Ua ntej, forged trowels. Forging yog thaum lawv ua kom sov ib daim hlau thiab rauj nws ua cov duab. Xav tias Blacksmiths - tib lub tswv yim. Qhov no ua rau cov hniav super muaj zog vim tias nws yog ib daim ntawv ruaj khov. Tsis muaj ib qho tsis muaj zog, tsis muaj nqaws. Kuv forged carbon steel trowel muaj cov hniav uas tuab thiab ruaj khov {}} tuaj yeem lis cov hlua khi, scraping txau, txawm tias kev sib xyaw ua ke. Tus kov yog feem ntau txuas nrog lub zog muaj zog, tsis kua nplaum lossis pheej yig screads. Forged trowels kuj muaj qhov zoo dua "xav"- Daim ntawv cug, uas ua rau lub txaj pw pob qij txha. Downside? Lawv kim dua - feem ntau 30-50. Tab sis lawv tau kawg txoj kev ntev dua, yog li nws muaj nqis nws.
Tom qab ntawd muaj welded trowels. Cov no yog ua los ntawm vuam cais cov hniav cais rau ib tug kov. Yog li muaj ib leeg leeg uas cov hniav thiab kov tau ua tiav - yog qhov chaw tsis muaj zog. Kuv muaj ib lub trowel weldel qhov twg cov hniav tuaj xoob ntawm qhov kov tom qab 6 lub hlis. Koj tuaj yeem qhia ib qho welded ib qho vim tias tus tuav zoo li nws "daig" rau cov hniav, tsis yog ib feem ntawm nws. Welded hniav yog tseem ua tau nyias, yog li lawv khoov tau yooj yim dua. Kuv tau sim coj mus rhaub ib lub cib nrog kuv cov trdel weldel ib zaug, thiab cov hniav khoov- yuav tsum muab pov tseg. Lawv nyob nraum pheej yig dua, txawm hais tias - Feem ntau 15-25. Tab sis koj yuav hloov lawv txhua xyoo lossis ob xyoos.
Lwm qhov sib txawv? Hnyav thiab tshuav nyiaj li cas. Forged trowels yog hnyav dua, tab sis balanced -}} lawv zaum tus yaum kom nyob hauv koj txhais tes. Welded trowels feem ntau saum - hnyav lossis kov} hnyav, uas ua rau lawv nyuaj rau kev tswj hwm. Kuv pom qhov tam sim no - Kuv forged trowel xav zoo li kev txuas ntawm kuv txhais tes, thaum lub welded ib qho zoo li kuv tau tuav ib qho khoom ua si.
Yog li, kom suav tau: forged trowels yog ib daim tawv, muaj zog, ruaj, thiab balanced {{muaj nqis rau cov nyiaj ntxiv. Welded trowels yog pheej yig, tab sis tsis muaj zog, nyias, thiab tsis sib xws {{10 sij hawm} lub sijhawm ua haujlwm, tab sis tsis yog siv. Yog tias koj npaj ua ib qho masonry ntau dua li ib lub ntiaj teb, mus forged.
