Ka whakamahia e te miihini whakapiri taha wera nga rakau hei whakamaroke me te whakamakuku i nga mea maku i te rangi, ka mimiti haere te makuku, ka iti haere te rahi me te rōrahi. Ko tenei ahuatanga e kiia ana ko te whakaheke-iti, he mea whakamaroke te miihini whakakikorua i te taha o te waiariki i te hau makuku. Ka mimiti i te makuku ka pupuhi te rahi me te rahi. Ko tenei ahuatanga ka kiia ko te pupuhi.
He rereke te paheketanga o nga momo rakau. Ahakoa te momo rakau kotahi he rerekee i waenga i te roha poutū me te whakapae me te whakahekenga, ko te ahunga whakapae he tohu radial me te chordwise. Ko te rakau o te miihini whakapiri taha he iti te whakahekenga roa, he 0.1%. Ka taea te waiho. He nui te roha taha taha o te rakau o te miihini whitiki tapa, ina koa ko te aho-ki-maroke ko te 6- 12%, ka heke te diameter o te kai ki te 3-6%. Ko te tere o te pupuhi o te rakau karekau e rite, ka puhoi haere, ka heke haere.
I muri i te whakamaroketanga o te rakau o te miihini riipene taha, ka pahekeheke. Nā te rerekētanga o te radial me te chordwise shrinkage, ka huri te rakau i tona ahua taketake, ka puta he pakanga, he piko o te rohe, he kopikopiko, he parepare-parirau, he kapiti poutū.
