=================================================================

This is a simple idea for a Coal forge.

I built several of these years ago and they last forever. You 
can adjust the design any way you want to scale the firepot and 
table to any size you need.

The firepot is welded up from steel plate. The air blast is 
delivered through steel pipe.

You can either bolt or weld the pipe flange to the bottom of the 
firepot. If bolting use stainless steel bolts with high temp 
anti-sieze on the threads. The tuyere should just sit in the 
bottom of the firepot.

I suggest welding the heavy steel block to a thinner plate of 1/4" 
steel that matches the bottom of the firepot. This way if the tuyere 
needs to be worked on you can just lift it out. It's weight alone 
will keep it in the bottom of the firepot. The holes in the tuyere 
should be scaled to match the size of your coal chunks. I prefer 
almond to peach-pit sized coal.

The Clinker should end up as a donut around the bottom of the firepot.

Any questions can be sent to me.
