MAKEMAKE: 1. ʻO nā hōʻailona i hōʻike ʻia no nā papa āpau o nā nati A194 no nā nati i hana ʻia i ke anu a me nā nati wela. Ke hana ʻia nā hua ʻai mai ka pahu pahu, pono e hoʻopaʻa ʻia ka nati me ka huapalapala 'B'. Hōʻike nā huapalapala H a me M i nā nati i mālama ʻia me ka wela. 2. ʻO nā waiwai i hōʻike ʻia, ʻo ia nā ʻano o nā nati hex kaumaha a me 8-pitch thread. 3. ʻO nā helu paʻakikī ʻo Brinell Hardness. 4. Pono nā hua i hoʻoponopono ʻia i ka carbide-solution i ka leka A - 8A a i ʻole 8MA. 5. E loaʻa i nā nati a pau ka hōʻailona hōʻailona o ka mea hana. E kaha ʻia nā hua ʻai ma ka ʻaoʻao hoʻokahi e hōʻike i ka pae a me ke kaʻina hana o ka mea hana. ʻAʻole ʻae ʻia ka mākaʻikaʻi ʻana i nā pā wīwī a i ʻole nā ʻaoʻao e pili ana ke ʻole i ʻaelike ʻia ma waena o ka mea hana a me ka mea kūʻai aku. ʻO nā hua i uhi ʻia me ka zinc he asterisk (*) i kaha ʻia ma hope o ka hōʻailona papa. ʻO nā hua i uhi ʻia me ka cadmium he hōʻailona hoʻohui (+) i kaha ʻia ma hope o ka hōʻailona papa. 6.
