Step 1: Find Some Bottle
Step 3: Any Old Iron
Step 4: Mock It Up
I marked out where the hinge would go, drilled and tapped with a 4mm tap and attached the hinge using 4x10mm machine screws. I find it easier drilling and tapping and attaching the hinge while the bottle is still intact.
All the holes and details in the bottle we're made using a 4" angle grinder with cutting discs and a 10mm drill bit.
I drilled several holes around the bottom of the bottle so air will circulate and help the fire to burn.
