[TheForge] Forge Lining

[Mike Porter]

Luke,
This is a lot of territory to cover. I'm sure the materials you have
available are a great advantage (insert jealous gnashing of teeth here).
However, the design process should begin at the end; with what you wish to
use the forge to accomplish, not just what materials you have available. It
might be that you will do best with a box forge, or a configurable pile
forge, or even a clamshell forge, rather than a tube forge. What is it that
you wish to do with the forge? What do you want to make?

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
