Here I´ll show you how to build a cheap desk with few materials and tools.
Step 1: Step 1. Gathering materials and tools
1 tubular chair, that can be obtained for cheap in a flea market or from used furniture store (just the frame will be needed) ~$10.
1 wooden board 60 cm x 80 cm or just a little bigger than the frame (~$4).
4 Phillips flat head screws for wood (30mm long max.) or similar to fix tubular frame to wooden board ~($1).
1/2 Liter of preferred color paint, or you can just leave it as it is, the wood smells always good.
2 Plastic belts (10 cm and 12cm)
Optional: 1 aluminum tubular profile 2.5 cm x 100 cm
1 aluminum rolling door profile (C shape) 4.5 cm x 100 cm
2 Phillips flat head screws for metal (30mm long max.)
1 aluminum bicycle bottle holder and screw, a plastic one can be used too, but for experience is kind of weak to hold a bottle of half liter of German beer, :-).
Electric screwdriver and bits, or manual.
Saw for aluminum
Driller and bits in case of need flat monitor stand
Step 3: Step 3. Fixing the wooden board
Place the verticals near to one longsides.
Fix to wooden board with screws using original holes from removed seat.
Stand up and paint.
And that´s it!!, now you have a nice table!
