I kind of fell off the map/got busy...How is it going ? I just resolved to use peanut oil but 4 bucks is tempting. As long as I don't have discharge a 35 dollar fire extinguisher.

I fell off the face of the earth too. However I only need to get air flow under control before I'm ready to heat treat. I've had a few "flare ups" in the past but have never had something uncontrolled that required emergency action. Although having precautions near by is always a good idea. It's our anniversary this weekend, so not much more will get done for a few days.

Flareups are pretty harmless. The major thing is to keep your face away from the quench (which is always a good idea) and don't put combustible stuff next to the quench. I do all forging and quenching in my smithy outside. Originally Posted by 10Pups

Putting the whole blade under the surface oil helps with flare ups also. When you leave some red hot metal above the surface it tendsto flare up a little bit there.

That is absolutely true. No oxygen -> no flare. The mistake people make is to be hesitant during quench. It can mess up the quench, and cause flareup. Originally Posted by spazola

I won't be messing around. As I understand it the faster it goes in the better. I have a fire extinguisher handy when I light a cigarette :<0)
"not much more will get done" ?? It's your anniversary , you better get something done :<0) You got shopping to do, reservations to make.Good judgment comes from experience, and experience....well that comes from poor judgment.

A couple of things about extinguising fires in a workshop.
After a couple of quenchings, esp with a small container, the oil is very, very hot. Whatever happens, don't spray water in the quench tank. Bad things will happen.
Think water in a deep fryer. The second thing you need to know is that if you extinguish with powder, the powder gets everywhere. Literally. It is also destructive. A fireman once told me that a powder extinguisher discharged inside a house will yield approximately 20000$ in damage.
Knowing that, it pays to put the quench setup and your fire somewhere that is more or less safe in case something goes wrong. And put some thought into how you might extinguish a fire. Look I don't want to scare you. I've never had anything burn accidentally and I've made a lot of fires in my forge and did a lot of quenching. However, unnecessarily using a powder extinguisher will probably end with your wife being so made at you that you won't be making any fire for a loooooong time

Well, I got the "forge" lined with fire bricks. It took a trip to my Dad's house. We had dig though all my old stuff from when I was forging knives in his back yard as a kid. Also, I was able to get some airflow control. I realized that my shop vac is just a series DC motor (otherwise known as an universal motor as it can run on AC or DC). The way to control a DC series motor is to vary the voltage. So a simple light dimmer is all that's needed. Just plug in the forge, plug the shop vac into the outlet on the forge and turn the knob.

Brilliant plan with the light dimmer switch!
On a side note, I have a degree in Fire Science. Been doing Fire Fighting for the past decade. Specializing in extinguishing flammable/combustible liquids (jet fuel mostly) and hazardous materials. If any of you guys that forge want any type of safety or extinguishing advice, please feel free to get in touch with me.
