Ka whakarōpūtia ngā niho o mua me muri o ngā mekameka motopaika kia rite ki ngā whakatakotoranga, ki ngā rahi rānei, ā, ka wehea ngā tauira taputapu ki te paerewa me te kore paerewa.
Ko ngā tauira matua o ngā taputapu ine ko: M0.4 M0.5 M0.6 M0.7 M0.75 M0.8 M0.9 M1 M1.25. Me tāuta te porotiti ki runga i te rakau, kaua e piko, kaua hoki e hū. I roto i te huihuinga tuku kotahi, me noho ngā mata pito o ngā porotiti e rua ki te papa kotahi. Mēnā he iti iho i te 0.5 mita te tawhiti pokapū o ngā porotiti, ko te rerekētanga e whakaaetia ana ko te 1 mm; mēnā he nui ake i te 0.5 mita te tawhiti pokapū o ngā porotiti, ko te rerekētanga e whakaaetia ana ko te 2 mm.
Ngā mōhiohio whānui:
Kia tino pakaru te porotiti, me whakakapi he porotiti hou me te mekameka hou i te wā kotahi kia pai ai te hononga. Kāore e taea te whakakapi noa i tētahi mekameka hou, i tētahi porotiti hou rānei. Ki te kore, ka ngoikore te hononga, ā, ka tere ake te pakaru o te mekameka hou, o te porotiti hou rānei. Kia pakaru te mata o te niho o te porotiti ki tētahi taumata, me huri i te wā tika (e pā ana ki te porotiti e whakamahia ana me te mata whakarerekē). kia roa ake ai te wā whakamahi.
Kāore e taea te whakaranu i te mekameka hiki tawhito me ētahi mekameka hou, ki te kore ka pā kino ki te tuku, ka whati te mekameka. Kia mahara ki te tāpiri hinu whakahinuhinu ki te mekameka hiki i te wā e mahi ana. Me tomo te hinu whakahinuhinu ki te āputa i waenganui i te roera me te ringaringa o roto hei whakapai ake i ngā āhuatanga mahi me te whakaiti i te pakaru.
