This is just a simple step-by-step instructable with some pictures and the file i made in google sketchup.

I hope you like it.
Step 1: You Will Need:
4 nuts and bolts
2 metal or wooden slabs
1 grill plate
Step 2: Angle Grinding
Then cut two 2cm slits, either side of the gas bottle, as shown in picture. Or if your making just a bbq, you can cut the side off the gas bottle for more room.
Sand the sharp edges
Step 3: Slabs and Bolts
drill a bigger hole in the slab of wood or metal only the thickness of the bolt head.
also drill two holes the same size in the middle of each slab.
then arrange as shown in the picture and tighten the nut and bolt so that the bolt head is in the bigger hole and not sticking out the bottom.
The red is simply there to show the hole.
Step 4: Finishing Touches
Now all you need to do is light the fire and place the grill in the slit.
