Thermolyne Electric Kiln Furnace 2000 deg F - $100 (watsonville)

I don't see any elements in it. Plus, a hole in the back of the bricks.
 
Same here- where are the elements? Kinda small capacity too
Pretty rusty 'n crusty
 
These old furnaces often require new elements, since the old ones have too much resistance and will not reach full temperature. The insulation in back is cracked off and needs repair. The hole is probably a gas port. It can be plugged with a kiln soft plug if not in use. That's what I do with mine.
 
To bad it is so faraway.
I could use one of those
 
That is a muffle furnace. The heating elements are wound between the honeycomb shape (newer) or voids behind of the refractory ceramic that lines it. That would probably make a great addition to the shop if it weren't for the total rebuild it would need. TBH, I'd be happy to take it if it were in my neighborhood. It'd be a project to gut it and put it back together refreshed. One might spend 2-3x again the purchase price making it right. It ain't much worse off than some that I've seen on CheeseBay for double the price.
 
To do a DIY het tret furnace you would spend more than that on just the fire brick, then still have to build a frame to go around it and a door with hinges and latch. This would make a great starting point to slap in all new electronics and be ready to go. Splash on a coat of paint and it will look like new.

If it were not so far away it would be sold by now.
 
That is still $5.40 each, the best price I have seen so far is 4.95 ea, To build an oven with a 9x9x18 inside would still take 30 bricks. That is still $150 the most expensive single component of the build.
