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 2: Step 2. Disassembly of Chair
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!
If you want to improve your desk, you can follow the next steps.
Step 4: Step 4. Optional Accessories (bottle Holder)
If you want the flat monitor stand, then leave this step for later.
Step 5: Step 5. Optional Accessories (flat Monitor Stand)
The hole should be tight enough just to let the tube pass through with little effort, not loose.
Fix the tube to the "leg" with a plastic belt.
Step 6: Step 6. Fitting the Monitor Holders
Straight up the desk, take measures of your monitor hight and drill a pair of holes to screw tighly the profiles horizontally and parallel to each other to hold the monitor in between.
Slide your monitor through the profiles to test support, fix as needed to have your monitor in desired orientation and height.
Now, fix the bottle holder in your preferred side
Step 7: Step 7. Finishing
As you can see the monitor can be turned to any desired position having the tube as axis. As the chair´s tubular structure is made to support people (me= 100 kg) you can place a lot of your stuff over your new desk.
Fit the cables and hold them with velcro strips or plastic belts or pass the cables through the hole in the middle, in my case the VGA connector did not fit so I´ll do this later. Turn the monitor to see if the cables are long enough.
As the whole thing is also lightweigth, you can easily push/pull it once you are seated comfortably in your coach, having a tasty beer by your side.
NOTE: As you can see, there is no back support in case you push it hard, to move it away, just push the desk from the corner near you slightly pushing down, this will avoid to flip the table backwards. I'm working how to improve this. I hope you like it.
