Mabowo oyesereraamazimitsidwa pa bolodi la madera omwe ali ndi singano kapena mpeni wagombe, koma sungatamidwe (mwachitsanzo, semi kudzera mabowo). Gawo losinthira pakati pa khoma la bodmost / Laukulu kwambiri ndi khoma la dzenje laling'ono kwambiri likufanana ndi PCB pamwamba. Gawo lolumikiza mabowo akuluakulu ndi ang'onoang'ono ndi ndege, osati ndege yokhazikika.

Countergore imagwiritsidwa ntchito kwambiri pazitsulo zazitsulo, monga aluminium gawo lapansi ndi lamkuwa. Gawo lachitsulo lili ndi mphamvu zapamwamba ndipo sizovuta kuwononga mawonekedwe a PCB.
Dzenje, monga dzinalo likutanthauza, lilinso ndi dzenje, lomwe lingadutse zinthu kapena zakumwa zosayenera,
Ntchito ndi:
a. Amagwiritsidwa ntchito polumikizana ndipo amatha kupangidwa kukhala wopindika kudzera mdzenje.
b. Pangani ma cylinders a injini za piston.
c. M'moyo, zovala ndi mathalauza omwe timavala ndi zitsanzo za mapulogalamu
Bowo lalikulu la zigawenga ndi kalasi ya Copsed Pull.
Chifukwa cha mapangidwe apadera a phazi, amatha kulumikizidwa ndi dzenje ndi mikangano yake atayikidwa m'dzenjemo.
Ubwino ndikuchepetsa msirikali wogulitsira zinthu zotere; Ngati mabowo oterewa sakopedwa pamapeto pake, imakhala kosavuta kulowa m'magawo. Inde, kusintha mobwerezabwereza kumakhudza kudalirika kwa dzenje.
Mapati oyambira akufuna mabowo amaperekedwa ndi ntchito yowonjezera, m'malo mochita ulusi.
Zina zikuluzikulu zidzawonekeranso pambuyo pake zigawo zina zikuluzikulu zikuluzikidwa, pomwe ena sadzawombedwa.

Countergore imagawika mayina atatu:
1. Bwenzi lokwanira mutu wa Freener mu bowo la gawo la gawo la gawo la mbali, lotchedwa coorbore
2. Mutu wa Freener samazimitsidwa kwathunthu mu bowo la gawo la gawo, lomwe limatchedwa Countersink
3. Mutu wa Freener sadzamira mkati mwanga, ndipo dzenje lokhalo ndi lathyathyathya limatchedwa Sosole
Kusiyana pakati pa dzenje la makonso ndi kope lokoncheke kumtunda kwa dzenje la bolt labwezeretsanso: Bowo la ma counter ndi mawonekedwe owongoka owongoka; Bowo la ma counter ndi kapangidwe ka 45, lomwe limakhala losalala kuposa dzenje.
 
Kukweza kwapamwamba kwa bowo la bolt kumatha kukhala ndi mutu wa bolt, kotero kuti mutu wa bolt sukwera kuposa malo ozungulira.
