So why not use an instant BBQ? Well these are designed to be disposed of, after use. However, I can guarantee that only a few people take apart the BBQ to remove the coals and then rinse out the tray as recommended on the packaging. This is a waste of resources and not only that, it is more costly than buying the fuel separately for a reusable BBQ.
Step 1: Materials: Junk
- A Colander, this is like a sieve but is made from a thick heavy metal and has fewer larger holes in. (free)
- An old ATX PSU with a built in fan grill, it doesn't need to be a working PSU as this won't matter.
- Any two miscellaneous nuts and bolts that will fit.
- Washers that fit the bolts
- stainless steel wire for the grill
- A round microwave rack from a combi microwave / grill
- Philips Screwdriver
Step 2: The Base:
To make the base and old ATX PSU is used:
- Remove all four screws around the case. There may be more on your case.
- Lift off the case and keep the screws in a pot for later.
- Gentally follow the wires from the fan and unplug / cut away from the main board.
- Remove the futher four screws holding the fan in place and put the fan away for other projects
- Remove the screws holding the circuit board in place and put to one side.
- Drill the holes in the correct place by lining up the colander if required.
Step 3: Fire Chamber:
- Push the two bolts through the corresponding holes in the colander and then through the PSU.
- If the bolts don't fit, either use smaller ones or drill out the holes to make them bigger.
- Put on some washers if more height is required.
- Tighten down the nuts to secure the two.
Step 4: Grill:
- Squeeze the leg of the grate at the top and bend the leg out and up holding the pliers in the same place and position, the whole time.
- Repeat for he other two legs.
- Flip the grate and place in the colander and bend the legs to fit.
Step 5: Optional:
- Get the other part of the ATX PSU case
- Screw it back together whilst attached to the colander
- Using stainless steel wire, wrap between the rods of the grill. This will fill out the grill and will stop small food from falling through.
- Repeat until all substantial holes are reduced.
- Mount a small 60mm or a 80 mm fan back into the side of the PSU
- Screw the fan in place
- Hook up to a 12V battery or 12v DC power adapter
