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.
Step 1: 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.
Step 2: Brackets
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.
Step 3: 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.
Step 4: 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.
