Ko te tukatuka totoro he tikanga tukatuka tā e whakamahi ana i te pokepokea ai hei hanga i tētahi wāhanga papatahi hei wāhanga tuwhera kau. Hei tētahi o ngā tukanga tā matua, he whānui te whakamahinga o te totoro. Ka taea te whakamahi i te tukanga totoro hei hanga i ngā wāhanga pakitara porotaka, tapawhā rite, takahanga, porowhita, kōniko, parapore me ētahi atu āhua koretake. Mena ka honoa ki ētahi atu tukanga hanga tā, ka taea hoki te whakaputa i ngā wāhanga he āhua uaua ake.

Whakamahia ngā taputapu tā mo te tukatuka totoro o ngā hua, tae atu ki: te tukatuka totoro, te tukatuka totoro anō, te tukatuka totoro whakamuri me te tukatuka totoro angiangi, me ētahi atu. Tukatuka totoro: Whakamahia te taputapu pereti pēhi hei whakamahi i te kaha wero o te wero hei kukume i tētahi wāhanga, i te katoa rānei o te rauemi papatahi ki roto i te kōhao o te pokepokea kōpiko hei hanga hei ipu me te raro. Ko te tukatuka o te pakitara taha o te ipu e whakarara ana ki te ahunga totoro he tukatuka totoro parakore, ko te tukatuka totoro o ngā ipu āhua kōniko (pīramiti rānei), ngā ipu āhua porowhita, me ngā ipu mata parapore kei roto hoki te tukatuka whakawhanui.

Te tukatuka totoro anō: arā, mō ngā hua kua hōhonuhia, kāore e taea te whakaoti i te tukanga totoro kotahi, me totoro te hua kua hangaia i muri i te tukatuka totoro hei whakanui ake i te hōhonutanga o te ipu kua hangaia.

Tukatuka totoro whakamuri: I te tukanga o mua, ka totoro whakamuri te mea mahi kua totorohia, ka huri te taha o roto o te mea mahi hei taha o waho, ā, ka angiangi ake te diameter o waho i te tukanga o te whakaiti. I roto i te kōhao o te pokepokea ai he diameter o waho he iti ake te diameter, ka whakaitihia te diameter o waho o te ipu me te raro, ā, ka angiangi te matotoru o te pakitara, e kore e whakakore noa i te rerekētanga o te matotoru o te pakitara, engari ka maeneene hoki te mata o te ipu.

E whai ake nei ka whakaurua mai ngā momo tā me te totoro whakarewa e rua ina whakamahia ana ngā taputapu tā:

1. Te tukatuka tuhi porotaka + (Tuhi porowhita): te totoro o ngā hua porotaka. He āhua papatahi te flange me te raro, he ōrite te pakitara taha o te rango, ā, he ōrite te horapa o te whakarerekētanga i te porowhita kotahi, ā, kua pakaru te huruhuru o te flange ka puta he whakarerekētanga tuhi hōhonu.

2. Te tukatuka tuhi porowhita+ (tuhi porowhita): Ko te whakarerekētanga o te huruhuru i runga i te flange he whakarerekētanga kume, engari ko te nui o te whakarerekētanga me te ōwehenga whakarerekētanga ka huri i te āhua o te kōtaha. Ko te nui ake o te piko, ko te nui ake o te whakarerekētanga kirihou o te huruhuru, ā, ko te iti ake o te piko, ko te iti ake o te whakarerekētanga kirihou o te huruhuru.
