Nangona sonke siyayazi into yokubumba umatshini wezitena ezingatshisiyo, abantu abaninzi abazi ukuba benze njani olu hlobo lokungunda. Makhe ndikwazise. Okokuqala, zininzi iintlobo zokubumba komatshini wezitena, ezifana nokubumba kwezitena ezingenanto, ukubumba kwezitena eziqhelekileyo, ukubumba kwezitena zombala kunye nokubumba okungafaniyo. Ngokwembono yezinto eziphathekayo, kukho iindidi ezintathu. Eyokuqala ngumngundo owenziwe ngentsimbi eqhelekileyo, eyahlulahlulwe yaba ngundo oluphezulu kunye nokungunda okungaphantsi, Elesibini lenziwe ngentsimbi ye-manganese enguNombolo 15, njengesarha yokusika ibhastile. Okwesithathu yi-zinc carbon mold, elingana neNombolo ye-65 yentsimbi ye-manganese. Okukhona iphezulu ileyibhile yemanganese, kokukhona kuqina ngakumbi amandla okumelana nokunxiba, kodwa kulula nokuba brittle. Yiyo loo nto isikhunta ngokuqhelekileyo sikwimeko engcono xa i-manganese ingama-65 kuphela. Ukuba ileyibhile iphantsi, ayinawo amandla kwaye ayigugi. Le yintshayelelo emfutshane yokubumba.
