PORTABLE FORGE

OPERATING AND REFRACTORY LINING INSTRUCTIONS

WARNING

FOR YOUR SAFETY

THESE INSTRUCTIONS ARE INTENDED

AS AN AID TO AN INDIVIDUAL FAMILIAR

WITH THE OPERATION OF A GAS

FORGE. IF YOU HAVE NEVER USED A

GAS FORGE, SEEK HELP IN LEARNING

GENERAL OPERATING AND SAFETY

PROCEDURES FIRST. READ THESE

INSTRUCTIONS THOROUGHLY BEFORE

ATTEMPTING ASSEMBLY, INSTALLATION

AND USE OF YOUR FORGE. FAILURE

TO DO SO MAY RESULT IN PERSONAL

INJURY.

-Do not store gasoline or other flammable

vapors or liquids, or other combustible materi-

als in the vicinity of your forge.

-Keep LP gas tanks at least four feet away

from the forge.

-Keep hoses, valves and gauges away from

heat generated by the forge or forge doors.

-Use only in a well ventilated area.

-If you smell gas: shut down the forge imme-

diately and check for leaks. Do not rely on

smell alone; use a fuel gas and CO detector

to find leaks.

The user of this forge and burner assumes all liability and responsibility for proper installation, maintenance and

use of this forge and burner, and the maker is in no way responsible or liable for the failure of the user to observe all

safety precautions in the use of this product.

ASSEMBLY

There are four parts to

this forge: 1. Case, 2.

Face Plate, 3. Door,

and 4. Burner

Assembly. To assem-

ble, install the ceramic

liner as shown on p.

3. Bolt the two face

plates to the case

using the supplied ¼-

CERAMIC LINER

Your forge is supplied with a ceramic wool liner, hard ceramic hearth floor block and cast-

in-place ceramic doors. The wool liner is already cut to size. To install: 1. Seperate the

wool into two strips from the end to the burner tube opening. 2. Slip the wool over the

burner tube and wrap it around the interior of the forge housing, tucking one layer under

the other at the end. 3. Seperate additional ½” thick strips, roll them up and insert into the

upper corners of the case. Place the hearth floor block in the bottom of the case, between

the ends of the wool liner. After bolting the case together line up the holes in the face

plate and hearth block and insert the set screws to hold the block in place. It is strongly

recommended that you paint your forge with a high temperature paint such as “Rust-

Oleum High Heat” paint (good to 1200°F).

SETUP

Your forge can be mounted on a steel bench or table, pedestal, stand or swinging arm.

Allow plenty of space behind and around the forge for handling stock. Hardware needed

includes a regulator, (for example a Fisher type 67, available at most propane distribu-

tors), ball valve and hose. Locate the LP tank (40-100 lb portable tank recommend) away

from the forge with the regulator mounted to it. Attach the ball valve to the regulator and

connect to the forge using a hose with ¼” NPT fittings.

OPERATION

WARNING: Never rapidly heat a forge with newly cast refractory. Before you can

use your forge you must first drive moisture out of the cast refractory by heating slowly.

WARNING: Never leave the forge unattended while it is running.

To start your forge: 1.close the ball valve and open the LP tank valve all the way. 2. Set

the pressure at the regulator to 25lbs. and make sure the burner draft control is at least

half open. 3. Stand away from the hearth opening, and place a small wad of burning

newspaper in the forge and slowly begin opening the ball valve. 4. Once the forge starts,

open the ball valve all the way. After about 10 minutes the forge will reach forging temper-

ature and the draft control can be adjusted to achieve a neutral flame (close down, then

open to a point where a neutral flame is achieved). The forge operates at a gas pressure

between 15 and 35 lbs. Forging range is between 20-25 lbs and welding range is

between 25-30 lbs. Operating pressures below 15 lbs will cause the burner to sputter,

indicating that it is no longer drawing air. Choose a door with the smallest opening need-

ed to do the work at hand. Do not close off the entire heating chamber with two solid

doors. To shut down, close the ball valve, then the LP tank valve. Note: This forge is

deigned to work up to 2000 ft. above sea level. The burner jet is interchangeable and can

be replaced to work at higher elevations.
