Has anyone experimented with a round tapered riser? For example 48"high and 6" at the bottom and tapering out at an included angle of 6-10 degrees. I'm guessing the top would be 10-14" Diameter. Will the larger top create more flow at the bottom or not? It just has my cogs in my head turning! I may need to apply some WD-40 to them or just get some new cogs all together. I've always heard that curiosity killed the cat.

If the funnel start is the same dimension as the riser stub and the top is restricted back to riser size, it would work. I'd think it won't create more flow than a straight riser though. In case you mean tapering out from the very bottom to the top, I honestly don't know.

So staring out 6" At the bottom of the riser and steadily increase the diameter until the top of the riser.... ending up being a cone shaped riser. I did a video of my rocket stove with the primary air reduced, riser temps drop to 750-800F but I get much longer burn times. Thi is the link. Thanks for your advice youtu.be/JBpgDhYgIZ4
