A failed attempt at a small fire brick forge for my basement shop.

I need to get the right kind of brick, then away we go.

  • you dont NEED firebrick its just better than concrete, my first knives that i heat treated i use a plumbers torch and a broken piece of cinder block to set it on, the only thing i would change about your forge if it was me is make it smaller like you said and put the flame right on the steel angled down into a corner with the back of the steel against the angle, it might take awhile but it will work, and you have to keep working the steel back and forth to evenly heat it

  • good trying, play it safe!

  • .. um if you want it to get hotter you need to use something like concreat and to find a better producer of heat i think...

  • @Sare204 Try Canadian Tire. They have "Fire Bricks" listed on their website, which does the job.

  • Ok I Live in canada and i wanna make a Firebrick forge for smithing and such. Does anyone know of a source near Edmonton where i can get said firebrick fairly cheap? Thanks

  • The burner hole in the brick is acting as a venturi sucking in excess cold air so close it around the flame pipe and plug any leak there.

    The flame has all the air it needs from the venturi built into the torch and any air entering here just cools the chamber.

    Grout all the sides of the box except the door on the side.

    Leave the bottom of the door open a crack to vent the flue gas.

    Insulating firebrick will heat up much faster and use less fuel as well.

    Good luck!

  • I have built larger gas furnaces before, you may want to find a certain type of insul-wool (fiberglass) to line the inside. I haven't done this in years so i really don't remember :/

    For best results i would use natural gas. I will ask some folks that still deal in old forges

  • Nice work anyhow. You can use a flower pot as long as it's terra cotta. It don't get no cheaper. I've melted aluminum in one outside. They are cheaper than fire brick. You can use a bottom water dish for the top. They will last up to fifty or so heats.

  • For such a small area if you get rid of the 90 degree angles you may get it hot enough to get it to critical if you use map gas with those bricks. You can order refractory cement (Amazon) that is moldable and make your own brick. Also you need to make a bigger nozzle use one of the propane weed killers you can get at Lowes or the other place.. If you would like to contact me on my channel I can tell you how to make one for about what you have in that one there 8 or 10 bucks.

  • Hey keep trying, I think once you get the angle of the flame right you'll ber on track in no time.
