Ka whakamahia te whai wāhitanga o te mīhini whakatā hei whakamutu i te hanga me te tiaki i te tāutanga o te mata. Ka tangohia tētahi mata wiri raina, ā, ka tāutahia kia rua ngā mata wiri mata cantilever whakarara ki te tūranga taketake. E whā ngā mata wiri raina i tangohia tetahi i muri i tetahi, e waru ngā mata wiri mata cantilever i tāutahia, ā, e whā i tāutahia ki ia rūma tirotiro e toru me ngā rūma tirotiro e whā.

Te hanga anō i te kawe whitiki He roa te tinana o te mata wiri raina taketake, ā, me urutau me te whakaroa i te kawe whitiki e whāngai ana i te rauemi mata. Ka whakamahia te pūmau wira upoko cantilever kore-paerewa hei huri i te puku o te whakaiti motuka taketake ki tētahi momo pahu hiko hou e mau ana ki te motuka. Ka whakaitihia te wāhi taraiwa, ka karohia te hanga anō i te turanga sima, ā, ka penapenahia te utu me te wā hangarau.

Te hanga anō i te pūwero whāngai o te mata wiri Nā te mea e mahi tahi ana ngā mata wiri e rua, kua hangaia te pūwero whāngai hei momo silo e ai ki te mahi hangarau o te konganuku kua whakakāhia kia taea ai te waku i waenga i ngā rauemi, te whakaiti i te horo o te pūwero, me te whakakore i te pūwero tuku iho. Kāore he turuturu o te hāora i puta i muri i te whakamahinga o te pūwero.
