ʻAno niho & pitch
Pehea e koho ai i ke ʻano o ka niho a me ka pitch o ka lāʻau ʻike ? ʻO ka maʻamau, hoʻohana ʻia ka lau niho skip no ka ʻoki ʻoki ʻana, akā ʻo ka niho niho maʻamau a triangular paha no ka ʻoki kea.
Hāʻawi ʻia ka niho skip ma nā lau niho koʻikoʻi, nā niho me 3, 4 a me 6 mau ʻīniha; he ʻaʻa pāpaʻu ākea kona me ka nui o nā wahi no ka ʻōpala e ʻohi ai. E ʻoluʻolu, hiki ke hoʻopilikia maikaʻi ʻia ka maikaʻi o ka ʻoki ʻia e ka sawdust paʻi ma waena o nā niho.

Hoʻohana ʻia no ka ʻoki hohonu ʻana i nā ʻoki ʻoki. E waiho ana kēia maka i ka pau ʻana i ka ʻoki ʻoki ʻia ʻoiai ʻo ka lohi o ka hānai ʻana a me ka haʻalulu nui e hoʻomaikaʻi i ka pau ʻana o ka ʻoki.

Maikaʻi no ka hoʻohana maʻamau me ka pae o ka ʻoki ʻana i ka palaoa a me ka palaoa. Hiki ke hoʻokō ʻia kahi hopena kūpono me ka lohi o ka hānai ʻana a me ka haʻalulu maikaʻi.

ʻO ka maka maʻamau kūpono kūpono no ka ʻoki ʻana a hiki i 150mm a ʻokiʻoki i nā ʻāpana a hiki i 50mm mānoanoa, ʻoiai hiki ke ʻoki ʻia nā ʻāpana mānoanoa me ka hoʻohana ʻana i ka hānai lohi.
Hāʻawi ʻia ke ʻano niho maʻamau, a i ʻole triangular, ma nā lau me 10 a ʻoi aku paha nā niho i kēlā me kēia ʻīniha, ma muli o ka emi ʻana o ka lawe ʻana i nā mea, ʻaʻole pono ka waiho ʻana i nā ʻōpala.

Maikaʻi no ka ʻoki ʻana i ka plywood a me ka MDF a me nā metala non-ferrous a me nā plastic. Maikaʻi ka hoʻopau ʻana i ka wā e ʻoki ai i nā lāʻau maoli, akā pono e lohi ka nui o ka hānai ʻana a ʻaʻole ʻoi aku ka hohonu o ka ʻoki ʻana ma mua o 50mm. I ka wā e ʻoki ai i nā metala, e hoʻemi i ka wikiwiki e like me ka hiki ke ʻoki i nā metala ferrous a i ʻole ka hao.

ʻO kahi ʻoki ʻoki maʻemaʻe loa no ka lāʻau pāpaʻi, plastik a me MDF, ʻoiai maikaʻi loa no nā lāʻau maoli ke ʻole nā ʻāpana lahilahi loa (ma lalo o 25mm mānoanoa). He maikaʻi loa ka 14tpi a ma luna o ka hoʻohana ʻana i ka wikiwiki lohi i ka wā e ʻoki ai i nā metala non-ferrous. Pono e hoʻohana ʻia ka māmā hānai lohi i nā manawa a pau me ka hoʻopaʻa ʻana o ka niho lau.
Loaʻa pū nā lau me nā niho pitch variable (4-6tpi, 6-10tpi a me 10-14tpi) no nā noi ākea.
