201 simbi isina simbi
Copper Zvemukati: J4> J3> J3> J5.
Carbon Zviri Mukati: J5> J3> J3> J4.
Kuronga kuomarara: J5, J3> J3> J4.
Kurongeka kwemitengo kubva pakakwirira kusvika kuderera ndeye: J4> J3> J3, J5.
J1 (MIRY COPERS): Iyo Carbon Zvemukati yakakwirira zvishoma kupfuura J4 uye iyo mhangura yezvinyorwa zvakadzika kupfuura J4. Maitiro ayo ekugadzirisa ari kushoma panej4. Izvo zvakakodzera kuti udhevedzwe wakadzika wakadzika uye zvakadzika zvigadzirwa zvekudhirowa, zvakadai sekoronga rekushongedza, zvigadzirwa zvekushongedza, kunyura, chigadzirwa chubhu, nezvimwe.
J2, J5: Kushongedza machubhu ekushongedza zvigunwe zvichiri zvakanaka, nekuti kuomarara kwakakwira (zvese zviri pamusoro pe96 °) uye iyo mraba tube kana iyo yakacheneswa tube (90 °) inowanzo kuputika.
Maererano nelat blate: Nekuda kwekureba kwakanyanya, iyo bhodhi yemusoro wakanaka, uye kurapwa kwemukati kwakadaro se
chando, kupukuta uye kuisa zvinogamuchirika. Asi dambudziko rakakura ndiro dambudziko rakakotama, iyo bend iri nyore kuputsa, uye gorogo iri nyore kuputika. Kusarongeka kwekuwedzera.
J3 (Low Low Copper): Inokodzera machubhu ekushongedza. Kugadziriswa kuri nyore kunogona kuitwa pamusana rekushongedza, asi hazvigoneke nekuomerwa zvishoma. Pane mhinduro yekuti iyo yekufukura ndiro yakakotama, uye pane yemukati seam mushure mekutyora (dema titanium, ruvara plate, sanding ndiro, yakaputsika, yakaputirwa kunze neyemukati seam). Iyo yakanyura zvinhu yakaedzwa kukotama, 90 degrees, asi haizoenderera.
J4 (yakakwira ndarira): Iyo yekupedzisira yekupedzisira yejeri. Iyo yakakodzera kune diki diki marudzi emhando dzezvakadzika zvigadzirwa zvigadzirwa. Zvizhinji zvezvigadzirwa zvinoda kupora munyu kutora uye munyu spray bvunzo zvichazvisarudzira. Semuenzaniso, kunyura, midziyo yekicheni, zvigadzirwa zvekugezera, mabhodhoro emvura, macuum flasks, gonhi hinges, shackles, etc.
