Hi guys, I'm being a bit lazy here.  I don't want to spend a month 
wandering around the internet buzz to analyze a bunch of opinions by 
people who probably have never done the work.

So, here's what I'm looking for.  I bought Larry Williams' tape on 
making hollows and rounds and he talks about heat treating irons using a 
torch on a propane tank along with a couple fire bricks to contain the 
heat.  Then he talks a little about how to identify the proper 
temperature.  So, I'd like some pointers from folks who have actually 
done this; I know you are out there.

I'm looking at a propane torch like this from HD:

Propane-Torch-Kit-KH825-01/100341111
      500K BTU ought to do it, right?

To determine the right temperature, I've heard of going by color, I've 
heard of using a magnet (like I'm gonna stick a magnet to a chunk of 
metal at a 1000 degrees) Larry Williams talks about 'watching the metal 
sweat'.  So, can someone point me to something that works?

Quenching, I hear abut vegetable oil, peanut oil (smells better, they 
say) and I guess old motor oil would be ver botem, too flammable, right?

So, any one doing this at home?  Any videos out there on how I want to 
approach this?  Any help much appreciated.

Thanks,
