    Really nice work. Showcases what you can do with aluminum casting!

    Paint was a bad idea on the lifter because it will burn off an possibly make some smoke. Not a big deal, just ignore the smoke and pour! By the 3rd pour it will resolve itself.
    Good work so far. Get...

    Take note the IFBs come with temperature ratings from 2400 deg to 3000 deg. I would only use 2800 or 3000. The bricks above are only 2300 deg rated. That may be why the bricks fell apart especially...

    Interesting. If you look for Sioux tools on eBay you will see a lot of new air tools. Did someone buy the brand? There is an old drill and an angle grinder on there.

    The hard bricks are generally easier to find. They are very durable. They are heavy and hard to cut. They stay hot longer so require more time for the furnace to cool. Zappins approach would be fine...

    Richard makes a good point. Try a masonry or brick supplier. Not all Lowes have the firebrick. Mine does not. Keep in mind there are 2 types of firebrick. Soft insulating and hard brick. You could...

    You can go with castable. That is not wrong. But again, I think the insulating firebrick is way easier for a first furnace as well as being efficient and durable.

    A burner is not rocket science. If you are serious about copper alloys I think you will need forced air with propane. At least a small squirrel cage blower, nothing too powerful. All you really need...

    I did not degas not having any Cu phos. The small flat cylinder has some porosity in it. Not sure if gas or sand. The others appear to be good. The color looks great. I think I hit the mark pretty...

    Not a criticism but 2100 sounds too hot for regular pouring. 1900 tops. I'm glad you got a good result. Let see what HT says.
    I like the patina!

    Here's my two cents after pouring brass today: that crucible lift/pourer will be fine for aluminum. If you try that with brass your hand will catch fire inside the glove! I got a burn today through...

    I have coated 3000 deg IFB with ITC 100. It works fine and stabilizes the outer surface of the IFB to some degree. It makes it a little more durable. I don't buy the claims of increased efficiency....

    They are all damaged in some small way. So forgings are bad?

    Edit:
    Yes google says they are very similar to extrusions. Oh well. I will add them to some wheelium.
