2 x broken metal stools from your local school district
1 x replacement propane burner (cast iron, available at your local homebrew supply store)
1 x brass orifice
1 x combo regulator, propane hose, needle valve assembly
Step 1: Cut and bend pieces from the stool, and grind down burrs/sharp bits
Make sure you switch from a cutting wheel to a flap disc to grind down sharp bits from the old welds. Secure with jigs/clamps so that you don't have an accident. Safety first~!
Step 2: Cut legs to length
Step 3: Coping/saddle joint
