Hello. I have acquired an old Champion 407 forge and am restoring it, but oddly enough the forge has a circular firepot and a dish of sorts that sits in the middle of the firepot. I have not seen this anywhere on the net, including the Champion Forge History group. I am pretty sure the dish in the photo is a Champion item as it is heavy cast and has bolt holes that match up with the firepot and vent/clinker breaker underneath (see photo).
The question I have is if the firepot is supposed to be lined with clay-sand or refractory cement to the level of the dish OR should I just leave the dish out??
The other option--working with coal/coke under this dish does not make much sense.
I really hope someone can sort this out as I would really like to finish this thing and start using it. Thx.
