For this simple forge you will need several usual items:

A hair dryer (In the final version I used 2000W hair dryer FS-09 with the cold air switch)

An iron pipe (non galvanized) I used about 1 m long and about 1.5 cm wide pipe

A piece of hose (wide enough to fit the pipe, at least approximately) I used about a 50 cm long hose. It helps you -manipulate the forge because it is flexible, but probably you could connect the hairdryer directly to the pipe.

A duck tape (Optional)

A plastic bottle (I used 0.5 and 1.5 plastic bottles)

Step 1: Cutting the Pipe

Cut the pipe as on the photos.It would probably be easier with the proper tool.

Step 2: Putting Everything Together

Cut the bottle near the top, and drill a hole in the cover so the hose can come through. Leave a little bit of the bottle so it can cover the opening of the hair dryer. Connect the hose, pipe and the hair dryer and wrap the connections with the duck tape.

Step 3: Placing the Forge

Dig a channel in the ground the same length as the pipe, and place the pipe as on the photos (point the opening up). Cover it with stones or bricks to stabilize it and surround the place where the fire will be with the same material.

Step 4: The Problem

The hairdryer on the photos is the cheapest hair dryer from the Chinese store (about $2), and the problem is overheating so it melts the hose, the duck tape and even itself. I ordered online a new hairdryer ($20) that can blow air without heating and I will add more photos and a video tomorrow when it arrives. That is actually the only cost of this forge. I would just like to publish this instructable before the great outdoor contest finishes (tonight) and I will finish it tomorrow with the new hairdryer.

Step 5: The Imrovment

My new hair dryer has arrived so I made identical thing with the new hair dryer. I bought a 2000W hair dryer that has a switch for cold air (the highest button on the handle). I used a 0.5l plastic bottle and it fits perfectly to the hair dryer even without duck tape. This worked much much better, but I would still prefer to remove the heating element, so if someone has the idea how to do that without destroying the ventilator feel free to write me.

I also tried this with a vacuum cleaner (with the hose placed at the opposite side which is possible with some vacuum cleaners) and it also worked very well.

How well does your forge work because about to make one just like it
With another hair dryer that I used (the red one) it works well but the problem with hot air still remains. The button for cold air doesn't work as I thought. It would be ideal if you know how to disable the heater without destroying the ventilator, but I still didn't do that. Otherwise, it works very well, the hair dryer is strong enough to heat the iron, as I have shown in the video.<br><br>I hope this was helpful. <br>Regards.
I don't know how to disable the heating element unfortunately. Luckily my wife has a hair dryer that the heating element just quit working,so that's what I'll be using. Could you use a bigger pipe that so that the end of the hair dryer would fit in it directly. You wouldn't have to worry about anything melting.
<p>Thanks, if you know how to do that without destroying the ventilator you could make some instructable.</p>
if you are adventurous and know how you could simply disconnect the heatingelement from your cheap hairdryer...<br>you would dealing with mains-power. so only do it if you are qualified.
