1. Whakaahuatanga momo tākai graphite
E toru ngā momo whakakī e whakamahia whānuitia ana i roto i ēnei e whai ake nei:ngā takirere
Ko te momo takai i whakamahia i tēnei kaupapa ko te momo whakatuwheratanga kotahi i te Pikitia 1 me te momo takai porowhita i te Pikitia 3. Ko ngā whakaahua tuturu e whai ake nei:
Pikitia 1 Momo tākai whakatuwheratanga kotahi
Pikitia 3 Te whakakī mowhiti whakakī
He rite tonu ngā mahi whakamahi o ngā takai e rua i runga ake nei, ko te rerekētanga kei roto i ngā āhuatanga whakamahinga rerekē. He pai te takai whakatuwheratanga kotahi mō te whakakapi i te takai i te wā e tiakina ana te takirere o ia rā. Ka taea te whakakapi i te takai i runga ipurangi, ā, he pai te takai mowhiti takai mō te whakahou i te takirere. Whakamahia mō te wetewete me te tiaki.
2. Whakaahuatanga o ngā āhuatanga tākai karāpeti
E ai ki ngā whakaritenga hangarau o te hanga whakakī, me whai reiti pakari te whakakī, kia mau ai te pakari mai i roto ki waho i muri i te hanganga o te whakakī. Ko ngā momo whakakī karāti kotahi-wāhanga kua whakahuatia ake nei ko ngā whakakī whiri, ā, ko te tukanga hanga he whiri maha ngā muka karāti, ā, ka mimitihia te pakari e te āputa whiri, ā, kāore he tohu mārama o te hiahia kia whānui. Ko te karāti momo mowhiti tākai he tākai kiato me te roto kiato. I muri i te tūnga roa, ka kitea he pakaru o te pakari o roto i te mata o te tākai, ā, ka tukuna tēnei wāhanga o te ahotea. Ka noho pumau tēnei momo whakakī, ā, kāore e rerekē i muri i te hanga o tētahi pakaru. Ina pēhia anō, ka ngaro te pakaru, ā, ka tutuki te reiti whakahoki i te whakaritenga.
Ko ngā whakaritenga hangarau e whai ake nei mō ngā mowhiti karāhe ngāwari

3. Mō te whakamahinga o te tākai karāhe
Ka whakamahia te takai karāpeti i roto i te wāhi hiri i waenganui i te kakau takirere me te repe takai, ā, kei roto te takai i te āhua kōpeke i te wā e whakahaerehia ana. Ahakoa he momo takai whakatuwheratanga kotahi, he momo takai mowhiti rānei, kāore he rerekētanga o te mahi o te āhua kōpeke.
Koinei te hoahoa o te āhua mahi o te takai (whakaahua o te whakamātautau hiri takai)
