Electric Melting Furnace

Refractory this, refractory that (Oct 4th, 2004)
I've managed to ram the bottom of the furnace with the 1:4 high-temperature cement and perlite mixture. It's been curing for a while now and it seems to be quite solid. I think it will work. Now I have to cut some slots in the firebricks and ram some more refractory around them in the midsection ... then ram the lid with a small port in the middle.

I like how it looks so far. I opted for the thicker black furnace pipe rather than the thin duct pipe as is recommended in the plans. It looks more stealthlike. ; )

First shipment of gear (Sep 16th, 2004)
Yesterday I made a trip to a hardware store and a masonry supply store and acquired some of the starting materials to get the basic functioning unit of the furnace constructed.

Yeah, that's the stuff pictured to the right. Some firebricks, some high-temperature cement (two 1L pails), some black chimney ducting, masonry cutoff blades, 16 ga wire and finally, a big bag of perlite.

My friend saw the stuff and was amazed that I knew how to turn it into a kiln/furnace. I told her I didn't actually know how ... I just thought I did. ; )

We'll see.

Got the Plans! (Sep 11th, 2004)
I've got the plans from Dan and I've read them through and understand what I have to do. Next week I'll be acquired some of the materials and then I'll start building it. I found a place near where I live to acquire the specialty items, like firebricks that can withstand 2400F and special resistance wire to go that high as well.

I'll post an update when I have something to show.
Introduction (Sep 8th, 2004)
This summer I have been doing a lot of research into metalworking. I started with the idea of building a small CNC machine as an experiment and my dreams have now turned into having a full-blown metalworking shop. The first step into this realm, though, is to build an electric furnace.

I decided on electric because there is no exhaust gases. I found a guy who is selling plans on his website to build a furnace capable of 2400F, which is hot enough to melt brass, bronze, aluminum or glass. I plan to acquire the plans from him and build a furnace capable of those extreme temperatures to begin an interest in melting and casting my own materials.

I also found a guy on Mayne Island who uses a similar furnace for melting and casting glass. As long as I use the correct kind of crucible, it seems I'll be able to melt quite a few different things.

Right now I'm waiting for pay day so I can start acquiring materials to build this high-temp contraption. To be continued ...
