We have got an anvil, hammers, charcoal, steel to hit, tongs to hold it
with, and a couple of books to boot.
We are are working on the forge. We are myself and my seven and 12 year old
kids. I was sold a nice rivet forge blower from a nice guy out East ( I
think his name is Tom if you're out there thanks). Now we need to make the
forge. 'Got an old brake drum but is is very thin on the bottom and not
really compatible with the blower. I would like to make something smallish
aout of 3/16 or 1/4" plate. Does 18" round or square sound about right for
that blower?
Square allows easy angle iron sides. Round looks cool and would get 14 gage
around the sides. I'll hang the blower off the bottom and I have a motor
with pully and belt from an old grinder that matches.
Thanks, Jim

For a coal forge you want a smaller box that is lower than the rest of the table.
This box is called a firepot.
The firepots I have made from 1/4" steel plate were square tapered boxes.
The size that might works for you is 10" x 10" on the top edge, and 8" x 8" on the bottom, and is "
deep.
The bottom of the box has a hole about 2" diamter in the middle.
You go to your local plumbing shop and buy some 1-1/2" pipe fittings to make up a 12" piece that
goes from the botttom of the box straight down.
It has a flange on top that bolts to the bottom of the firepot.
6" down there is a "T" fitting that points to the side.
The pipe continues down for 6" and has a little sheetmetal hatch that covers the bottom and has a
counterweight to keep it against the bootom of the pipe, but by lifting a handle the hatch can be
opened.
This is you ashdump.

From the side of the "T" fitting run a pipe horizontally for about 12" and there you will mount your
blower.
In the bottom of the firepot you want a loose piece of 1/2" steel 8" x 8" that just fits into the
bottom of the pot.
In the middle of this 1/2" plate you drill a pattern of 3/8" holes like a 4 leaf clover.
This is your tuyere, where the air blast comes up through the coal.
You can use a brake drum for the firepot.
The firepot should be in the middle of a larger table top where you have enough space to pile some
coal around the fire.

If this makes no sense try checking out the Centaur Forge website and look at some commercially
available forges.

I have some rough instructions and a drawing on my website at:

http://www.geocities.com/Heartland/Lake/7316/brake.html

The brakedrum is used to make a firepot that sits in a metal table
(the hearth). If the brakedrum seems to be too thin, you can line it
with clay or dirt that has a high clay content. The hearth/table
can also bwe clay lined, so you don't absolutely have to use thick
metal. The size of the hearth depends on what you plan to use it
for, and how much space you have to work in (weight becomes an issue
if you plan on moving the forge).

If you are using galvanized pipe fittings and need to torch or weld
them, the hardware store or a welding supply store should have the
acid necessary to remove the galvanized coating.

Ernie and Pete-
Thanks for the tips. I got some 3/16 plate from my local junk man ( an old
hatch cover from something) about 18 x 24. I am going to use that for the
table. I have a small piece of 5/16 plate that I will cut up into the
pieces to make the firepot. The blower has the T-shape built into it. The
fitting for the ash gate it gone. I think I'll weld some flat bar onto the
bottom of the table and connect a thin plate to two springs to the flat bar
to cover the bottom of the blower for an ash gate.

About the homemade tuyere (is it said tweer?) iron, thick is better I take
it. About the cloverleaf hole pattern, are you looking to get as many holes
in it as you area of your blower pipe or are you looking for more or less
than that.

Jim,

It's generally a good idea to put as many holes as the tuyere size will
allow. However, be sure to leave enough material between holes to
prevent rapid burnout. My grate of 1/4" plate is still going strong
after three years.

If you can find a chunk of cast iron plate, that is even better for a tuyere (yes it's pronounced
"tweer", silly french).
I find that you should try to have as many holes as possible, but try to leave webs between them
that are thick enough that they won't burn out.

If you get good coal, the clinker and slag will form a donut ring in the bottom of the firepot that
you can remove easily once cooled.

Try to make the handle on the ashdump easily reached .

Do you need a coal source?
If so , what part of the world are you in?

I am in SE Minnesota about an hour away from Rochester and Minneapolis/St.
Paul.
I was wondering if I could use charcoal resulting from a wood fire. Burn
the wood in the stove to heat the shop, then when it is time, shovel the
"charcoaled" embers out of the stove into the forge. Not 100% perfect but
at least the heat will be there in the shop as we sit and figure out what to
do next.

Source for coal? I am also in the northland. We have lignite coal in this area
(eastern North Dakota[Grand Forks]). Any suggestions on how to get better
quality coal up here? Thanks.

Kurt.

I think it is.

I just wish I could get better feedback on more suppliers.
