DIY Soup Can Forge

ep_47.1Are you ready to take your prepping to the next level? Are you ready to take matters into your own hands? Are you disappointed with the quality of homemade survival gear and sick of struggling to find pieces that fit together? Here’s a nice DIY project that can empower you to shape metal according to your needs. No more having to settle for pieces that don’t fit. Less time wasted on searching and less money spent on purchasing metal parts. From now on you can use scrap metal to make what you need. You can actually create personalized blades, razors, tools and weapons with your own hands.

STEP 1: Materials you need


Standard Propane Torch – I used a Benzomatic TS8000 torch

Soup or Coffee Can – avoid galvanized metal

½” by 2” black iron pipe nipple

Plaster of Paris bag

Sand bag

Bolts and washers

Some metal L straps

A block of wood or something similar to act as support.

STEP 2: Attach the L straps to the block of wood



Make sure to measure the can and adjust the spacing between L straps accordingly. Use four bolts to make sure it is properly fixed. Place the straps as centered as possible to make sure it’s properly balanced.


STEP 3: Drill holes in the can


You want to mark the holes before drilling them. After drilling the mounting holes, drill another hole for the 1/2” by 2” black iron pipe nipple. It should be about 1” from the bottom of the can.

STEP 4: Mounting and filling the holes


Make sure you tighten the screws thoroughly. Use washers for better results.

Screw the iron nipple in as you can see in the picture. You shouldn’t need any tools for this.

STEP 5: Fire proofing mix


Make a 50/50 mix from Plaster of Paris and sand. The sand will add heat resistance to the plaster which would otherwise crack at high temperatures. Add a little water in the mix in order to bring it to a clay-like consistency.

STEP 6: Applying fire proofing clay

Once the mix is ready, proceed to fill in the can. You want to fill it up to 75 percent. Leave a layer of plaster mix of about 3/4” thick. You want it to be strong enough to hold heat while also giving you enough room to work with the metal. Make sure to scoop out any excess plaster mix and smooth out the core, using a spoon.


Make sure you clear the torch vent at the bottom. That is where the heat will come from after you have mounted the torch. Do this before the plaster is fully dried.

STEP 7: Clean the plaster smudges and fire it all up


Wipe excess plaster from the can or torch vent using a damp cloth. Place the torch in its socket and fire it up. You need to dry out the plaster mix first, but once you’re done with it, the forge is complete. A spiral head torch head would work best with this forge. Until the water is all dried out, the flame will be rather cold. However, it doesn’t take long before it’s burning at 2000 °F. That is hot enough for melting glass or metal.

Make sure to use safety goggles and gloves when operating the forge to avoid injury. The propane used to power it all up releases carbon monoxide, which is a serious health risk and can be deadly. Make sure you only use the forge in a well-ventilated room to avoid poisoning or other associated risks. This will allow you to work with small pieces of metal, making blades, arrowheads and other personalized survival gear that fits your plan. It’s cheap to make, easy to use and not too difficult to carry around.
