Magacaabista habkan ugu fudud ee loo yaqaan 'twlepad' si fudud loogu magac daray barandhada caadiga ah ee baradhada caadiga ah. Mahadsanid isaga, waxaa ku yaal jaakad wax qabad oo jilicsan oo hooseeya oo digriiga guluubyada, shaqada lafteeda ayaa si fudud u fududaanaysa, waxsoosaar badan oo si dhakhso leh usocdaa.
Dalku wuxuu dhacaa inta lagu gudajiro dhaqdhaqaaqa: Baradhadu ka soo baxdo ka soo qaad masaar ku yaal hal hoos udhaca giraangiraha ku dhaca giraangiraha - oo is-hel digaaga.
Gawaarida "abuurka" waxay ka kooban tahay saddex qaybood - laba disc oo bir ah oo leh jeex jeex jeex jeex jeex jeex jeexjeexay iyo dhexdhexaad, oo laga jaray 60 mm qaro weyn (ama ka dhaliyay khafiif ah). Marka loo eego dusha sare ee diskiga alwaax, jeexihii semicircular-ka ayaa la sameeyaa, oo u dhigma cabirka baradhada ugu weyn ee la kariyey in la dego.
Bunds-ka waxaa lagu dhejiyaa giraangiraha. Waxaa laga samayn karaa plywood oo leh qaro weyn oo ah 10 mm ama laqabsashada baaldigan balaastigga ah, goynta godka hoose ee u dhigma ceelka giraangiraha.
Qaybta hore ee giraangiraha ayaa daboolay gaashaam-gaashaandhiga wareegaya ee ka hortagaya luminta qaaxada ceelasha ka hor intuusan ku soo xiriiro ciidda. Sidaa darteed in wax la beero ma waxyeelleeyaan, salka hoose ee riphter-ka ayaa la dhigay caws caag ah.
