Inanahi, kua oti i a mātou te uta i tētahi huinga mīhini kume waea tika;

Ko te mīhini tuhi waea tika, i hangaia mō te tuhi waea tika, kore-piko rānei kia pai ake ai te kukume, i hangaia e mātou kia rite ki ngā tono a ngā kiritaki;

Ko te diameter o te waea tomo he 5.5mm, ko te diameter o te waea putanga he 1.6mm mō te hanga mata whatu whakarewa;

E hiahia ana hoki ngā kiritaki ki te hanga whao, me waea 3mm, 4mm, 5mm te rahi, nō reira i whakaritehia e mātou te pokepokea tuhi kia rite ki tā rātou e hiahia ana;

Ngā taputapu āwhina hei pupuhi:

Tūnga utu waea, mīhini tango anga, mīhini tango waea, mīhini tohu pane, me te mīhini whakarewa papa;

He nui ake te whakaputanga o tēnei raina tuhi waea tika, ā, he pai te kounga o te waea kua oti mō te hanga mata whakarewa; ā, mai i te 5.5mm tika ki te 1.6mm, kāore e hiahiatia kia whakamahia te oumu whakamahana, engari he iti te utu o tēnei raina, nō reira he pai mō ngā kiritaki he nui ake ā rātou taputapu whakaputa, ā, he nui hoki te tahua;

Mena he iti tō tahua, ka taea e koe te whiriwhiri i te mīhini tuhi waea momo porotaka, he mea rongonui hoki, mai i te 5.5-1.6mm me tuhi tuatahi mai i te 5.5-2.0mm, kātahi ka kawe ki roto i te oumu whakamahana, ā, muri iho, whakamahia te mīhini tuhi waea tāke wai hei hanga mai i te 2.0mm ki te 1.6mm;

Mena kei a koe he mahere mō taua mea, tukuna mai he uiui me tō hiahia mō te diameter waea tāuru me te diameter waea putanga, ka whakaratohia e mātou he otinga whaitake ki a koe;
