- Tin snips
- Sharp chisel and hammer
- Corded or cordless drill or screwdriver
- Optional hacksaw
- Optional Dremel with fiberglass cutting wheel
- Large tin can. 10 inches wide, 11 inches tall (roughly)
- Smaller can about 8 inches wide. #10 food can type
- Computer style fan. (80 or 92 mm)
- 1/8" diameter metal tubing (flux brush, golf club tubing, small copper tubing from old fridge?)
- 2 1/2 inch deck or drywall screws. Any long screws will do.
The large tin can might be a popcorn or cookie tin. It can be a 5 gallon kerosene or hydraulic fluid container. It could be a metal paint pail with lid that seals. The container has to have a flat top and be completely intact.
The inner burn pot can be made from a #10 food can, or 2 stainless steam table pots (bain marie).
I use the inner pots from my other instructable in this one. Look there
for more info.
The single wall burn pot will work fine. It will radiate enough heat to melt your computer fan though.
The fan pictured below melted in this close configuration.
Cut the top hole in the outer can with a sharp chisel and hammer. Or use the chisel and hammer to get a hole started, then use tin snips to finish the top hole. Take your time and make the top hole PERFECT. The #10 food can/inner burn pot must fit TIGHT. This allows the gasifier to work best without needing weird exotic sealants you have no access to.
Next step will show how to make a basic duct to keep the fan a small distance away.
All this instructable shows is how to make a fan duct and gasifier if you have barely any tools and supplies.
