• Ebisumuluzo bya safety chuck ebitikkiddwa mu spring ne switch eziyimiriza okugulu-paddle: Kozesa ebisumuluzo bya lathe chuck ebyefulumya era oteeke ku maviivi agakola paddle off-switches ku table saws.

Ebibuuzo ebitera okubuuzibwa¶

Lwaki tolina kussa lunwe olusaliddwa butereevu ku ice oluvannyuma lw’akabenje k’okusala emmeeza?¶

Okuteeka engalo oba engalo ensajja esaliddwa butereevu ku ice cubes, freezer packs, oba ice omukalu kireetera emisuwa emigonvu, obusimu, n’obutoffaali bw’olususu munda mu digito okufuuka freeze ebikalu, ne bikola microscopic ice crystals ezikutula ebisenge by’obutoffaali ne zisaanyaawo enkalakkalira endothelium y’emisuwa (frostbite). Ebitundu bwe bimala okufuuka bbugumu ku ice obutereevu, abasawo abalongoosa abatonotono tebasobola kuddamu kuteekawo kutambula kwa musaayi era digito tesobola kuddamu kusimbibwa. Bulijjo ekitundu ekisaliddwa kizinge mu gaasi omuyonjo afukiddwako katono n’omunnyo oba amazzi ga ttaapu agataliimu buwuka, okisibe munda mu kaveera akakalu, era otengejja ensawo eyo essiddwa waggulu ku ntamu ya ice n’amazzi agannyogoga okunyogoza ekitundu ekyo mu ngeri ey’obukuumi okutuuka ku diguli nga 4 Celsius (39 degrees Fahrenheit) nga togifudde.

Lwaki kigaaniddwa ddala okwambala ggalavu z’omulimu ng’okola ekyuma ekikuba ebyuma oba ekyuma ekisima, ne bw’oba ​​okwata ebyuma ebisongovu?¶

Bw’oba ​​okozesa ekintu eky’omu ngalo oba ng’okwata ebyuma ebiyimiridde, ggalavu za Kevlar ez’amaliba oba ezitasala zikuuma olususu lwo okuva ku bbugumu ensongovu. Naye okumpi n’ekyuma ekizimbulukuka ekirina amaanyi nga ekyuma ekikuba lathe chuck, lead screw, oba drill press bit, ggalavu zifuula ekintu ekitono eky’olususu ne kifuuka okutemebwako okw’akatyabaga oba okuzingibwa mu ngeri ey’akatyabaga. Singa olususu olutaliiko kintu kyonna lusiimuula ku spinning drill bit oba chuck jaw, lufuna okwokya okw’amangu okw’okusikagana oba okukutuka ekivaako okuvaamu amangu reflex. Singa olugoye olulukibwa oba fiber ya glove ey’amaliba ekwata ku linnyo oba burr eriwuuta, amaanyi amangi ag’okusika ga glove gagiremesa okukutuka nga tezikutuse, ne zisika engalo z’omukozi, omukono n’omukono gwonna mu shaft ekyukakyuka nga torque ennene mu bbanga eritakka wansi wa kwata ya sikonda.

Kiki ekivaako disiki esala angle grinder okubwatuka, era lwaki disiki ennene eyakaddiwa ya bulabe ku grinder entono?¶

Disiki ezisalako ezisiigibwa nga zisibiddwa resin zikwatibwa wamu n’akatimba ka fiberglass akakoleddwa yinginiya okugumira sipiidi ey’enjawulo ey’oku bbali ku bbali, mu ngeri entuufu mita 80 buli sikonda (mayiro 180 buli ssaawa). Olw’okuba disiki ennene eya mmita 180 (yinsi 7) oba mmita 230 (yinsi 9) erina okwetooloola obugazi, etuuka ku sipiidi eyo esinga obunene ey’obukuumi ku rim ku 6,500 ku 8,500 RPM zokka, so ng’ate akatono aka mmita 115 (yinsi 4.5) yeekulukuunya ku sipiidi 11,000 okutuuka ku 13,300 RPM. Omukozi bw’aggyawo omukuumi okuva mu kawundo akatono aka RPM ennyo okuteeka disiki ennene (ne bwe yali eyambala wansi mu sayizi, ng’ekituli kyayo eky’okuteeka wakati n’okuluka kwa fiberglass byanafuwa olw’okukozesebwa ennyo emabegako), sipiidi esukkiridde ey’okuzimbulukuka ereeta amaanyi ag’okuwunyiriza agasukka ekkomo ly’enzimba y’ekiyungo kya resini, ne kitulisa nnamuziga mu shrapnel ezisukkulumye ku maloboozi.

Singa omukono gwa mukozi munnange guzingibwa ku lathe spindle ne guyimiriza ekyuma oba emidaala, lwaki sikyusa switch ya motor mu reverse okuzisumulula?¶

Motors za lathe z’amakolero ne geared headstocks zikola massive starting torque amaanyi g’amasannyalaze ag’amangu bwe gassibwako. Singa ossa amaanyi mu mmotoka mu ngeri ey’okudda emabega ng’omukono, ekibegabega oba enkokola y’essaati ya mukozi munno eyamenyese ezingibwa nnyo ku chuck oba workpiece, oba olina obuyinza obutono ku bbanga oba effujjo spindle gy’ekyuka; okubwatuka kw’amasannyalaze okumala ekitundu kya sikonda kuyinza okukyusakyusa amagumba agamenyese mu ludda olulala, okusalako omusuwa gw’omukono ogunyigirizibwa, oba okukutula ensingo y’omuntu ayisiddwa ku kitanda kya lathe. Bulijjo ggyamu ddala amasannyalaze, kyusa levers z’okutambuza amasannyalaze mu headstock mu mechanical neutral, era oba olinde abakugu mu kutaasa omuliro oba kyusa chuck mpola n’obutundutundu bw’emikono obwa sentimita omulundi gumu ng’osala engoye ezinywezeddwa n’ebisala eby’obuvune.

Ekitabo kino kiwa amawulire agakwata ku kwetegekera mu mbeera ez’amangu n’obujjanjabi obusookerwako ku bubenje bw’ebyuma by’omusomo era tekidda mu kifo ky’okutendekebwa mu ngalo mu by’okwerinda by’ebyuma oba obujjanjabi obw’obujjanjabi. Lowooza ku ky’okukola omusomo ogukkirizibwa ogw’obujjanjabi obusookerwako, CPR, ne Stop the Bleed tourniquet okuva mu Red Cross, St John Ambulance, American College of Surgeons, oba ekitongole kyo eky’ebyokwerinda mu ggwanga.
