Ntoo tau siv ntau pua xyoo. Qhov nrov ntawm cov khoom los ntawm nws tsis hloov. Tsuas yog cov txheej txheem thev naus laus zis hloov pauv - thiab txawm tias tom qab ntawd tsuas yog me ntsis. Fais fab saws yog siv tsis siv tes sawing, tab sis feem ntau woodworking yog tseem ua los ntawm tes.
Txawm tias peb cov yawg koob tau siv hauv kev tsim kho lub cav sawn rau hauv txheej - cov laug cam. Cov thev naus laus zis niaj hnub no tau ua rau nws ua tau kom lawv smoother, los tsim ib qho kev faib tawm. Thaum lub sij hawm pib sawing ntawm ib lub cav, ib tug unedged board tau txais. Nws lub npe (los ntawm kev pom zoo) qhia tias muaj cov tawv ntoo ntawm sab sab. Unedged board yog cov khoom tseem ceeb ntawm kev ua ntoo. Nws tuaj yeem siv rau qee qhov haujlwm ntxhib nrog rau kev ua haujlwm ntxiv.
Unedged board txawv raws qib:
- 0 (A) qib - cov rooj sib koom ua ke uas tsis muaj pob thiab lwm yam tsis xws luag. Feem ntau siv rau hauv cov rooj tog tsim khoom lossis koom nrog.
- 1 (B) qib - tsis muaj rot, kab ntoo, xiav, tawg. Cov khoom no yog siv rau hauv kev tsim kho.
- 2 (C) qib - wane (muaj cov tawv tawv tsis tau txiav) txog li 10% ntawm tag nrhothaj tsam ntawm lub rooj tsavxwm. Lawv tau siv rau hauv cov haujlwm uas cov yam ntxwv zoo nkauj ntawm cov khoom tsis tseem ceeb (battens, truss systems, thiab lwm yam).
Nyob ntawm ntau yam, tus nqi kuj hloov. Ib lub voos xwmfab ntawm lub rooj tsavxwm uas tsis muaj kev sib tw ntawm qib 2 yuav raug nqi tsawg dua li cov khoom siv qib siab. Txhawm rau xaiv cov khoom zoo, koj yuav tsum paub seb yuav nrhiav dab tsi. Cov khoom yuav tsum tsis txhob warped: nws cov duab yuav tsis zoo li ib tug arc, muaj twisting los yog roundness. Ib qho tshwm sim zoo sib xws tshwm sim nrog kev khaws cia thiab ua cov ntoo tsis raug. Unedged board yuav tsum tsis muaj chips thiab potholes. Qhov no yuav ua rau nws nyuaj rau kev ua haujlwm ntxiv, tuaj yeem ua rau cov khoom zoo li qub.
Ua tib zoo mloog rau tus lej ntawm lub pob. Lawv khoov cov fibers, nws thiaj li khoov ob lub rooj tsavxwm thiab cov khoom tsim los ntawm nws. Cov pob txha tsawg dua, qhov zoo ntawm lub rooj tsavxwm. Yuav tsum tsis muaj qhov sib sib zog nqus ntawm qhov chaw. Qhov no yuav txo tau lub neej ntawm cov khoom.
Thaum xaj, koj yuav tsum paub qhov tuab, dav thiab ntev ntawm cov ntoo xav tau. Lub thickness ib txwm ntawm unedged boards yog 25, 30, 40, 50 mm, tab sis yog hais tias koj xav tau lwm yam tsis, ib tug neeg ntau lawm yog ua tau. Qhov dav ntawm lub rooj tsavxwm feem ntau yog tus qauv thiab yog 150 hli, tab sis txawm tias qhov tshwj xeeb no tuaj yeem ua tau. Tseem muaj cov boards uas tsis tau ntsuas. Lawv muaj ib tug ncaj ntau yam ntawm parameters. Piv txwv li, hauv ib pawg yuav muaj cov laug cam nrog qhov dav ntawm 120 thiab 150 mm.
Qhov ntev ntawm txhua yam khoom siv feem ntau yog li ntawm 4 txog 6 meters. Ntawm tag nrho cov no parameter thiabnyob ntawm hom ntoo thiab tus nqi ntxiv.
Lumber siv rau kev tsim kho feem ntau yog ua los ntawm cov ntoo mos. Qhov no yog vim lawv cov kev ua tau zoo thiab tus nqi qis. Cov ntoo deciduous kuj siv rau kev kho kom zoo nkauj. Cov khoom no twb kim dua: ntoo tsis tshua muaj, thiab, raws li txoj cai, nws yog ib qho nyuaj rau txheej txheem. Lub unedged board yog tsis muaj kev zam. Tus nqi rau ib lub voos xwmfab ua los ntawm cov ntoo ntoo yog qis dua tib qib ntawm lub rooj tsavxwm, tab sis ua los ntawm linden.
