Kulwakhiwo lwentsimbi kunye neeprojekthi zokufulela intsimbi, izikrufu{0}}zokuzibhobhoza zilindeleke ukuba zigqobhoze iipleyiti zentsimbi ngokufanelekileyo ngaphandle{1}}kokugrunjwa kwangaphambili. Ngokwemigangatho yovavanyo lwe-JIS, ukusebenza kokomba kuvavanywa ngokusekwe kubukhulu beplate, ixesha lokomba, umthwalo omkhulu, kunye nesantya sokujikeleza.
Uvavanyo lwamva nje lweshishini lubonisa ukuba ukhetho olungalunganga lwendawo yokubhola luhlala lukhokelela kwixesha lokomba eligqithileyo, ukutshisa kakhulu, kunye nokunxitywa kwezixhobo kwangaphambi kwexesha. Oku akuchaphazeli nje ukufaneka kofakelo kodwa konyusa umngcipheko wokwaphuka kwencam ye-drill ngexesha lokuqina okuphezulu{1}}kwivolyum.
Idatha yesalathiso ye-JIS ibonisa ngokucacileyo ukuba ubungakanani be-screw eyahlukeneyo kunye neendawo zokubhola ziyilelwe ubuninzi bentsimbi ethile. Ngokomzekelo, amacwecwe ensimbi amancinci afuna isantya esikhawulezayo sokugaya kunye nokungena okuzinzile, ngelixa iiplati zetsimbi ezityebileyo zifuna iingcebiso eziqiniweyo kunye ne-RPM elawulwayo ukugcina ukuzinza.
Kubavelisi kunye neekontraka ezikhonza kwimarike yaseMzantsi Melika, ukuqonda le migangatho kunceda ukunciphisa ukusilela kokufakela kunye nokuphucula umgangatho weprojekthi ngokubanzi. Njengoko izakhiwo zentsimbi kunye neenkqubo zokuphahla ziqhubeka nokuguquka, ukuthotyelwa kwemigangatho yokuvavanya eyaziwayo kubaluleke kakhulu.
