Me pēhea te whakaoti i ngā taputapu me ngā raruraru hangarau e pā ana ki te whatu i te pepa whatu i runga i te mīhini whatu porowhita kotahi a Jersey?

1. He matotoru te miro e whakamahia ana mō ngā whatu pōtae. E taunakihia ana kia whakamahia he arataki miro 18-ine/25.4 mm. Kia tata rawa te whāngai miro o te arataki miro ki te ngira.

2. Me whakarerekē ngā taputapu i roto i te pouaka whāngai miro o te pane mīhini i mua i te whatu, kia rite ai te ōwehenga whāngai o te miro whenua me te miro mānu. Ko te ōwehenga tuku whānui e whai ake nei: ko te whāngai miro whenua he 43 niho me te 50 niho; ko te whāngai miro mānu he 26 niho me te 65 niho.

3. I te tīmatanga o te whatu, me hoatu he kaha kukume ki te papanga hina hei whakamahi i ngā koropiko hou hei wetewete.

4. Ina neke hohonu rawa te totohu, me tata te ihu o te totohu ki te pito teitei rawa o te ngira whatu kia taea ai e te ihu o te totohu te whakahaere i ngā koropiko tawhito kia taea ai te wetewete mārire.

5. Kaua te roa o te miro e hanga ana i te miro mānu e roa rawa, ki te kore ka māmā noa te hanga tuitui. Ko te tikanga, me iti iho i te 7cm, me rite rānei.

6. Me taurite te kume me te takai, kia iti te kume, kia ngāwari te hanga i ngā rārangi whakapae ki te papanga hina; kia nui te kume, kia ngāwari te hanga kōhao ki te papanga hina.

7. Ko te tere whatu o te mīhini he 18-20 rpm mō ngā rauemi mata, ā, 22-24 rpm mō ngā rauemi mata kounga teitei ake.

8. Mēnā ka puta he hapa rārangi whakapae, ka iti ake te kukū whatu o te miro whenua, ka whakahaeretia i te 1.96~2.95 cN (2~3g).
