Bowolo lokhala ndi chogwirizira (1) chokhala ndi nsonga yokhala ndi zoyikapo ziwiri zodulira (5, 5') pa ndege yayikulu (C-C), zoyikapo (5, 5) ') zimakhala ndi m'mphepete mwachidule chapakati. ndege yachiwiri wamba (E-E). Mphepete mwa nthitiyo imapanga nsonga ngati yapakati yodulira polowera chogwirira ntchito ndikuyika pakati pobowola. Pamalo otchinga, pali zitoliro ziwiri (6, 6') zomwe zimayambira kumapeto mpaka kumapeto. Mu gawo lililonse motsatira arbor, zitoliro zili diametrically moyang'anana wina ndi mzake mu ndege chubu, ndi ndege chubu mu ndege ya dziko wamba (F-F) wa mayiko awiri mbali zonse za chubu. Kufikira pa 90 °, arbor imakhala yolimba kwambiri mu ndege iyi. The ndege yachiwiri (E-E) chapakati kudula m'mphepete ndi zochokera pa ngodya pafupifupi 90 kwa lalikulu okhwima malangizo (F-F) wa dziko ndege kapena pansi mapeto a shank.

Pobowola konkriti kapena zina zotero, ndizotheka kuchepetsa kusintha kwadzidzidzi kwa dziko lobowola, ndikukhazikitsa ntchito yobowola, ngakhale kupanga tchipisi tating'onoting'ono, kuyendetsa bwino sikutsika.

Gawo laling'ono lopangidwa mokhazikika mozungulira, lokhala ndi magawo awiri odulira, komanso nsonga ziwiri zodulira zomwe zimayikidwa pakati pa gawo lalikulu la m'mphepete ndi gawo lalikulu lozungulira mbali yozungulira. chigawo chachikulu chodula ngati m'mphepete mwake, ndipo mapeto amkati mwazitsulo zazikuluzikulu zimakhala pakatikati pa kuzungulira, ndipo mapeto akunja ali pamphepete mwa kunja kwa malo ozungulira a gawo locheka.
