To quote the Iron Worker on THE SIMPSONS,  ”Hot stuff, coming through!”
I was pretty excited that I finally made it down to the Milwaukee Makerspace last night to attend an aluminum pour! I’ve seen a couple of the videos and really wanted to get in on some of that hot metal casting. I have what’s called a “speed-ring”, a metal ring that holds a soft-box for photographic lighting, and I wanted to make a copy of it.

So far, much of the casting has been using a “lost-styrofoam” method. A shape is carved from foam and set in sand, and the aluminum melts the foam as it’s poured in. But I wanted a COPY of an existing item. I asked Bret about it, and he said we could try an experiment of pretty much just pressing the ring down into some sand. An X channel was then added in the middle as a point for the aluminum to pour into and spread out into the shape.

I built a wood box for my item, and we filled it with oily sand, packed it in there, and added the X-trough. My item didn’t pull out of the sand quite as well as I had hoped, but hey, it’s an experiment…

Outside, the aluminum furnace was roaring away, heating aluminum to a delightful orange liquid. The first pour made it through Kevin’s FEAR art piece, my piece, and another members. Later, a second pour took care of Phil’s hand-casting series (which turned out great!)  and the rest went into an ingot mold.

Once my piece was cool enough, we pulled it out to take a look at the results. Not perfect, but not bad for a first time, and an experimental casting at that. There was quite a bit of extra metal, but most of that could be easily trimmed off with the bandsaw. Other members were taking photos of their work. It was obvious that everyone was pretty proud of their individual castings. Even without being the one pouring out twenty pounds of molten metal, it was still a pretty macho experience just to be part of.

If you too want to come play with crazy hot metal, come on down to the Makerspace next time we do an aluminum pour!
