Utauta tapahi tarutaru maitai konupora matotoru
He mata tapahi tarutaru ōhanga, pakari hoki, he mea hanga ki ngā rauemi matotoru me te hangarau whakamahana pūtaiao, ā, ka tino whakarei ake i te ātete ki te kakahu. He taurite hihiri tika, he iti te wiri, he pai te tiaki i te kakau matua o ngā mīhini ahuwhenua. Ahakoa he taru i te mara, he whakamakuku whakaranu rānei i roto i ngā māra hua, ka taea te whakatika ngāwari. Mā te hoahoa tuwhera paerewa ka ngāwari te tāuta, ā, he pai mō ngā momo waitohu taputapu tapahi tarutaru, ka āwhina i ngā kaiwhakamahi ki te whakaiti i ngā utu tiaki.
He mea tā te tohu o tēnei hua mai i te maitai konupora 65Mn kounga teitei, te maitai waro 50 # rānei (i runga i te tauira motuhake). Whai muri i te maimoatanga tinei me te whakamahana i te pāmahana teitei, ka eke te pakeke o te mata ki te HRC 45-50, ehara i te mea he koi rawa, engari he pakari rawa hoki. Mō ngā taiao kakahu nui, kua oti ētahi tauira te whakarewa koranu mārō, te maimoatanga whakakākahu rānei hei hanga i tētahi paparanga ātete kakahu i runga i te mata, hei ātete pai i te kakahu onepū me te kohatu, ā, ka roa ake te ora o te mahi.
Kua hangaia te mata o tā mātou mīhini tapahi tarutaru me te whai whakaaro nui ki te āhuarangi me te ātete tapahi. He hoahoa ngāwari te mata, ā, ka taea e te piko motuhake te whakaiti i te ātete i te wā tapahi, te whakaiti i te kawenga ki te tarakihana, ki te mīhini tapahi tarutaru rānei, me te whakatutuki i te mahi penapena wahie me te whai hua. Ahakoa he mata hurihuri, he mata hama, he mata tika rānei, kua whakamatautauria ia momo mata kia mau tonu ai te pumau i raro i te hurihanga tere-teitei, kia whakaitihia te wiri, kia tiakina ai te pou tuku me te pouaka miihini.
He kaha te urutau o tēnei mata tapahi tarutaru tāpiri, ā, he whānuitia te whakamahinga i roto i ngā tapahi tarutaru taha, ngā mīhini hurihuri, ngā mīhini whakahoki tarutaru, me ngā momo taputapu tapahi tarutaru o muri o te tarakihana. Ehara i te mea ka taea e ia te whakakore noa i ngā taru, ngā rakau iti, me ngā wiwi, engari ka taea hoki te tapahi me te kuru i ētahi waina iti ake te whānui me ngā tipu rakau, ka hoki mai te kakau witi ki te mara, ka whakapiki ake hoki i te matū koiora o te oneone.
Hei whakahaere i te whakakapinga a te kaiwhakamahi, ka hangaia ngā kōhao tāutanga o te mata kia rite ki ngā inenga paerewa (pēnei i te tawhiti o te kōhao waenga me te whānui o te kōhao pūtu), kia tino hototahi ai ki te kaipupuri mata taketake. E taunakihia ana kia tirohia te pakaru o te mata i ia 8-10 hāora o te mahi kāinga, ā, kia tere te whakakapi i ngā mata kua pakaru rawa. Ehara i te mea ka whakarite noa i te kounga tapahi, engari ka ārai hoki i ngā aituā haumaru miihini e puta mai ana i te pakaru o te mata.
