My first small engine run

Hello gasifier enthusiasts,
I got a start on my 26" cyclone project today. I extended the square gas outlet 2" and cut out a couple of square flanges for the “to be bolted” interface. I hung the cyclone in the preheat recovery shroud to get a sense of its tangential line up with the gas outlet. The tangential inlet to the cyclone will pass through the preheat shroud and will be welded to it in the final assembly, which will then bolted to the gas outlet flange.
The preheated air from the 4’ stove pipe around the S cooler sections(see 7/21/12) will be drawn in at the bottom of the cyclone shroud and end up entering the single port air inlet(Pic 4 above) as well preheated air.
