MANUFACTURING INSTRUCTIONS

These instructions are like a recipe for roasting chestnuts – the process is tried and true, but allows for some freedom in execution. Instead of watching TV series, you will here enjoy the most natural "program scheme" – the dance of flames and the crackling of firewood. For many, gazing into a fire is as meditative as staring at a television screen, except here, there's no risk of the remote control batteries running out. At Center Rog, we value creativity and manual skills, so building such a fire pit is an excellent mini-project for home. Upon completion, you will have enriched your knowledge of welding, measuring, and marking, and mastered skills like plasma cutting, grinding with an angle grinder, and assembling a relatively complex structure. During construction, a duty mentor will be available at every step to ensure the product is high-quality and safely made.

TOOLS AND EQUIPMENT

Measuring and Marking Tools (tape measure, square, protractor, marker or scribe)
Plasma cutter or angle grinder
Metalworking chisel
Angle grinder with cutting and grinding discs
Welding machine (MIG/MAG or TIG)
Magnetic squares and clamps for assembly
Drills, hole saw, and drill press
Protective equipment (safety glasses, gloves, FFP2 mask, hearing protection)

MATERIALS

Work Processes and Training:: Manufacturing the fire pit requires completed training for the multi-purpose station and training for MIG/MAG or TIG welding. This project is especially suitable for anyone wishing to gain additional practice welding thicker materials and performing longer welds. You can purchase the material (steel sheet) from the laboratory.

Mild Steel Sheet 4 mm – approx. 1 sheet 800 × 1000 mm
Small steel washers

MANUFACTURING PROCEDURE

Označevanje: Na pločevino natančno zarišite trapezne oblike, ki bodo tvorile piramido. Meritve preverite dvakrat. Za označevanje uporabite bel marker, voščenko ali risalno iglo. Dimenzije dobite v načrtu projekta.
Razrez pločevine: Pločevino položite na rešetko plazemskega rezalnika. Nastavite primeren električni tok plazme in razrežite kose. Kose izrežite nekoliko večje od končne mere, da lahko kasneje prilagodite dimenzije z brušenjem. Pred rezanjem vklopite odsesovalno napravo. Da bi dosegli maksimalno lep rez, uporabite ravnilo in magnete, ki ga bodo držali na mestu. Jeklen kotni profil se je izkazal kot odličen pripomoček za ravne reze. Vedno uporabljajte usnjene rokavice in ustrezno zaščito za oči!
Priprava robov: Odstranite žlindro s kovinarskim dletom, razigličite robove in preverite dimenzije. Odstopanja večja od 2–3 mm popravite z brušenjem. Kose sestavite "na suho" z magneti, da preverite prileganje.
Sestavljanje piramide Tri trapeze postavite z magneti in jih točkovno zavarite. Pustite majhen razmak med ploščami za boljši zvar. Nato vse stike dokončno zavarite.
Izdelava dna: Zvarjeno piramido postavite na pločevino in obrišite obliko. Izrežite kos, razigličite robove in izvrtajte nekaj lukenj za dovod zraka ter odtekanje vode. Nato ga privarite na spodnji rob piramide.
Brušenje: Površine zvarov in robove piramide pobrusite, da bodo pripravljeni za montažo nog.
Izdelava nog: Iz ostankov razreza trapezov izberite tri najlepše trikotne kose. Pobrusite in očistite jih žlindre.
Montaža nog: Noge točkovno privarite na dno piramide, preverite poravnavo in po potrebi popravite. Nato jih trdno zavarite. Na spodnjo stran nog privarite majhne podložke iz pločevine.
