ʻO ka hana ʻana i nā poloka hollow, nā pōhaku i puhi ʻole ʻia a me nā mea kūkulu hale hou mai ke koena ʻōpala ʻoihana i lawe mai i nā manawa hoʻomohala nui a me kahi ākea ākea. I mea e paipai ai i ka hoʻomohala ʻana i nā mea pā hou e hoʻololi i nā pōhaku lepo paʻa a kākoʻo i ka hoʻohana piha ʻana i nā koena ʻōpala ʻoihana.

ʻO ka mea mua, ʻo ka mālama ʻana i ke kaiapuni, ʻo nā mea maka i hoʻohana ʻia e ka mīkini pōhaku lepo ka pōʻino nui i ke kaiapuni i hoʻokumu ʻia e ka mining kūloko a me ka ʻeli ʻana, a loaʻa i ka mīkini brick sima kekahi mau pono no ka pale ʻana i ke kaiapuni.
ʻO ka lua, ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka pālolo

ʻO nā ʻano pōhaku sima a me nā pōhaku lepo i hana ʻia e kēia ʻano mīkini pōhaku ʻokoʻa hoʻokahi. ʻO ia nā hale a pau i hana ʻia e ka mīkini brick sima, a hiki ke hoʻohana ʻia ke kūkulu ʻana i nā ʻāpana nui ma ka pā kula.

No laila, hiki ke ʻae maikaʻi ʻia ka mīkini hydraulic cement brick e nā mea kūʻai aku. ʻO Honcha block making machinery he mea hana kūikawā i ka hana ʻana a me ka hoʻomohala ʻana i ka mīkini sima sima piha. Hoʻopuka pū mākou i kekahi mau mea kākoʻo no ka mīkini brick sima, a hana pū mākou i ka mold no nā mea kūʻai.
