1.Band blade width

Upamhi hwebadza chiyero kubva pamusoro pezino kusvika kumucheto kumashure kwebadza. Iwo mablades akafara akaomarara (yakawanda simbi) uye anowanzo kuteedzera zvirinani pamavhiri ebhendi pane mashizha matete. Kana uchicheka zvinhu zvakakora, blade yakafara ine kushomeka kwekutsaukira nekuti iyo yekumashure inopera, kana iri mukucheka, inobatsira kutungamira kumberi kweblade, kunyanya kana kucheneswa kweparutivi kusiri kuwandisa. (Sechirevo chekutaura, tinogona kudana blade iyo 1/4 kusvika 3/8 inch muhupamhi "blade yepakati" blade.)

Chinyorwa chakakosha: Paunenge uchicheka patsva chidimbu chehuni (kureva, kuchigadzira kuita zvidimbu zviviri hafu yakakora seyepakutanga), blade nhete inocheka yakatwasuka kupfuura blade yakakura. Simba rekucheka rinoita kuti chipande chakafara chitsaukire kumativi, nepo nebadza nhete, simba rinorisundira kumashure, asi kwete kudivi. Izvi hazvisi izvo zvingatarisirwa, asi ichokwadi.

Mashizha akatetepa anogona, kana achicheka curve, kucheka radius curve diki pane blade yakakura. Semuenzaniso, ¾-inch-yakafara blade inogona kucheka 5-1/2-inch radius (inenge) nepo 3/16-inch blade inogona kucheka 5/16-inch radius (inenge saizi yedime). (Cherechedza: Kerf inosarudza radius, saka mienzaniso miviri iyi ndiyo mikoshero yakajairika. Kerf yakafara, zvichireva kuti sawdust yakawanda uye nzvimbo yakapamhama, inobvumira kucheka kweradius kudiki pane nekefi nhete. Asi kerf yakakura zvinoreva kuti kucheka kwakatwasuka kunenge kuri kushata uye kuva nekudzungaira kwakawanda.)

Kana uchicheka miti yakaoma uye yakakwirira density softwoods seSouthern yellow pine, zvandinoda kushandisa zvakafara blade sezvinobvira; pasi density huni inogona kushandisa blade yakamanikana, kana ichidiwa.

2.Band blade ukobvu

Kazhinji, iyo yakakora iyo blade, iyo yakanyanya kushushikana inogona kuiswa. Mashizha akakora ndiwo zvakare mablades akafara. More tension zvinoreva kucheka kwakatwasanuka. Zvisinei, mashizha akakora anoreva kuwanda kwesawdust. Mashizha akakora akanyanya kunetsa kukotama achitenderedza mavhiri ebhendi, saka vazhinji vanogadzira mabhandeji vanotsanangura ukobvu kana ukobvu. Mavhiri madiki dhayamita bhendi anoda mashizha matete. Semuenzaniso, 12-inch diayamita vhiri rinowanzo shongedzerwa ne 0.025-inch ukobvu (maximum) blade iri ½ inch kana nhete. Gumbo re 18-inch diayamita rinogona kushandisa 0.032-inch gobvu blade iro rakafara ¾ inch.

Kazhinji, mashizha akareba uye akafara ndiwo achave akasarudzwa paunenge uchicheka matanda akaoma uye matanda ane mafundo akaoma. Huni dzakadai dzinoda simba rakawedzerwa rebadza rakakora, rakafara kuti risatyoke. Mashizha akakora zvakare anotsvedza zvishoma kana uchicheka patsva.
