Spajanje zakivanjem (postupak)

Drvo se najčešće spaja zakivanjem. Spojene delove možemo kasnije rastaviti ne oštećujući drvo. Ako osim zakivanja upotrebimo i lepak, spojevi će biti naročito trajni i izdržljivi.

1. Dubina zabijanja vrlo je važna za izdržljivost pribijenog drvenog spoja.
2. Ovako razmešenim ekserima sprečen je raskol letvica. Ekseri ne bi smeli biti predebeli.
3. Puno drvo neće se raskovati za vreme zabijanja ako sabijemo vrh eksera.
4. Male eksere možemo pridržavati kartonskom trakom, pa se nećemo povrediti ni izgubiti ekser.
5. Spoj će biti čvršći, ako eksere zabijamo koso. Na taj se način zabijaju podne daske.
6. Nevidljivo zabijanje. Dletom podignemo iver, zabijemo ekser i zatim iver prilepimo.
7. Unakrsno zabijanje. Na taj način možemo zaštiti potpornije ili grede od isklizavanja sa strane. Glave eksera su ovde ukucane.
8. Glave eksera možemo ukucati u drvo i pomoću drugog eksera, koji se posle toga više ne može upotrebiti.
9. Za "pravo" upuštanje potreban je probojac (levo). Rupu koja nastane ispuniti kitom za drvo pre no što obradimo gornji deo. Ako vrh eksera viri, može se naknadno sabiti. Na suprotnoj strani podupire se velikim kleštima ili drugim čekićem. U protivnom će ekser uvek ispadati.
10. Eksere koji su "probili" moramo uvek saviti. Preko stare turpije ponovo ćemo ih zabiti u drvo.

Slike se nalaze u prilogu.

Spajanje drveta lepljenjem (postupak)

Spojevi lepljenjem stolarskim lepkom izdržljiviji su i od samog drveta, pod uslovom da su valjano napravljeni. Važno je da ih dobro pritisnemo. Slike će vas uputiti kako da uradite trajne spojeve.

1. Dobra priprema i prikladan alat važni su preduslovi uspešnog lepljenja.
2. Pre lepljenja treba ukloniti naslage boje. Kada lepimo obojeno drvo, moramo očistiti kontaktne površine pre nego što ih namažemo lepkom.
3. Ako se radi o manjim površinama, lepak se na njih maže četkicom. Velike površine treba jednolično premazati nazubljenom lopaticom.
4. Višak lepka istećiće iz fuga, ako ih pritisnemo, pa ga treba odmah i odstraniti. Ukoliko nameravamo drvo bajcovati, lepak se mora najpre osušiti.
5. Drvene stezaljke poravnati sa pločom da ne ostavljaju tragove. U klasične stezaljke mogu se staviti otpadni komadići drveta.
6. Na taj način izbeći će se ostavljanje tragova na drvetu.
7. Obloge za pojačanje rubova mogu se pritisnuti i stezaljakama za rezbarsku testeru. Razmaci među stezaljkama moraju biti kratki.
8. Lepljenjem uglova steže se kvačicama koje se postavljaju specijalnim kleštima
9. Ploča od dasaka lepi se ovako: na dve letve pribiju se daščice, a zatim se između njih i dasaka zabiju klinovi.
10. Lepljeni ugaoni spojevi stežu se uvrnutom vrpcom. Daščica za učvršćivanje uglova sprečiće urezivanje vrpce u drvo.

Spajanje drveta čepovima sa klinovima

Klinovima osigurani spojevi na čep poznati su još od davnina. I danas se smatraju pouzdanim. Ako su izvedeni prema pravilima zanata, izgledaju veoma lepo. Kućni maistor može na njima dokazati svoju spretnost.

1. Čep kroz koji je provučen klin, smatra se vrlo dekorativnim spojem. I rupa u čepu i klin skošeni su pod uglom od oko 10ş i tačno međusobno prilagođeni.

2. Ova vrsta spoja naročito je prikladna za nogare stola i za male komade pokućstva. Rupa za klin buši se uvek popreko na tok šare drveta.

3. Ova vrsta klinom učvršćenog spoja upotrebljava se uglavnom za vratnice. Široka površina čepa tačno prijanja u rupu i sprečava iskliznuće sa strane.

4. Površine klinova samo su lagano iskošene. Pre zabijanja treba ih tanko premazati lepkom. Oba se klina podjednako zabiju i odrežu se komadići koji vire.

5. Čep sa četiri klina prikladan je prvenstveno za sto čiji nogari imaju kružnu stopu. Najpre treba napraviti i prilagoditi preklop, a zatim izbuštit rupu za čep.

6. Ukršteni urezi testerom služe ovde kao prorezi za prihvatanje klinova.Klinovi su ovde gotovo sasvim pljosnati.

7. Ovaj se spoj ne "klima" stabilan je i ako se ispravno napravi, povezuje ukrštenu stopu s potpornjem i takođe njene delove međusobno. Svi delovi se lepe.
