He taputapu nui ngā papa kōhatu i roto i te ao hangarau tika, inā koa i roto i te whakamātautau me te whakatikatika i ngā wāhanga whatu. He mea hanga mai i te kōhatu tūturu, ka whakaratohia e ēnei papa he mata pumau, he papatahi hoki, he mea nui mō te whakatutuki i ngā inenga tika i roto i ngā tono whakamātautau whatu.
Ko tētahi o ngā painga matua o ngā papa granite ko tōna papatahi tino pai. Ka āta hangaia ngā mata o ēnei papa kia tino papatahi, i roto i te torutoru maikoroni te rahi. He mea nui tēnei taumata tika ina whakamātautauhia ngā wāhanga whatu pēnei i ngā karāhe me ngā whakaata, nā te mea ahakoa he iti noa te pekanga ka hua ake he hapa nui i roto i te mahi. Mā te whakarato i tētahi papa tohutoro pono, ka whakarite ngā papa granite ka taea te whakarite me te ine tika i ngā wāhanga whatu.
E mōhiotia ana hoki te karāhe mō tōna pakari me tōna ātete ki te kakahu. Kāore i rite ki ētahi atu rauemi ka taea te whakapē, te kakahu rānei i roto i te wā, ka mau tonu te āhua o te karāhe, kia mau tonu ai te mata whakamātautau mō ngā wā roa. He mea nui tēnei pumau i roto i ngā whakamātautau whatu, me puta he hua pono i ngā inenga maha. Nā ngā āhuatanga ā-roto o te karāhe ka iti ake te ngawari ki te horapa wera, ka pā ki te tika o te ine. He mea nui tēnei āhuatanga i roto i ngā taiao e kitea whānuitia ana ngā rerekētanga pāmahana.
Hei tāpiritanga, he maha ngā wā ka whakamahia ngā papa kōhatu me ngā taputapu whakamātautau whatu, pērā i ngā ine whakawhiti me ngā autocollimator. Me whai papa pumau ēnei taputapu kia pai ai te mahi, ā, ka whakaratohia e ngā papa kōhatu te tautoko e tika ana. Mā te whakakotahitanga o te mata papatahi me te pakari o te kōhatu ka taea te whakarite me te whakanoho tika i ngā wāhanga whatu, ka taea ai te whakamātautau me te aromatawai tika.
Hei whakamutunga, he mea nui te mahi a ngā papa kōhatu i roto i te whakamātautau i ngā wāhanga whatu. Nā te papatahi, te pakari, me te pumau o ēnei papa, he mea nui ēnei hei whakarite i te tika me te pono o ngā inenga whatu, ā, ka whai wāhi atu ki te whanaketanga o te hangarau whatu.
