After two years of mumbling and fumbling, lotsa procrastinating and tossing about, test has been done. Following Peter's recent development with the DSR

I thought kind of rotating his core was my best bet.

Tho, due to the hurry, i didn't cut firebricks, and measurements of the real one are on the sloppy side.

Hope you guys like it.

Just after lighting up, not much draw, due to the lack of insulation



Notice the speed of the flames?



 

Partially open, it doesn't smokes back much.



Fully open, it flames back.



No visible smoke.



And with the dimensions off, i still get the ram horns.

Well, that latest test was very good in my opinion.  No smoke, no overfueling. Pulsating a bit. So, i know i need a bit more air, primary air, i would think.

But this core seems to raise no interest whatsoever. I thought top load was really interesting. As i don't like to bend over to load the firebox. I get less surface for cooking, but it heats up faster. Only problems i see, the riser being real close to what would be the front of the bell. And the riser that i haven't managed to shorten yet.

If some are interested, please give me your opinion, i need feedback.

I like the hybrid of J-tube continuous feed and batch for cooking. I will be watching the progression of this design since I've got a batch rocket oven project or two in mind next summer.
 
Gravity is a harsh mistress. But this tiny ad is pretty easy to deal with:
