Kāwai
Te whakauru i a maatau hua hou, 12mm En818-8 te kaha teitei o te mekameka hiki whakarewa. I hangaia tenei mekameka hiki ki te whakatutuki i nga whakaritenga whakaarahanga tino kaha me te aro ki te haumaru me te mauroa.
Ko te rahi o te mekameka 12mm ka taea e ia te hapai i nga kawenga taumaha me te pupuri i te kaha me te pumau. He mea tino pai mo te hiki miihini taumaha, taonga hanga, etahi atu mea taumaha ranei i roto i nga whare putunga, wheketere me nga waahi hanga.
He aha te mea motuhake o tenei mekameka ko tana whai ki te paerewa En818-8. Ko tenei paerewa o te ao ka whakarite kia tutuki nga mekameka ki nga paerewa kounga teitei me te haumaru. He mea hanga motuhake mo te hiki i nga tono me te whakamatau i nga whakamatautau ki te whakarite i tona pono i roto i nga taiao tino wero.
Ko te kaha nui o te mekameka tetahi o ona ahuatanga matua. He mea hanga mai i te koranu motuhake e whakanui ana i tona kaha katoa me te mauroa, me te whakarite ka taea e ia te tu atu i nga kawenga tino taumaha me te kore e whakararu i te haumaru. Ma tenei ka tino pai mo nga mahi hiki taumaha.
Taupānga
Ko te haumaru te mea tuatahi mo nga taputapu hiki i nga wa katoa, a kaore tenei mekameka e pouri. I hoahoatia me nga ahuatanga haumaru penei i nga here haumaru kia mau tonu te utaina i roto i te huarahi hiki. Ko te kaha nui o te mekameka me te ū ki nga paerewa haumaru he pai te whiriwhiri mo tetahi mahi hiki.
I tua atu i tona kaha me nga ahuatanga haumaru, ko tenei mekameka hiki whakarewa he pai rawa atu te aukati i te waikura me te aukati kakahu. Ko te tikanga ko te mekameka ka mau tonu tana mahi ahakoa i roto i nga taiao kino, ka waiho hei haumi mo te wa roa.
Ko te whakakotahi i te rahi 12mm, te hanganga ture En818-8, te kaha teitei, te hanga koranu me te mauroa whakamīharo, ko tenei mekameka hiki te tino whiriwhiri mo o hiahia hiki katoa. Whakawhirinaki ki tona kounga ka waiho kia pai ake, kia haumaru ake hoki o mahi hiki.
