Ihinduranya ry'umuvuduko rihindagurika: rishobora guhindura vuba umuvuduko w'icyuma cy'umusumeno no gusimbuza icyuma cy'umusumeno, ibyo bikaba bizigama igihe n'umurimo.
Umukingo udapfundikiye upfutse rubber: woroshye cyane gufata.

Imurikagurisha ry'ibicuruzwa
Gukoresha hacksaw:
Uruti rw'umucanga rugizwe n'uruti rufite ishusho ya I, umugozi ugoramye, icyuma kigoramye, icyuma cy'umucanga, nibindi. Impera ebyiri z'icyuma cy'umucanga zishyirwa ku ruti hakoreshejwe utubuto kandi zishobora gukoreshwa mu guhindura inguni y'icyuma cy'umucanga. Uruti rw'umucanga rushobora gukoreshwa nyuma yo gukazwa. Uduti tw'umucanga dushobora kugabanywamo utunini, turi hagati n'utworoshye hakurikijwe uburebure butandukanye bw'icyuma n'amano. Uruti rw'umucanga rufite uburebure bwa mm 650-750, naho amenyo afite uburebure bwa mm 4-5. Uruti rw'umucanga rukoreshwa cyane cyane mu gukata ibiti binini; Uruti rw'umucanga ruri hagati rufite uburebure bwa mm 550-650, naho amenyo afite uburebure bwa mm 3-4. Uruti rw'umucanga ruri hagati rukoreshwa cyane cyane mu gukata ibiti bito cyangwa tenon; Uruti rw'umucanga rufite uburebure bwa mm 450-500, naho amenyo afite uburebure bwa mm 2-3. Uruti rw'umucanga rukoreshwa cyane cyane mu gukata ibiti bito no gukata urutugu.
Kwitondera igihe ukoresha hacksaw:
1. Ishyo ry'umukero ry'icyitegererezo kimwe ni ryo ryonyine rishobora gusimburwa.
2. Ambara indorerwamo n'uturindantoki mu gihe ukata.
3. Ishyo ry'umukero riratyaye, nyamuneka ukoreshe witonze.
4. Umusatsi wo gukata si igikoresho gikingira. Ntugace ibintu bizima.
