The risk assessment might not always be low on this one haha. I think I'm understanding the potential dangers of a gasoline powered forge compared to something like propane, waste oils, or diesel. Because gasoline has such a low flash point, it is a perfect source for a fuel air (thermobaric?) explosion. It can build up in the air inside the forge, start to vaporize and collect, then explode when I light it. Waste oils and diesel have a significantly higher flash points, so the likelihood of a fuel air explosion is reduced. It can still accumulate in the forge, but it will only light in vapor form at temperatures greater than ~520 F. I'm essentially playing with fire if I use gasoline. Because it is so easy to light at ambient temperatures, all it takes is one mistake and BOOM. While diesel and other waste oils require significantly higher temperatures in vapor form to combust. Hell some might even start to boil before they combust. If I'm not missing the mark too much here...I think I'll convert my furnace and forge to diesel and use a propane pre-heater. I really appreciate all of your feedback!

I think it roughly 1 gallon every ~3 hours at full blast. It takes some time to heat up though as it needs to be babied before I can increase the pressure. I was going to Home Depot (and stores like that) to have it exchanged. At like $30 a refill, I was thinking there had to be a better way. Is the Fuel Air explosion not a concern waste oil burners too?

Good Afternoon everyone, I'm a long time lurker of these forums, but I've never posted as most of what I was going to ask was accessible via the search bar. This is the one exception...I think. Question: What are your opinions of gasoline powered forges? I ask because I'd like to take my current gasoline furnace setup and reconfigure it to power a forge to start learning basic blacksmithing. ------------------------------------- My furnace at home gets to ~ 2500 degrees in ~30 minutes and is made from a full sized beer keg. It runs on compressed air and gasoline (the stuff in a car). It uses a Delavan siphon nozzle to generate and maintain the Air/Fuel Mixture (See attached picture). Aside from operator error and some design flaws, I've had no dangerous situations with it...yet. I ask specifically about gasoline because I've read about a lot of waste oils such as cooking oil, motor oil, and diesel. However, no one specifically mentions gasoline. I wound up using gasoline because I got tired of swapping propane tanks in my area. It seems to always be a problem in good ole Augusta, GA. Oh, yes I have the fully litany of safety gear and equipment such as: Respirator, Face shield, Flame retardant clothing, etc. I'd love to hear your opinions on the matter before I start hacking away at a forge using the same technique.
