Well, that's exactly what I'd do.

Well, I'd go for about 1/2" thick, or maybe a little more. Maybe 3/4" or
1" on the bottom. It's hard to say without knowing much about the
specific refractory. I'd go thinner rather than thicker, as you can
easily add another layer of refractory. The thicker it is the better it
insulates, but also the longer it takes to heat up.

Well any adjustable regulator should work well enough. As long as it
worked I wouldn't worry about it. 

I have one that looks just like this one:
http://www.tejassmokers.com/images/COM230.jpg and I like it a lot. The
adjustment is smooth. I don't remember where I got it from, but I think
I paid something like $25--$35 for it. I also have a smaller adjustable
regulator from the local hardware store, and it works fine, it's just a
little harder to adjust to the pressure I want.

Remember, have fun, be safe, and let us know how your forge works out!

My friend's uncle is a refractory man, i don't know exactly what his
position is but he's some sort of contractor for refractory and fire
insulating work. That's insignificant though, the cool part is I get
free
refractories!!!

Here's What I Got:
1. 1" thick Kao-wool, durablanket or some brand of refractory blanket
2. ***Naphos-85   i have a couple gallons and with it Matt (refractory
hook-up) said "holds brick together up to .25"  thick" and "add water to
get
consistency of morter/slurry"
3. ***Ply Brico "trawelable* plastic .5" to 3" thick" and "fills cracks
&
voids etc. where there isn't a brick" *Real Sticky*
4. bag of AP Green Castable refractory
                         ***He also said that both the 'ply brico' and
'naphos' are 85% alumina where the standard is 50%

Here is what I want:
A forge... I cut the ends of a propane tank and burned the paint off for
a
forge shell. I'm not neccessarily set on this but it seems like the
right
size for my second forge, ( just today another friends dad gave me their
old
forge to use while I build my own). The hope is that with those
refractories
and one of mike porter's burners I'll have a forge pretty soon. I've
already
forked out the big bucks and bought most of the parts for the .5 & .75"
burner's in his book.

now for the actual questions:
1. I've read about Jerry using a couple layers of Kaowool protected by
refractory cement and rather liked the idea, but would like to hear
other suggestions considering the materials I have.

2. If I decide to go with the two layers of kao-wool how thick should I
lay
on the refrectory cement and which one should I use? should i do like
.75"
on the top and sides and 1.5 or so inches on the bottom?

3. Is there a website or anywhere in particular where I should buy a
regulator, or will most places pretty much be the same: central welding
supply, hardware store, etc.

Any other suggestions?

Thanks always for your advice,
Luke
