Amapensela awashintshanga kakhulu kule minyaka eyikhulu edlule, okungenani hhayi eye Inkampani ejwayelekile yePensela, Enye yezinkampani zokugcina zamapensela e-US. Ngenkathi besebenzisa ama-conveyor namanye amathuluzi ezitolo zemishini, amapensela aqoshwe lapho asenziwa ngesandla futhi enziwe ngale ndlela kusukela inkampani yavula iminyango yayo emuva ngo-1889 eJersey City, eNew Jersey.
Inqubo yokwenziwa kwamapensela ngezandla iqala nge-graphite — izingxenye zayo zibekwa, kanye nobumba, esigubhini esikhulu esijikelezayo lapho zifakwa khona ngopende ngamatshe zibe yimpuphu ecolekileyo. Amanzi abese ephonswa emxubeni, ohlanganiswa izinsuku ezintathu, emva kwalokho, amanzi akhanywe, bese eba udaka olomiswa emoyeni futhi lukhuni ngemuva kwezinsuku ezine.
Ukuxuba okumisiwe kudlulela kokunye okushaya othulini ngamanzi amaningi afakiwe ukwenza unamathisela othambile, obese ukhishwa njenge-pasta ube yizinduku ezincanyana, ezisikwa zibe ipensela ubude futhi zomiswe ngumoya kuthutha lapho ziya khona kuhhavini bese zibhakwa 1,800 F. Le nqubo yenza izinduku (ezaziwa ngokuthi imikhondo) zibe bushelelezi futhi zibe nzima- zilungele ukwenza amaphuzu okubhala.
Ngenkathi inqubo ye-graphite yenzeka, imishini isika amabhlokhi e-Incense Cedar Wood emgqonyeni wepensela awenze ama-slats abanzi anemigexo eyisishiyagalombili engajulile yobude enqanyulelwe ngamunye. Induku ye-graphite ibese ifakwa esakhiweni ngasinye nenye i-slat ebunjiwe ebekwe phezulu bese ihlanganiswa ndawonye. Lapho nje iglue selomile, ama-slats athunyelwa emshinini wokusika lapho izindwani zensimbi zisika khona izinkuni zibe yimilo eyindilinga noma enamacala ayisithupha, zikhiqize amapensela ayisishiyagalombili kusilayidi ngasinye.
Amapensela ekugcineni athola umsebenzi wopende (amajazi ayisi-5 kuye kwayi-8), athola inkampani enophawu lwefilili noma isitembu sokupenda, nebhande lensimbi (ferrule) ukufaka irabha. Ukusuka lapha, amapensela alolwa (noma cha), ahlanganisiwe futhi alungele ukuthunyelwa ezinganeni zesikole, kubadwebi nakubasebenzi bezohwebo ngokufanayo.
I-General Pencil Company iphinde ikhiqize amapensela anemibala ngendlela efanayo — kuphela esikhundleni se-graphite, basebenzisa ama-pastel ukuletha imibala ecebile negqamile. Kuyathakazelisa ukuthi akhiqiza umbala owodwa ngeviki njengoba kuthatha isikhathi esiningi ukuhlanza imishini ngaphambi kokuba kwenziwe umbala omusha. Ngemuva kokuthatha kalula ipensela elula, ngithola inhlonipho entsha etholakele ngemuva kwalokho okudingekayo ukuyenza, okuwumzamo othatha isikhathi eside ukusuka ekuqaleni kuya kumkhiqizo ophelile.
