He maha ngā painga o te whiriwhiri i ngā takirere pūrerehua i runga i tētahi atu momo takirere whakahaere, pērā i ngā takirere pōro, ngā takirere pītiti, ngā takirere tinana koki, ngā takirere porowhita, ngā takirere piston nohoanga koki, me ngā takirere tinana koki.
1. He māmā, he tere hoki te whakatuwhera i ngā takirere pūrerehua.
Mā te hurihanga o te kakau e 90° ka kati katoa, ka whakatuwhera rānei i te takirere. Ko ngā takirere pūrerehua nui he mea e kiia nei he pouaka miihini, e honoa ana te wira ringaringa ki te kakau mā te whakamahi i ngā taputapu. Mā tēnei ka māmā ake te mahi a te takirere, engari ka iti ake te tere.
2. He iti te utu o te hanga i ngā takirere pūrerehua.
He iti ake te rauemi e hiahiatia ana mō ngā takirere pūrerehua nā te mea he hoahoa paipa. Ko te mea tino ohanga ko te momo wafer e uru ana ki waenganui i ngā flange paipa e rua. Ko tētahi atu momo, ko te hoahoa wafer lug, ka puritia ki waenganui i ngā flange paipa e rua mā ngā pūtu e hono ana i ngā flange e rua ka puta mā roto i ngā kōhao i te anga o waho o te takirere. Hei tāpiri, he iti ake te utu o ngā rauemi noa mō ngā Takirere Pūrerehua.
3. He iti ake te wāhi e hiahiatia ana mō ngā takirere pūrerehua.
Nā te hoahoa kiato tēnei, he iti ake te wāhi e hiahiatia ana, ki te whakaritea ki ētahi atu takirere.
4. Ko ngā takirere pūrerehua e hono ana ki te whakaiti i te tiaki.
