He hononga paipa te tī, he wāhanga hono paipa hoki. E mōhiotia ana hoki kotīra whakauru paipate hononga tī rānei, te hononga tī, e whakamahia ana ki te paipa peka o te paipa matua.
He hononga paipa matū te tī, e toru ngā pūaha, arā, kotahi te tomokanga me ngā putanga e rua; e rua rānei ngā tomokanga me te putanga kotahi. E tūtaki ai ngā paipa e toru, e rite ana, e rerekē rānei. Ko te mahi matua o te tī he whakarerekē i te ahunga o te wai.
Ko te pēhi wera-toru-ara he whakawhāiti i te paraikete ngongo he nui ake i te diameter o te paraikete-toru-ara ki te rahi o te diameter o te paraikete-toru-ara, ka whakatuwhera i te kōhao ki te wāhanga o te paipa peka kua toia; ka whakamahanahia te paraikete ngongo, ka maka ki roto i te mate hanga, ka whakanohoia ki roto i te paraikete ngongo. Ka utaina te mate mō te toia o te paipa peka ki roto; ka pēhia te paraikete ngongo i raro i te mahi pēhanga. I roto i te tukanga pēhi radial, ka rere te konganuku i te ahunga o te paipa peka ka hanga i te paipa peka i raro i te totoro o te mate. Ka hangaia te tukanga katoa mā te pēhi radial o te paraikete ngongo me te tukanga totoro o te paipa peka. He rerekē i te tī pupuhi waipēhi, ka utua te konganuku o te paipa peka tī wera-pēhi e te nekehanga radial o te paraikete ngongo, nō reira ka kiia hoki ko te tukanga utu radial.
Nā te mea ka pēhia te tī i muri i te whakamahana, ka whakaitihia te taumaha o ngā taputapu e hiahiatia ana mō te hanga rauemi. He whānui te urutau o te tī pēhi-wera ki ngā rauemi, ā, he pai mō te maitai waro-iti, te maitai koranu me ngā rauemi maitai kore waikura; inā koa mō ngā tī he whānui nui me te pakitara matotoru, ko tēnei tukanga hanga te tikanga e whakamahia ana.
