I use this fire a lot. It has a double side-draft firepot which I designed myself for a more even and controllable fire than is possible with the commercially available clinker breakers. There is a blower underneath the table which is belted to the line shaft, and there is a blast gate to regulate the air flow. This blast gate is controlled by one of two handles on either side of the forge, allowing me to work from either side, depending on which machine I am forging with.
