He Tirohanga Whānui mō ngā Pae Rino o te Anchor Hollow
Ka hangaia ngā pae rino pūnga kōhao i roto i ngā wāhanga, ā, ko te roa paerewa he 2.0, 3.0, 4.0 m rānei. Ko te whānui o waho paerewa o ngā pae rino kōhao kei waenga i te 30.0 mm ki te 127.0 mm. Mena e tika ana, ka honoa ngā pae rino kōhao ki ngā nati hononga. Ka whakamahia ngā momo mata wiri patunga tapu rerekē i runga i te momo oneone, i te papatipu toka rānei. He pai ake te pae rino kōhao i te pae totoka he rite te horahanga whakawhiti-wāhanga nā te mea he pai ake te whanonga hanganga e pā ana ki te piko, te porowhita me te piko pakari. Ko te mutunga mai he nui ake te piko me te pumau piko mō te nui o te rino.

Ngā Whakamahinga o ngā Rakau Punga Keri-ā-Whaiaro
I ngā tau tata nei, me te pikinga ake o te tono mō te tautoko hangarau whenua, kua whakahoutia tonutia, kua whakawhanakehia hoki ngā taputapu keri. I taua wā anō, kua piki ake ngā utu mahi me te reti, ā, kua piki haere te roa o ngā whakaritenga mō te wā hanga. Hei tāpiri, he pai rawa ngā pānga punga o te whakamahinga o ngā tokotoko punga poka keri-ā-ringa i roto i ngā āhuatanga whenua e ngāwari ana te hinga. Nā ēnei take i ara ake ai te whānui haere o te whakamahinga o ngā tokotoko punga poka keri-ā-ringa. Ko te nuinga o ngā tokotoko punga poka keri-ā-ringa e whakamahia ana i roto i ngā āhuatanga e whai ake nei:
1. Whakamahia hei tokotoko punga kua whakamātauhia: whakamahia i roto i ngā āhuatanga pēnei i te pari, te keri i raro i te whenua, me te ārai-mānu hei whakakapi i ngā taura punga. Ka keria e te tangata ake ngā tokotoko punga tuwhera ki te hohonu e hiahiatia ana, kātahi ka mahia te whakakī i te pito. I muri i te whakapakeketanga, ka whakamahia te kume;
2. Whakamahia hei puranga moroiti: Ka taea te keri i ngā tokotoko punga tuwhera ka taea te keri ki raro hei hanga puranga moroiti, e whakamahia whānuitia ana i roto i ngā turanga pourewa tipu hiko hau, ngā turanga pourewa tuku, ngā turanga whare, ngā turanga puranga pakitara pupuri, ngā turanga puranga piriti, me ētahi atu;
3. Whakamahia mō ngā whao oneone: e whakamahia whānuitia ana mō te tautoko pari, hei whakakapi i ngā tokotoko punga maitai tikanga, ā, ka taea hoki te whakamahi mō te tautoko i te poka turanga hohonu i te pari pari;
4. Whakamahia mō ngā whao toka: I roto i ētahi pari toka, i ētahi kauhanga rānei he nui te huarere o te mata, he whānui rānei te hononga, ka taea te whakamahi i ngā tokotoko punga poka e keri ana i a ia anō mō te keri me te whakakī i ngā poraka toka hei hono i ngā poraka toka kia pai ake ai te pumau. Hei tauira, ka taea te whakakaha i ngā pari toka o ngā huarahi tere me ngā rēriwe e ngāwari ana te hinga, ā, ka taea hoki te whakakapi i ngā whare paipa tuku iho hei whakakaha i ngā whakatuwheratanga kauhanga korekore;
5. Te whakapakari taketake, te whakahaere āwhati rānei. I te roanga o te wā tautoko o te pūnaha tautoko whenua taketake, ka pā pea ēnei hanganga tautoko ki ētahi raruraru e hiahia ana kia whakapakaritia, kia rongoatia rānei, pērā i te whakarerekētanga o te pari taketake, te taunga o te turanga taketake, me te hiki ake o te mata o te rori. Ka taea te whakamahi i ngā tokotoko punga poka e keri ana i a ia anō hei keri i te pari taketake, te turanga, te whenua rori rānei, me ētahi atu, hei whakakī me te whakau i ngā kapiti, hei ārai i te puta mai o ngā āwhati whenua.
