I kēia manawa, ma muli o ka liʻiliʻi o ka lāʻau maoli, ʻoi aku ka maʻalahi o ka ʻoihana lako e loaʻa i nā ʻano mea like ʻole e pani ai i ka hemahema o ka lāʻau. ʻO nā lako metala (kahi i ʻike ʻia ʻo nā lako lāʻau kila) kekahi o ke ala o ka hoʻomohala ʻana. I kēia manawa, nui nā ʻano lako metala ma ka mākeke ·Nā papaʻaina maʻamau, nā noho, nā moena, a me nā kaula. Ua kaulana nā lako ʻahaʻaina hōkele i nā mea kūʻai aku ma muli o kona puʻupuʻu ikaika, paʻa, kūpono ka halihali, a me nā mea ʻē aʻe, akā nui nā mea kūʻai aku e kūʻai mai.
No laila e like me nā kūlana kūpono, e hoʻomanaʻo iā ʻoe e hoʻolohe i nā ʻano aʻe i ke kūʻai ʻana:
(1) E nānā pono i ke ʻano o nā lako. ʻO nā lako metala ma ka mākeke ʻelua mau ʻano: nā lako electroplating, ʻo nā koi no ia mea ʻaʻole hiki i ka papa electroplating ke huʻa, ʻili, ʻaʻohe melemele, ʻaʻohe ʻōpala ma ka ʻili; nā lako pena, e hōʻoia i ka hāʻule ʻole ʻana o ke kiʻi pena, ʻaʻohe Wrinkle, ʻaʻohe kahe e maopopo, ʻaʻohe pimple, ʻaʻohe puʻupuʻu a me nā ʻōpala.
(2) ʻAʻole ʻae ʻia ka pā o ka paipu kila e loaʻa nā māwae a me ka welding wehe. ʻAʻole ʻike ʻia nā wrinkles i ka piko ʻana ma ka ʻāwili.
(3) ʻAʻole ʻae ʻia nā ʻāpana welding ma waena o nā paipu e loaʻa nā leaks, welding, a me nā wili uila, a ʻaʻole hiki i nā hemahema e like me nā pores, ke komo ʻana a me nā burrs.
(4) Pono ka riveting o nā mea metala a me nā paipu kila a ʻaʻole hiki ke wehe. Pono nā pāpale riveting e maʻalahi a palahalaha, ʻaʻohe burrs, ʻaʻohe ʻeha.
(5) Ke wehe ʻia a hoʻohana ʻia nā lako, maʻalahi a paʻa nā lako. Pono nā huahana hoʻopili e hōʻoia i ka hiki ke hoʻololi ʻia, akā ʻaʻole pono ke ʻano pelu.
Eia kekahi, i ka hoʻoneʻe ʻana i nā lako metala, e pale i nā puʻupuʻu a me ka ʻoki ʻana i nā papa pale pale; mai hoʻokomo i nā mea metala ma kahi kihi haʻahaʻa, pono e waiho ʻia i ka ʻumi maloʻo a me ka ea e pale ai i ka pala.
Nā lako ʻahaʻaina hōkele, ka noho ʻahaʻaina hōkele, ka noho ʻahaʻaina, nā lako hale hōkele, nā lako ʻahaʻaina
