\u00a0 \u00a0 \u00a0Les n\u00e1m dok\u00e1\u017ee poskytn\u00fa\u0165 naozaj v\u0161etko potrebn\u00e9 a aj nie\u010do navy\u0161e. Pred samotn\u00fdm vyrez\u00e1van\u00edm napr\u00edklad ly\u017eice, je dobrou pom\u00f4ckou si najprv nakresli\u0165 jej tvar. Je to jednoduch\u0161ie, ako \u00eds\u0165 na prv\u00fd kr\u00e1t \u201eokometricky\u201c, odhadom. Samozrejme, ke\u010f vyrob\u00edme piatu, tak n\u00e1kres u\u017e potrebova\u0165 nebudete. Potom to p\u00f4jde sam\u00e9. My sme ale za\u010diato\u010dn\u00edci. Na to, aby sme mohli nie\u010do kresli\u0165, potrebujeme ceruzku. Uk\u00e1\u017eem v\u00e1m teraz n\u00e1vod, ako ju \u013eahko vyrobi\u0165.<\/p>\r\n\r\n\r\n\r\n

\u00a0 \u00a0 \u00a0V jednoduchosti je kr\u00e1sa a na\u0161i predkovia poznali pyrol\u00fdzu (rozklad materi\u00e1lu bez pr\u00edstupu kysl\u00edka pomocou tepla) u\u017e d\u00e1vno. Spo\u010diatku to bolo nie\u010do medzi destil\u00e1ciou (ochladzovanie p\u00e1r na tekutinu) a skuto\u010dnou pyrol\u00edzou. Pokusmi zistili, \u017ee takto dok\u00e1\u017eu z\u00edska\u0165 u\u017eito\u010dn\u00e9 veci. Vylep\u0161ili technol\u00f3gie a za\u010dali vyr\u00e1ba\u0165 dreven\u00e9 uhlie, decht z ihli\u010dnanov a briez, alebo charcloth, zuho\u013enaten\u00fa l\u00e1tku, ktor\u00e1 zachyt\u00ed iskru. No a takisto aj ceruzku. Tieto sa robili hlavne z v\u0155bov\u00fdch kon\u00e1rikov.<\/p>\r\n\r\n\r\n\r\n

\u00a0 \u00a0 \u00a0Na v\u00fdrobu potrebujete uzatv\u00e1rate\u013en\u00fa krabi\u010dku. Samozrejme plechov\u00fa. Spravte do nej mal\u00fa dierku. Je to kv\u00f4li tlaku. Pary, ktor\u00e9 vznikaj\u00fa ako prv\u00e9, sa musia dosta\u0165 von. Vlo\u017e\u00edte do nej kon\u00e1riky. Odpor\u00fa\u010dam such\u00e9 a bez k\u00f4ry. Nie je nutn\u00e9 odrez\u00e1va\u0165 ich priamo zo stromu. Dajte krabi\u010dku do oh\u0148a, resp. pahreby. Po\u010dkajte pribli\u017ene pol hodinku a m\u00e1te hotovo. Niekto po vytiahnut\u00ed e\u0161te drievkom uzatv\u00e1ra t\u00fa dierku, k\u00fdm krabi\u010dka nevychladne. Je to zbyto\u010dn\u00e9. Bu\u010f to m\u00e1te hotov\u00e9, alebo nie. Z mojich sk\u00fasenost\u00ed je pol hodinka posta\u010duj\u00faca.<\/p>\r\n\r\n\r\n

\u00a0 \u00a0 \u00a0Tu by niekto skon\u010dil s v\u00fdrobou. Tuha je hotov\u00e1 a d\u00e1 sa s \u0148ou pekne p\u00edsa\u0165 a kresli\u0165, ale trochu \u0161pin\u00ed ruky a je ve\u013emi krehk\u00e1. Tak som dostal n\u00e1pad. Dreven\u00fd obal. Napadla v\u00e1m baza? Aj mne. Vzal som si mal\u00e9 such\u00e9 kon\u00e1riky, o\u0161\u00fapal ich od k\u00f4ry a po d\u013a\u017eke rozrezal na polovicu. Niekedy to ide \u0165a\u017eko. Nechce sa im v\u017edy pravidelne rozdeli\u0165. Netreba z\u00fafa\u0165. Ak sa v\u00e1m nedar\u00ed roz\u0161tiepi\u0165 ho rovnomerne, z dvoch sa d\u00e1 spravi\u0165 jeden. Tak teda m\u00e1m dve polovice. Zarovn\u00e1m ich, aby do seba zapadli. Vybra\u0165 z nich du\u017einu je \u013eahk\u00e9 a na rad prich\u00e1dza na\u0161a \u201ezuho\u013enaten\u00e1\u201c tuha. Do krabi\u010dky som si dal viac kon\u00e1rikov r\u00f4znej hr\u00fabky a tak si vyber\u00e1m ten spr\u00e1vny. Na spojenie som pou\u017eil \u0161pag\u00e1t zo \u017eih\u013eavy. Na\u0161iel som u\u017e celkom vysok\u00fa, aj ke\u010f je e\u0161te len m\u00e1j. O\u0161\u00fapal stonku, z ktorej mi ostali vl\u00e1kna a z nich klasicky zaplietol \u0161pag\u00e1t. N\u00edm som potom zviazal v\u0161etko dokopy. Dal som tomu v\u00f4\u013eu a nestiahol to \u00faplne na pevno. Tuha sa r\u00fdchlo m\u00ed\u0148a a takto sa d\u00e1 v\u017edy povytiahnu\u0165. Ke\u010f s \u0148ou p\u00ed\u0161em, tak ju stla\u010d\u00edm prstami. Dr\u017e\u00ed pokope bez toho, aby sa \u010doko\u013evek h\u00fdbalo. Pekn\u00e9 na ceruzke je, \u017ee ka\u017ed\u00e1 s\u00fa\u010diastka sa d\u00e1 vymeni\u0165. A to je cel\u00e9.<\/p>\r\n\r\n\r\n
