Watch out with the bricks, some can't stand fast heating and can explode (not as in KABOOM! but it can cause the stove to colapse.. and red hot bricks are not a good alternative to toe nail clippers.. trust me, been there.. done that... got the tshirt to prove it)
@ Miguelovic, we build something similar as a lead stove (to cast slugs/bullets) but you could easily melt bullet lead over it (lead with a bit of tin and antimony for hardness). That stuff takes about 380 Celsius to melt properly without the antimony floating up (700 F). Later we used it for aluminium casting (2stroke tractor pistons) which needs 700 Celsius (1300 F), we then had to use antracite coal though.
It consisted of a cut open steel gas cylinder as the burn tube with those bricks build around it insulation with a bought heat proof fire ring. The gas cylinder had holes in it to feed new fuel (brown coal briquettes, peat, antracite, charcoal briquettes, beech wood etc). You didn't need a fan to blow the fire, the stove effect pulled the oxygen in causing a jet burn out of the fire ring.
It was a lot of fun until a some bricks cracked.. What do you do? Offcourse, you keep going.. it's ALMOST molten. Then a brick litterally exploded with a pop sound, the molten aluminium almost poured over my foot. Luckily just a little bit of brick.
So some wise advise;
Use proper bricks
Wrap them in chickenwire to prevent from collapsing
Make sure there is blood mixed in your alcohol and keep the ratios healthy.
