    .....only catch is you have to come get them at 52722 zip, Bettendorf, IA. I just don't have room to store them.

    This is a 14" bore, 19" tall, dense castable hot face with insulating castable structure, ceramic fiber insulated, sheet metal skin. It was built to used as a fuel fired lift off furnace but could be used as is as a lift out furnace, but would need a lid lifter. It's OD is 22" and will slide into a 55 gal drum which was basis for my lift mechanism (not included). This is about the lowest mass dense castable hot face furnace you'll find in this size. I recently converted my large furnace to resistive electric and don't have the space to store this one.

    Though not included for free, I also have an 8kw electric insert and controller that I may part with for a price. This furnace has only seen resistive electric duty for about 100hrs at 1800F, so the 2800F refractory is well cured but not fully cured.

    Also available is the dense refractory insert for my smaller 8kw resistive electric furnace. Like above, it was designed to be used in a lift off furnace but could be used as lift out. It still has two functioning 4kw heating elements installed and was powered by the same controller mentioned above. It still has IFB refractory in the base and will slide into a 16"D 30 gallon barrel. If you made a castable refractory base with Tuyere, removed the coils, it could be used as a fuel fired furnace.

    Interested parties PM me. First come first serve. I figured I'd offer here before I punished myself with FBMP.

    Well, the stars finally aligned, or at least the two of us being in the same state at the same time (non quantum wise). It was a beautiful Saturday drive out to the Mississippi river, and when I pulled into the neighborhood, I exclaimed, that driveway looks familiar. Kelly was good enough to give me and my son a tour of the place and talk shop for a bit. Some things looked bigger in real life (like the claws for the big crucible), but boy his shop was packed full of stuff. I can see why he wanted to get rid of the extra furnaces.

    So now I have a dense electric furnace, with four wires hanging out the side that I have to wire up. And my buddy has a new shell for his plans to do some backyard fuel firing. It rained all day Sunday (and it was Easter), so no progress yet, but hopefully pictures and firing to happen soon. Though I do need to make some crucible tongs.

    Thanks again for the units, I hope I do them proud.

    Nice to meet you and your son Derek. Thanks for making the drive and hope you are able to get some use out of them.

    Best,

    Glad to see it went to a good home, hope we'll get to see it in action soon...
