3. Umutwe wumusumari uragwa: Nyuma yo kuzunguruka, umutwe wa mandel ntushobora gupfunyika ukagwa mumubiri wa rivet.
Impamvu zo kugwa kumutwe wumusumari ni: diameter yumutwe wa mandel nini cyane;umubiri wa rivet ni mugufi kandi ntabwo uhuye nubunini bwa riveting.
4. Kuvunika k'umubiri uzunguruka: Nyuma yo gukurura ibizunguruka, umubiri uzunguruka ufite ibice birebire cyangwa byacitse burundu.
Impamvu zitera kumeneka kumubiri ni: ubukana bwumubiri uzunguruka ni mwinshi cyane cyangwa ntabwo ubushyuhe buvurwa nyuma yo gufatana;diameter yumutwe wa mandel ni nini cyane;ibirimo umwanda wangiza mubintu byumubiri byumubiri ni muremure cyane, cyangwa hariho interlayers.
