I wanted to forge a knife.
But my old forge got scrapped. (Not that it was anything special. It was junk. Like most of my forges.)
I needed a forge. But I felt lazy.
So I grabbed a sink. And forged a knife.
WARNING: This is the lamest Instructable I've ever made.
Step 1: Video
Step 2: Cinderblock Base
You need some sort of platform or base to set up the sink (ahem; forge) on. It must be solid enough to support the weight, and have a gap underneath for the drain pipe to go down, so you can attach an air supply. It should also be heat resistant, as forges tend to get hot.
I had a few cinderblocks sitting around, and they seemed like the logical choice.
Step 3: Duct Tape. Lots of Duct Tape.
Duct tape is just the bestest stuf in the wurld.
^^ misspelled on purpoise
I know you think I'm nuts, but hey, it works. No point in wasting time and money buying pipe fittings. This is a quick-n-dirty forge.
I connected a metal pipe with a 90 degree angle to the drain pipe on the sink. I'll connect my air source to that.
Step 4: Hair Dryer Hacking......
There are a few choices when it comes to an air supply.
Hairdryer, leaf blower, heat gun, air mattress inflator thingy, etc. I went with a hairdryer. Mainly cause it was the only one I had.
Yeah, I just duct taped it to the end of the pipe. It works. You can be fancy if you want to be.
Step 5: Bent Wire Thingie
To keep the charcoal from falling into the drain, I crunched up a piece of wire fencing and stuffed that in the hole. That will keep any large pieces from falling down, and the smaller bits and dust should be kept out by the air blowing through the pipe.
Step 6: Fire Up the Sink!!!!
Wow, done already.
The forge actually worked very well. I was able to get up to forge welding temp easily and the sink help up to the heat just dandy. For forging out small stuff like knives, this is a very viable option for the monetarily challenged.
Or for those who just want to throw a forge together and start bladesmithing.
See ya' in the next (hopefully more interesting and better documented) project!
