A charcoal forge for casting aluminum electrodes and casings can be produced from a blow dryer and some clay bricks. Aluminum scrap comes in a range of forms, Mostly involving harmful particles of one form or another. This scrap can be lowered to (automobile) Pure material oxide (What we commonly call aluminum can be aluminum oxide) By smelting it and taking out the impurities which float to the top. The molten metal can then be cast into forms which are convenient for use in low and medium voltage al air or al oxide energy generation systems and various casting applications.
Unlike many other forges this one can be reasonably used in a household environment without attracting undue attention from the neighbors. It’s not rather noisy and doesn’t project huge fiery jets. It doesn’t require permanent construction or a specialized system. It can be constructed, Used and torn down in a single afternoon.
everyone loves many of the propane designs I saw but most people don’t have a propane burner or nozzle assembly to spare so I decided that design which leveraged existing BBQ technology would be more widely useful.
the mandatory note: I believe the insurance underwriter add that says 25 burned down their houses attempting to deep fry turkeys. you shouldn’t be an idiot.
No hair dryers were injured in the making of this instructable if would be nice if folks who tried this exercised great care and caution and no humans get injured in trying to do this.

As promised in the title the key are products are common red clay bricks and a household blow dryer.
you have to pick:
23 good red clay bricks. I had some used brick scattered about but new brick from Home Depot costs about 17 cents each. You can get firebrick in order for you (i didn’t). The concrete bricks could be okay but I can’t speak to that.
the same old boring blow dryer. You can pick up a cheap one at Walmart or Target for around $15 or you can use on there is. It will not be damaged or changed in using this method.

A BBQ grill at 18 inches in size. When all was said and done I used best grill from my Weber, You will learn more about this decision in the next step.
charcoal or biochar briquets, The charcoal must be completely formed to rest on the fire grill.

chrome effect can. I became of to use Rosarita Refried Beans, This is a standard super market can size and almost any 30oz can should do. A small size may be used but for this design the 30oz is appromiximately the biggest size that can be accomodated.
A catalog or interesting, work with slick, modern pages ( Clay newspaper ). We actually only need one page from it which will be damaged during this process.
A long handled tea spoon or small ladle for taking off slag.
A 1 foot or so piece of steel pipe of approximately the same diamater as the blower tube on the blow dryer is best. Different diameter pipe can be utilized but if so a smaller diameter wholesale discount jerseys should be chosen.
A 2 foot or so wooden stick or pole to use in handling the crucible.
A can operator. I didn’t show all the tools needed but I’m showing the fancy, Shmancy one i do have.
Okay now if we have got all the bits together let’s make a furnace.

Here you see the basis of the forge. The forge really should be placed on open ground away from burnable material. It doesn’t radiate considerably heat but could easily catch the grass on fire, that kind of thing. The best thing would probably be a bed of sand if you have some.
The bricks are layed out to create an air chamber the strength of, skillfully, One bricks. The pipe fits loosely between its guide bricks and will be removed momentarily in a later step.
This unit serves to isolate the forced air feed (blow dryer) From the warmth of the fire. Since heat goes up the air feed and hair dryer are placed below the burn chamber. this excellent, in combination with the forced air assembly insulation seems to protect the device adequately.
Note how the pipe just initiatives into the chamber. I experimented with various things and it seemed wholesale nba jerseys like this assembly got wholesale China jerseys the most even air flow through the firebox.
This layer may even hold the fire grill. The firebox sits above the air chamber and the grill used to support the charcoal in pace. My grill had a supporting wire rod running down the center so you will see how I used the recess created by the pipe and the gap between the two bricks in the back to so that it lays flat and doesn’t get bent by the weight of the bricks above. I used a grill big enough so the outer wire supporting rod didn’t impact the forge. Ever
