Picture of How to make a mini forge out of an Altoids tin
In this instructable I have built a forge that really isn't to practical but if for some reason you need to forge yourself some paper clips this is the project for you.

Step 1: Materials

For this project you need the following:
-Altoids tin
-2" piece of brass tubing
-A tube of fireplace cement
-Perlite
-Rubber tubing

Tools
-Caulking gun
-Popsicle sticks (or something to spread the cement with)
-pencil torch (recommended)

Step 3: Adding the insulator

Grab your caulking gun and load in the fireplace cement. Then squirt it into a paper cup. Next, add in some perlite. keep doing this until you have the right consistency. You want it to be quite chunky for the first layer. If you want to make the final surface smoother, you can add fireplace cement to the gaps. Add this to your tin with the brass tube already inserted. Form the mixture with your popsicle stick. Try to completely cover the tube because otherwise it will melt. Remember to leave a hole so that the air can pass through. Use the location of the tube as your guide and slope the caulk/perlite mixture up to the edge of the tin as shown in the pictures. After that just let it dry and you are ready to start forging. When It dries you can duct tape the tubing on to the brass pipe.

thanks i need to heat up a penny to flatten it with a hammer but i didnt want to spend money on a torch
You better make sure the penny is made of copper! I think they quit using pure copper in them around 1973 (not sure). I was going to 'tin' a penny with some solder (just for yuks) and the instant I put the torch to it, it turned to liquid! It was then that I found out that pennies are made of babbitt (usually 95%-tin & 5%- copper).

But, in either case you won't need any heat to flatten a penny with a hammer; the hard part is holding it while you hit it hard!
I have a fully equipped Blacksmith Shop and I am hosting our Guild's February meeting and giving a demo. But I gotta tell ya, I will make one of these and am going to fire it up at the demo! LOL

Thanks!

i work with nails mainly and this looks like the thing for me. i hope i can build one soon because i don't want to blow a bunch of money of a propane torch that will be total overkill. great tutorial

you should post a couple of things that youve made with this forge

I have to admit, this is pretty freaking cool :) Now to go make one, and make a stick man out of paperclips.. or maybe a paperclip necklace selling buisness? ;)
Thank you! This is going to be incredibly useful. I had been trying to come up with a good way to heat spring steel then form my own custom tools for miniature sculpting and this is going to do the job perfectly.

it's a forge, right? where does the metal to be melted go?
steampirate (author)  jaencer3 years ago
you don't use a forge to melt metal. you use it to heat up metal. (it isn't particularly good at that either.) if you want to melt metal I suggest searching for a foundry or furnace instead.

where you get your pencil torch?
steampirate (author)  sharlston5 years ago
My torch is just something I got from harbor freight. I didn't expect it to last very long but it has served me very well. The only problem I have ever had with it is that the top burner assembly has fallen off. But it can easily be put back on and used afterwords.
how much and how long doesthe butane last?
steampirate (author)  sharlston5 years ago
The torch was about $5 and the butane lasts quite a long time considering it's size. Of course it does make a difference depending on how high the flame is.
what to use it for ?

Can this be used to melt aluminium into thick tubes??
steampirate (author)  mhkabir4 years ago
I cant imagine this is able to get that hot but it might be worth a try...
I tried: it works -- sort of.

The mold heats up and the tube is formed, but is rater brittle due to very ittle heat.

what is your air source? how did you rig a fan into a tube like that?
steampirate (author)  junits155 years ago
I have a forge blower that I made and it has variable settings so I just set it as low as possible. In regards to the connection, I used a piece of rubber and some duct tape.
oh, cool
very nice whats its higest temp?
I haven't measured but since it doesn't use as much charcoal as a regular forge it doesn't have as much thermal mass therefore lowering the temp.
