Chikumbiro:InvarInoshandiswa kugadzikana kwakanyanya kwezvinhu zvinodikanwa, zviine zviridzwa zvakanyatsoitika Mukuongororwa kwepasi, kana wekutanga-kuraira (yakakwirira-chaiyo) kukwirira kweKumanira kunofanirwa kuitwa, matanda ekumusoro anoshandiswa anogadzirwa kubva kumhanyi, panzvimbo yehuni, fiberglass, kana mamwe masimbi. Invhan yemhanzvi yakashandiswa mune dzimwe pistons kudzikamisa kuwedzera kwavo kwekuwedzera mukati memasirinda avo.
