Tools you will need:
- 1. Hacksaw (or at least the blade)
- 2. Cutting pliers
- 3. Drill and bit
- 4. Utility knife
- 5. File (or sandpaper)
- 6. Ruler
Of course these are not mandatory, you are welcomed to improvise, but please wear safety gear and respect work security guidelines (or suffer the consequences of your foolish actions, I don't care).
Basically you need 2 pieces of pipe, one must fit in the other, I used 18mm (3/4 Inch) and 15mm (5/8 Inch) copper tube; any metal should do, but I used copper because: its relatively lightweight, doesn't bend much when exposed to fire, it has thin walls and most importantly I had them lying around the house (leftovers from the heating system) so they were free.
2 copper tube caps that fit the larger diameter pipe (also lying around and also free).
Handful of approx. 2mm diameter bicycle spokes (1/16 inch), I can't give you an exact number, you'll see why in a bit. Make sure that you use stainless steel spokes, you're going to eat off of them.
Pro Tip: If you have a bicycle repair shop nearby, you should ask them for broken spokes, you may get them for free (I hacked my old bike tire to death for this).
This is pretty simple since you'll need to cut everything to the same size (you will get a rectangular grill).
Pro Tip: The bigger you make your grill the more spokes you'll need, make sure that the number of spokes you intend to use all fit inside the smaller diameter tube.
I made mine 20 cm wide (7.87401575 inches, just make it 8) since I found that about 25 2.2mm spokes fit inside the 15mm diameter tube.
