Frosty, I'm finally getting my wool and refractory supplies shipped in. I'd love to run my ribbon in the same NARB fashion as yours. However, I have a tendency to over size things and my inlet for my block measures 4.25"x10.5". I'll definitely be testing with a wood block prior to casting. I'd like to leech off of your experience a bit. For that surface area would a single inlet for the plenum be sufficient naturally aspirated? Or am I probably looking at forced air or multiple inlets? I can supply concept renderings if it'll help, but I figure you won't need them.
