    Build and first melt!

    Hello all,
    I made my first pour today, DAMN do I ever feel manly...

    I started putting my smelter together a few months ago. I did some research on the net and decided to go with a charcoal burning propane tank on a lawnmower deck. Thank you to all I borrowed ideas from... I displaced the tank with water, cut it and filled it with refractory mortar. I ended up getting busy and did not get a chance to fire it up for over a month. That was ok, plenty of time to cure in.

    Last week I did the burn in, didn't loose any insulation. I must admit I got a warm fuzzy when I hit the blower and the coals started really going. The blower is an old vacume I got for $3 at a thrift store and a dimmer switch I had replaced from the house. It works great.

    Yesterday I purchaced a 6" pipe nipple and a cap, schedule 40 black pipe 2.5" diameter, to use as a crusible. I had a couple old brass plumbing fuxtures from house repairs and decided to melt them down.

    Today I filled up with good old Kingsford and started in. What a learning experience... I started with only a little bit of metal in the crucible and added more when it started glowing orange. I was a bit too conservative with the air flow to start and had to refuel a couple times before I figured out it needed more air. Third times a charm, I just let her rip and next thing you know I had MELTED METAL WITH FIRE!(again, MANLY!) There was a LOT of sulphur residue and junk in the metal. I did not skim it enough and the pour was dirty. The other issue was what I poured it into, old, steel?, baking pan. It's stuck in there, will try to get it out again later. But I did a safe pour and am on my way with a bit more knowledge. Check out the pictures, fire is cool...

    Great show and tell post. Brass is tricky to cast, especially random scrap. Sometimes additives such as lead make it hard to get a good melt, and a lot of heat, flux, and skimming is usually required.

    You should try aluminum. It melts fast, pours nice, and you can pour into a muffin pan and have a pile of nice little ingots for future melting.

    Sound like your having a good time. We are building a smelting furnace using old truck brake drums. We were able to use a large metal lathe and machine them so they fit together. Now we just need to line it with fire brick or clay.
