How To Build A Forge At Home

Wouldn’t you like to forge glass or metal devices in case of an emergency or survival situation?  Wouldn’t you like to forge you own knives or tools from scratch?  Or maybe you want to impress your lady that you not only know how to forge metal; but you also know how to build your own forge from scratch?

Making or shaping your own metal objects by heating it in a fire and then beating and hammering is the true essence of what it means to be a man.

100+ years ago, many of our ancestors forged their own metal.  And about 25% of them had the occupation as a blacksmith.   It is a ‘skill’ & ‘trade’ that we feel should still be learned by any one looking to be more prepared or live more self-sufficiently.  Plus, it’s a lot of fun!

On this page, we will teach you how to build your own forge at home. We provide you step-by-step video and image instructions; and provide you with a list of all the tools and materials you will need.

Build A Forge At Home MaterialsForge Tools And Materials Needed

Materials

– Large Soup Can
– Two L-brackets w/ Bolts & Washers
1/2-Inch by 2-Inch Black Iron Pipe Nipple
– 50/50 mix of Plaster of Paris / Sand
– Block of Wood
– Water

Tools

– Standard Propane Torch
Drill
– 2 Wrenches, Screwdriver, & Spoon
– Sharpie Marker
– Wet Rag and Large Sandwich Bags
– Safety Goggles

 

attach the l-bracketsStep #1 – Attach The L-Brackets

Attach the 2 L-brackets to the bottom block of wood serving as the base.

Space the L-brackets to align with the front and back portion of the can.  And then proceed to screw the brackets into the wooden block.

Hold the can up to the L-brackets, and with your sharpie marker, make markings through the top holes of the L-brackets.  This is where we will drill holes in the next step.

Drill and fasten can

Step #2 – Drill and Fasten Can

Drill in holes where the markings were made in the previous step.

The soup can is now ready to be attached to the L-brackets.  Grab your 2 wrenches and your bolts and washers.

Make sure that everything is tightened securely to avoid any mishaps.

Drill In Iron Pipe NippleStep #3 – Drill In Iron Pipe Nipple

Now we will drill in a larger hole to fit a 1/2-Inch by 2-Inch Black Iron Pipe Nipple.  This is where the torch will be inserted.

Drill the hole opposite the L-bracket mounting holes, and at a slight downward angle as seen in fig. #2.  And positioned about an inch from the bottom portion of the can as seen in fig. #3.

Then screw in the pipe nipple into the hole as seen in fig. #4.

The can is now ready to receive a fireproof lining which we will describe in the next step.

Prep The Fireproof LiningStep #4 – Prep The Fireproof Lining

The fireproof material will consist of a 50/50 mix of Plaster of Paris and Sand.  Any type of sand will do.  The sand will add heat resistance to the plaster, which would otherwise crack at high temperatures.

Mix these 2 materials in the large sandwich bags as seen in Fig #2.  Add in water to the mixtures until it reaches a soft clay-like consistency as seen in fig. # 3 & 4.

Immediately proceed to the next step to avoid the plaster mix from hardening too quickly.

Shape The Fireproof Lining

Step #5 – Shape The Fireproof Lining

Simply start shoving in the plaster mixture into the can opening until it reaches about 75% capacity.  Then core out the center until you reach the bottom to where the torch will come through the pipe nipple.

Be sure to leave about 3/4 of an inch of the fire-proofing material coating the can’s wall.  Your spoon will work great for soothing out the core.  make sure to widen it slightly toward the bottom.  This will allow the heat to stay contained for longer before exiting it’s narrower mouth.

Now take your sharpie marker and poke through the pipe nipple to remove any plaster that may have clogged the opening.  You can also use your screwdriver to smooth it out.  Use your wet rag to clean up the can’s surface of any plaster that may have dirtied it up in the process.

Get Ready To Start ForgingStep #6 – Almost Ready To Start Forging

We are almost ready to start forging.  For safety precautions put on some goggles and make sure you are in a well ventilated area for any carbon dioxide risks.

A spiral-flame torch head works best for this forge.  Insert the tip of the torch into the iron pipe until secured. Warning:  Some torches have air holes close to the tip, so make sure they are not covered.  If the air holes are covered the torch will produce carbon monoxide which can be dangerous. Do not cover the air holes. Make sure they are outside of the forge.

You can now turn on the torch.  It may take a while for the flame to extract all the water from the plaster walls; so the first burn will be rather cold.  But give it a while, and it should be cooking at 2000+ degrees fahrenheit; which should be hot enough for fabricating, shaping, and forging steel or glass.
