Whakatakotoranga Hua

1. He momo tokotoko ngote motuhake te tokotoko whakakanapa e honoa ana ki te tokotoko ngote me te whakairi kurupae. Kei te tihi o te tokotoko ngote, me mau te kaha nui, kia nui ake te diameter me te kounga maitai teitei ake i te tokotoko ngote, ā, he maeneene te mata.

2. Mahi matua:

I honoa ki te kete tākai i roto i te pouaka tākai hei hiri i te pane o te puna me te aukati i te whakakitenga o te hinu, te hau, me te wai.

Hononga wā poto i waenga i te tokotoko ngote me te whakairi pane muera

Whakamātautau hoahoa tohu whakaoti.

Whakaotia ngā mahi a te pane puna, pērā i te patu papu, te whakahaere i te tautuhinga papu.

Kia mōhio: Ki te kore e taea te ine i te kaha tuku iti rawa, me whakaaro kia tukatukahia hei tauira paerewa, ā, me tāuta he inenga whānui hei ine.
He mea hanga i te maitai waro kounga teitei, ka taea te eke ki ngā āhuatanga miihini o te tēpu b Ko te maitai molybdenum (engari kāore i te herea ki tēnei momo maitai anake) te mea e whakamahia whānuitia ana, ā, mā te maimoatanga wera whai hua ka taea te whakatutuki i ngā āhuatanga ā-pūkaha o tēnei ripanga
