I still have not decided if I want a gas or electric furnace. I am learning toward electric using this guys design:

It is October, time is running out. If I want cast this winter I need to get the furnace built.

Started collecting supplies at Home Depot today. Got the sheet metal and some of the hardware. May stop at Fleet Farm on the way home. I really have no idea where to find the high temperature furnace cement to make the refractory. Plans call for Black Meeco or Rutlland high temperature cement.

Then I need to locate a source for the fire bricks.

I picked up a dead kiln from a ceramics shop for $50. It had some elements in it but no brainbox. A whole lotta  bricks tho . New bricks go about $5 each plus shipping. Try your local craigslist but most I saw there were working units for $500ish. Be VERY CAREFULL if you go the route I did, the bricks are brittle and I lost a few taking it apart.

As Dan noted, his original model was the Gingery - Lindsay Books "Li'l Bertha".  One thing he did mention was that elements can be home-wound out of 0.045 stainless MIG wire.  I tried it, and it works well.  His work is pretty good, and his ideas do remedy some of the problems noted with the Gingery furnace.

Interesting about the MIG wire. Have you logged many hours using this as a heating element? I am curious of the longevity.

I've got a vat that uses one of these elements to heat oil for plastics melting.  Wound the element for it last fall, and it has perhaps ninety hours on it.  Elements are immersed in the oil, and take little or no wear from atmospheric oxygen.  I'll be melting more plastic this fall (now that things are started to cool down enough to make the shop bearable with this kind of heat input) and will keep you posted.
