As mentioned in my last instructable Fire extinguishers are amazing and mostly free. What we will be building today is a home made forge capable of melting stainless and we tried glass but it just went mushy.
Gas tank empty (free)
Gas tank full (have)
Fire extinguishers (free)
Step 1: Empty gas tank Clean Clean Clean
Then put a regulator on hung it upside down and turned it on.
Drill small hole in top BE CAREFULL
Drill another hole in bottom
The tank will be quite full with gunk that smells really bad.
YOU MUST CLEAN BEFORE CUTTING.
To clean it out we then made these holes much bigger then put lots of boiling soapy water washing out threw the gas tank.
Step 2: Building forge
This is now our main holder for the forge.
Step 3: Setting up the holder
We packed the sides with engineer bricks we are using bottom of fire extinguisher for our melting pot.
Step 4: Flare
The theory is that when you pump gas throw the small pipe and then down into much smaller hole you are injecting quite a large amount of gas to small hole. The hole is back of tube pulls air in mixing with gas.
