1.Bophara ba lehare la sehlopha

Bophara ba lehare ke tekanyo ea ho tloha holimo ho leino ho ea moeling o ka morao oa lehare. Li-blades tse pharaletseng li thata ka kakaretso (tšepe e ngata) 'me li atisa ho latela hantle holim'a mabili a sehlopha ho feta li-blades tse moqotetsane. Ha ho seha thepa e teteaneng, lehare le pharaletseng le na le bokhoni bo fokolang ba ho kheloha hobane qetellong ea morao, ha e le sehiloeng, e thusa ho tsamaisa karolo e ka pele ea lehare, haholo-holo haeba tumello ea lehlakore e sa feteletse. (E le ntlha ea ho buuoa, re ka bitsa lehare le bophara ba 1/4 ho isa ho 3/8 "lehare la "bophara bo bohareng".

Tlhokomeliso e khethehileng: Ha u sakha lepolanka hape (ke hore, ho etsa hore e be likotoana tse peli tse lekanang le halofo ea pele), lehare le tšesaane le tla khaola ho feta lehare le pharaletseng. Matla a ho itšeha a tla etsa hore lehare le pharaletseng le khelohe ka thōko, ha ka lehare le moqotetsane, matla a tla le sutumelletsa morao, empa eseng ka thōko. Sena ha se se ka lebelloang, empa ehlile ke 'nete.

Li-blade tse moqotetsane, ha li seha mothipa, li ka khaola mothipa o monyane haholo ho feta lehare le sephara. Ka mohlala, lehare le bophara ba ¾-inch-wide le ka khaola radius ea 5-1 / 2-inch (hoo e ka bang) ha lehare la 3/16-inch le ka khaola radius ea 5/16-inch (hoo e ka bang boholo ba dime). (Tlhokomeliso: Kerf e etsa qeto ea radius, kahoo mehlala ena e 'meli ke litekanyetso tse tloaelehileng. Kerf e pharaletseng, e bolelang sawdust e ngata le sekoti se sephara, e lumella li-radius cuts tse nyane ho feta ka kerf e moqotetsane. Leha ho le joalo kerf e pharaletseng e bolela hore likarolo tse otlolohileng li tla fetoha. e thata le ho lelera ho feta.)

Ha ke sakha lifate tse thata le lifate tse bonolo tse teteaneng tse kang Southern yellow pine, ke rata ho sebelisa lehare ka hohle kamoo ho ka khonehang; lehong le tlaase-tlaase le ka sebelisa lehare le moqotetsane, haeba le lakatsa.

2.Band lehare botenya

Ka kakaretso, ha lehare le le letenya, ho na le tsitsipano e eketsehileng e ka sebelisoang. Li-blades tse teteaneng le tsona ke li-blades tse pharaletseng. Khatello e eketsehileng e bolela ho khaola ho otlolohileng. Leha ho le joalo, li-blades tse teteaneng li bolela sawdust e ngata. Li-blades tse teteaneng le tsona li thata haholo ho kobeha ho pota-pota mabili a lihlopha, kahoo baetsi ba li-bandsaws ba tla hlalosa boholo ba botenya kapa botenya. Mabili a mabanta a manyane a manyane a hloka li-blades tse tšesaane. Mohlala, lebili la bophara ba lisenthimithara tse 12 hangata le na le lehare la botenya ba lisenthimithara tse 0.025 (boholo) bo bolelele ba lisenthimithara tse ½ kapa ho feta. Lebili la bophara ba lisenthimithara tse 18 le ka sebelisa lehare le letenya la 0.032-inch le bophara ba ¾ inch.

Ka kakaretso, li-blades tse teteaneng le tse pharaletseng e tla ba khetho ha u sakha patsi e teteaneng le meru e nang le mafito a thata. Patsi e joalo e hloka matla a eketsehileng a lehare le letenya, le sephara ho qoba ho robeha. Li-blades tse teteaneng le tsona ha li khelohe hanyenyane ha li sakha bocha.
