Ua txhua yam ntawm cov ntawv xuas tes ua yuav pab koj tus menyuam tsim kom muaj lub cev zoo, thiab qhov no, yuav ua rau nws muaj qhov zoo rau nws qhov kev txhim kho tag nrho: tsim kev hais lus kom raug, txawj ntse, saib xyuas, thiab lwm yam
Koj tuaj yeem ua ntau yam khoom siv tes ua tawm los ntawm daim ntawv, tab sis nyob rau Hmo ua ntej Xyoo Tshiab - lub xyoo ntawm Dab Hluav Taws Xob, khoom siv tes ua nyob rau hauv daim ntawv ntawm no tshwj xeeb tsiaj yog nrov heev. Muaj ntau cov tswv yim los ua ib tus liab tawm ntawm daim ntawv, hauv qab no yog ib qho yooj yim tshaj plaws, hauv qab no uas koj yuav tau txais tus tsiaj ntxim hlub zoo nkauj.
Koj yuav xav tau:
- ib daim ntawv ntawm xoob xoob;
- felt-taub cwj mem;
- txiab.
Siv ib daim ntawv, thiab yog tias nws muaj tus qauv duab plaub (A4 hom), tom qab ntawd ua cov duab plaub fab tawm ntawm nws. Thaum ua tiav lub xwmfab, muab tso rau pem hauv ntej ntawm koj nrog ib qho ntawm cov ces kaum rau koj thiab muab nws tso rau hauv ib nrab kom tsim ib daim duab peb sab isosceles.
Tom ntej no, quav tus duab nyob rau hauv ib nrab dua, rau qhov no, ua ke sab xis ntawm daim duab peb sab nrog sab laug.
Tsa rau sab saud ntawm qhov chaw ua haujlwm thiab kho nws cov ces kaum ntse nrog lwm cov ces kaum ntse. Nco ntsoov tias thaum muab cov npoo ntawm daim duab no "faib rau" rau ob sab thiab nws hloov mus ua plaub fab.
Tig qhov khoom ua haujlwm dhau mus rau sab tod (sab hauv tawm). Siv cov duab los ntawm lub ces kaum ntse (muaj tsuas yog ib qho) thiab txuas nws nrog lub kaum sab xis uas tau taw qhia rau hauv koj txoj kev coj. Tib txoj kev ib yam li nyob hauv qib dhau los, nco ntsoov tias cov npoo ntawm daim duab thaum khawm "seem" hauv cov lus qhia sib txawv. Hlau tag nrho cov quav ntawm lub workpiece kom huv si.
Tso cov khoom siv tes ua rau ntawm koj xub ntiag, tom qab ntawd khawm sab sab xis ntawm nws, nrog rau sab laug sab dua kom lawv dhau raws seem hauv nruab nrab ntawm daim duab. Khoov sab rau saum toj. Hlau tag nrho cov quav zoo, tom qab ntawd ncaj tag nrho cov kauj ruam uas tau ua tiav. Nrog koj sab tes laug, lob sab hauv qab ntawm daim duab thiab nqa nws nce, thaum txhawb nqa tus qauv txuas nrog koj sab tes xis kom nws tsis txhob poob. Yog li ntawd, koj yuav tsum tau txais cov hauv qab no.
Tig lub workpiece nrog sab tsis ncaj ncees tig rau koj thiab rov ua tag nrho cov kauj ruam dhau los.
Dlhos cov kab qis dua ntawm cov rhombus tawm nrog qhov nruab nrab ntawm daim duab. Tig qhov ua haujlwm dhau ntawm lub ntsej muag mus rau sab tsis huv thiab rov ua cov kev siv dag zog.
Tom ntej no, tig mus rau daim duab 180 degrees, nrog koj sab tes laug tuav tus qauv los ntawm nws sab sauv, nrog koj sab tes xis, coj ib sab kaum ntawm qhov chaw ua haujlwm thiab nqa nws sab. Hlau quav. Nrog txiab txiav, txiav cov ceg ntawm ib nrab ntawm ob lossis peb sab saud ntawm tus kheej. Puab lub taub hau thiab pob ntseg.
Txiav qhov qis dua ntawm qhov workpiece nrog txiab hauv nruab nrab mus rau theem ntawm tus tsiaj lub puab tsaig. Khoov lawv nyob rau hauv ntau cov lus qhia, sib sau ua tus tes taw. Ua tib yam nrog ob sab ceg pem hauv ntej. Hauv txoj hauj lwm dab tsi los siv lawv yog koj. Thaum kawg, kos lub qhov muag thiab qhov ntswg ntawm tus tsiaj.
