Feeling a little black-smithy? Ever wanted to hammer some red-hot steel into a new shape? Turns out, it’s well within your reach!
The problem is, fire bricks are kind of fragile. In order to drill into it without cracking the brick [Mike] advises us to clamp it in a wooden jig to help support it. Slowly drill a long hole lengthwise in it, slightly oblong to allow for your work piece to go inside. Flip the brick sideways, and add a second perpendicular hole in order to insert your gas torch of choice.
Now before you go heating it up, it is wise to reinforce the brick by wrapping some wire around it to prevent it from falling apart when it inevitably cracks due to temperature changes. A more permanent solution is to encase the entire brick in concrete to make it more durable, which [Mike] plans on doing next time.
He learned how to do this at his local maker’s guild, Prototek OKC – the Oklahoma City Makerspace community. Check out his first attempts at forging!
Now all you need is an anvil…
