Inanahi nei, katahi ano matou ka mutu te uta i tetahi huinga miihini tuhi waea Torotika;

Ko te miihini tuhi waea tika, kua whakawhanakehia mo te tuhi tika, te whakaheke ranei i te waea kore utu kia pai ake ai te utu, i hangaia e matou kia rite ki te tono a nga kaihoko;

Ko te diameter waea uru 5.5mm, ko te diameter waea putanga he 1.6mm mo te hanga mata paiherea;

Kei te hiahia hoki nga kaihoko ki te hanga whao, me waea 3mm, 4mm, 5mm, na reira i whakarite ano matou i te hangai tuhi mo ratou hei otinga rereke;

Ko nga taputapu awhina penei i te pupuhi:

Tuhi utu waea, mihini matā, mihini tango waea, mihini tohu mahunga, me te miihini reke;

Ko tenei raina tuhi waea tika, he nui ake te hanga, a he pai te kounga waea kua oti mo te hanga mata paiherea;mai i te 5.5mm tika ki te 1.6mm karekau he take ma te oumu whakangao, engari he iti te utu o tenei raina, no reira he pai mo nga kaihoko he teitei ake nga taputapu whakaputa, me te nui o te tahua;

Mena he iti to tahua, ka taea e koe te haere mo te miihini tuhi waea mo te momo pulley, he mea rongonui ano, mai i te 5.5-1.6mm me tuhi mai i te 5.5-2.0mm i te tuatahi, katahi ka mau ki roto i te oumu annealing, a muri ake, whakamahia te wai. hanga waea tank miihini tuhi mai i te 2.0mm ki te 1.6mm;

Mena kei a koe he mahere, tukuna he patai me to hiahia mo te diameter waea whakauru me te diameter waea whakaputa, ka whakaratohia e matou he otinga whaitake;
