Ngati mwasankha kutenga phindu lopindulitsa ndikuphunzira zamatabwa, choyamba muyenera kugula chida chocheka. Kwa izo n'zotheka kunyamula zingwe ndi zisalu za mawonekedwe osiyanasiyana ndi kukula kwake.
Posankha chida, aliyense watsopano adzadabwa ndi mitundu yosiyanasiyana ya chisels m'masalefu.
Mitundu ya zisumbu za kujambula mitengo
Tiyeni tiwone mitundu yambiri ya chisels zomwe zingakhale zothandiza pakuzindikira luso la kujambula:
- Zilonda zamtunduzi - zimagwiritsidwa ntchito pa mitundu yosiyanasiyana ya ulusi, makamaka ngati chida chothandizira. Kuwongolera kwawo sikudutsa 18-20 °;
- zida zamatabwa zojambula matabwa - zomwe zimafala kwambiri. Iwo akhoza kukhala otsetsereka, osakanikirana kapena otsika;
- Chomwe chimatchedwa klukarzy ndi chofunikira, kuti pamene mukugwira ntchito ndi ndege musaigwire ndi chogwirira. Mbali ya chisels imeneyi imapangidwira bwino, ndipo iwowo ndi ofooka, amtundu umodzi kapena amodzi;
- Zisumbu zamakono, zomwe zimatchedwa geymusami, zimagwiritsidwa ntchito makamaka popanga sampuli zofanana ndi V. Njirayi imagwiritsidwa ntchito popanga ulusi. Mng'alu pakati pa m'mphepete mwa geismus imasiyanasiyana kuyambira 50 mpaka 70 °;
- Pofuna kudula mitsempha yochepa, chisel-chisels zidzakwanira. Kunja, iwo amawoneka ngati maselo amtundu wambiri, ndipo mbiri yawo imayenera kulumikizana ndi gawo la mitsempha;
- Nsalu za chisel zimakhala zokonzeka bwino, zopangidwa ngati bowa. Zili zofunika ngati mukufunikira kufotokoza tsatanetsatane kapena kudula thumbnail pogwiritsa ntchito ntchito yolemba;
- kwa ulusi wambiri ndi kuyeretsa malo ovuta kufika
msomali wa chisel, panja ndikukumbutsa kwenikweni chikhomo. Mitundu ina iwiri ya khalapik ndi lupanga ndi tsamba, zomwe zimafunika kuti zikhale zowonongeka komanso zowonongeka.
Pogwiritsa ntchito zipangizo zopangidwira, zida zabwino kwambiri zojambula matabwa zimaganiziridwa nthawi zonse. Ganizirani kuti nsalu zamatabwa zojambula mitengo ndi zabwino bwanji, mukhoza kungodziwa zomwe zikugwiritsidwa ntchito. Komanso, zimadalira mtundu wa ulusi (zamakono, zojambulajambula, ndi zina zotero).
