I fired it Saturday night (no camera though) to show a friend how it works. The wind was gusting 25+ and the temp was 80+ or so with 85% humiditity. I didn't figure it would even get up too temps since it was so warm outside. It quickly got up and rolling, zero smoke and good sideways fire in the feed tube. While it had been running for 15 minutes or so unattended we whent outside to check it out, the rh side of the burn tube was glowing red, I had never seen it do that yet and the radiating heat from the exposed portion of the burn tube was tremendous.
The heat from the bell was good too but I still wonder what it would be like with the correct gauge. I am going to build a 6" or 8" brick unit for my shop with the correct barrel, it is going to take quite a bit more output I think to warm it.
