Nā ʻano hana lāʻau
Hana ʻia ka hana lāʻau me nā mīkini hana lāʻau like ʻole. Hoʻohana ʻia nā mea hana kamana lima ma ke ʻano he mea kōkua no ka hui ʻana a me ka hoʻokuʻu ʻana i nā huahana i loko o nā ʻāpana, a me nā mea ʻē aʻe.1). Ma ke ʻano he mea hana no ka ʻokiʻoki, ʻokiʻoki a hoʻomaʻamaʻa ʻia, hoʻohana ʻia nā ʻili kuʻi, nā ʻili pōʻai a me nā kiko, nā pahi no ka ʻokiʻoki a me ka ʻoki ʻana, nā mea ʻoki wili, nā wili, nā kaulahao, nā ʻoki a me nā pepa.
Kiʻi1- Nā ʻano o ka hana lāʻau: a - ʻoki; b - ʻoki; c - wili; d - wili; e - ʻōpala; f — wili.
ʻO nā pahi a me ko lākou mau kihi
ʻO nā mea hana ʻokiʻoki, i hoʻohana ʻia no ka hoʻoponopono ʻana i ka lāʻau, loaʻa mau i hoʻokahi a i ʻole kekahi mau wili. No laila, no ka laʻana, ʻo nā niho o ke kiʻi, ka pōʻai a me ka ʻili hui, nā ʻili o nā pahi ʻōpala, nā niho o nā mea ʻoki wili, a me nā mea ʻē aʻe he ʻano o nā ʻokiʻoki e hana i ka ʻoki. I mea e hiki ai i kēia mau lau ʻano wedge ke ʻoki i ka lāʻau me kahi huahana kiʻekiʻe loa a hāʻawi i ka maikaʻi o ka hoʻoponopono ʻana, pono lākou ma kahi kihi i nā ʻāpana lāʻau a loaʻa kahi nui a me ke ʻano.
Ma luna o kēia mau mea ʻokiʻoki, i hoʻohana ʻia no ka hana ʻana i ka lāʻau, aia nā kihi ʻoki ʻoki: ʻo ka ʻoki ʻoki, i hōʻike ʻia e ka leka δ, ka ʻoki ʻoki - ma ka leka β, ka kihi mua - ma ka leka γ, ka kihi hope - e ka leka α. Hāʻawi mau ka huina o ka ʻaoʻao hope a me ka ʻoi ʻoi i ka huinaδ = α + β(fig.2).
Kiʻi2— Nā ʻāpana kihi o ka maka.
I mea e hoʻokō ai i ka maʻemaʻe kiʻekiʻe o ka hana ʻana i ka ʻili o ka lāʻau a e hoʻolilo i ka hana liʻiliʻi e like me ka hiki ke ʻoki, pono e koho i ka kihi ʻoki maikaʻi loa, ka ʻoki ʻoki ʻana, ke kihi ʻoki mua a me hope e like me ke ʻano o ka lāʻau, kona haʻahaʻa a me ke kuhikuhi ʻoki. E like me ka liʻiliʻi liʻiliʻi liʻiliʻi ʻoi, ʻo ke kihi o30°; lawe ʻia ka ʻaoʻao o ka neʻe ʻana o ka pahi a i ʻole ke kihi hope10-15°; lawe ʻia ka ʻoki ʻoki45-74°.
ʻO ke kuhikuhi ʻoki ʻana e like me nā fiber
E like me ke kuhikuhi o ka ʻoki ʻana e pili ana i nā ʻili lāʻau, ʻekolu mau hihia nui o ka ʻoki ʻana: frontal, longitudinal a me transverse (Fig.3). ʻO ka lōʻihi maʻemaʻe, transverse a me ka ʻoki mua ʻana i hana ʻole ʻia, no ka mea, ʻo ka pahi i ka wā o ka hana aia mau i kahi kihi i ka ʻai o ka lāʻau.
Kiʻi3- ʻEkolu mau hihia nui o ka ʻoki lāʻau: a - mua; b - lōʻihi; c — huli.
Hoʻokala i nā mea hana
Hana ʻia ka ʻokiʻoki ʻana i nā mea ʻoki kūikawā a i ʻole ma ka lima, me ka ʻoiaʻiʻo o ka mea ʻokiʻoki, ma hope o ka hoʻomaʻamaʻa ʻana, pono e mālama i ke ʻano kumu o ka maka a me nā ʻano angular pili.
Nā kumuhana pili: bandsaws, nā mīkini ʻili pōʻai, lāʻau ʻala o nā lāʻau coniferous a me nā lāʻau paʻakikī, hale a me ka hana ʻana i nā puka makani lāʻau a me nā puka.
