2 Brick Forge

I have been looking for a 2 brick forge design for a while and couldn't find any that met my needs. Most are 1 Brick Forges that are really too shallow for what I want to do.

I am working on longer pieces of 1/4 and 5/16th stock at about 5"-7" lengths.

This is my parts list:

  • 2 Fire Bricks 9"X4.5"X3"
  • 1" spade bit
  • 5/8th spade bit
  • 5/16th drill bit
  • Cold Chisel
  • 36" 5/16 - 18 threaded Rod cut into four even pieces 9" long
  • 16 5/16 - 18 nuts
  • 8 split washer
  • 4 one foot length 1"X1" steel angle stock
  • Power Drill

I decided that I needed an 8"x3"X3" chamber, so I marked the brick with a permanent marker.

Drilling

Using the 1" spade bit, I drilled out a honeycomb from the soft brick to a depth of about 1 1/2". I marked the spade bit to how deep I wanted it to go.

I took my time because of the soft nature of the Fire Brick, I didn't want to crack it.

Once I drilled out the chamber I used the 5/8ths bit to drill the hole to insert the burner.

Using the chisel as a scraper, I smoothed out the chamber floor and walls.

I drilled 2 holes on either end of one side of each angle stock. The stock should extend about 1 1/2 " past the brick.

I used a nut/split washer/nut method to measure out the leg height and locked the nuts in place on one end of each of the threaded rods. About an inch high.

Final Assembly

Sliding the rods threw the holes and bracing each side of the bricks, sandwiching them together, thread the remaining nuts in the same nut/split washer/nut assembly to secure the brackets around the bricks.

First Burn

Light and slide your propane burner into the hole on the side.

When I did the first burn, there was also a dust cloud from where I didn't get all the dust from the scraping out.

Also, I have read that a lot of these fire brick forges tend to crack during use. Most instructions that I read recommended just wiring the brick together. I thought that wouldn't look nice, which is why I went with the angle stock brace.
