ʻOki ʻoki anu: ʻo ia ka wā e hoʻohuli ʻia ai ka metala i ka wikiwiki kiʻekiʻe, e ʻoki koke ʻia ka pahi ʻili pōʻai, a maʻemaʻe a maʻalahi ka ʻili.

ʻImi ʻoki wela: ʻike nui ʻia ʻo ka ʻoki ʻoki, i kapa ʻia hoʻi ʻo friction saw. ʻOki wikiwiki kiʻekiʻe me ka wela kiʻekiʻe, ʻokiʻoki i ka hopena o ka poni, multi burr.

ʻAno ʻili:

ʻOki ʻoki anuanu: ʻolo mālie ka ʻili maka wikiwiki, wili i ka paipu welded, no laila ʻaʻole hiki ke hoʻokō ʻia ka burr a me ka walaʻau. He liʻiliʻi loa ka wela o ka ʻeli ʻana, he liʻiliʻi ke kaomi ʻana o ka ʻili i ka paipu kila, ʻaʻole ia e hoʻololi i ka paia o ka paipu.

ʻili wela: ʻo ka ʻike lele lolouila maʻamau e hoʻololi i ka māmā kiʻekiʻe no ka pahi ʻike kila tungsten, a ʻo ka paipu pili e hoʻohua i ka wela e wāwahi ai. ʻIke ʻia nā kaha wela kiʻekiʻe ma ka ʻili. Hoʻokumu ʻia ka nui o ka wela, a ʻoi aku ka ikaika o ka pahi ʻike i ka paipu kila, ka hopena o ka deformation o ka paia paipu a me nā hemahema maikaʻi.
