te pinion ki te taputapu;

(3) Ka takahurihia e te rango hinu piko ngā pewa R i ngā pito e rua o te wahi kotahi ki te taha whakamuri mā te 30° mā roto i te whatanga me te pinion. Ina oti te piko, ka wetekina te rango hinu whānui ka whakahokia, ā, ka tangohia te ngongo konumohe piko;

(4) Pēhia anō te pātene tīmata, ka tautuhia anō te mahi katoa, ā, ka oti te mahi piko.

3. Ngā whakaritenga hanganga taputapu (he rerekē i ērā atu kaihanga):

(1) Whakanuia te taputapu tata o te pane piko me te taputapu whakatuwhera me te kati o te whatanga taputapu kia tika ake ai te hanganga o te tukanga.

(2) Whakanuia te taputapu whakanoho porowhita o te pane piko kia rite ai te koki piko.
