treeclimber,
It looks like you are having a blast with this project! I wish I could be of more help, but you are in uncharted waters for my experience level. I just want to say that I'm enjoying following your progress and thanks for keeping us posted.
Colin

Thank you for the compliments. Some detail on the chip feed tube   I built it this way with air channels instead of simple slots like my test burner because the slots allowed a lot of fine stuff out on top of the burner. Note p channel on the front in the first picture. |

Here is the bypass door for exhaust to prime the chimney  Do you think it will warp badly? I put the rings on it in hopes of minimizing warping but I have my doubts about it. Of course it warped when I weld the rings on. It has about 1/8inch gap in the middle on the bottom. Is it important to have fairly tight fit? |

Is the bypass going right over the riser? If so, it's going to warp for sure. In my experience, it's not that important to have it seal tightly. The CSA of the gaps is so small that once the flow is going the right way it will follow that path. I have a bypass baffle on my outdoor cooking set up right over the riser, and once it's mostly closed it actually starts pulling in around the bypass.

It is off to one side a little below the top of the riser.

I was able to start working on my stove. I am working on the grate. since I have made the drawings I have decided that the grate that I drew will not work well at all. I am building the grate with small pipe for the down stream side and rod for the front. The idea is to keep the grate cool enough not to burn out and also to introduce super hot secondary draft. I will post some pictures later.

Here is my test grate. I am hoping air going through the tubes will keep it cool enough. Any ideas?   |

Test burn went well. I used Coleman fuel dumped on some chips to start. Once it started it never smoked at all except when I let it burn low before adding more chips. The only smoking it did was out of the vents on the feed tube, but when I closed the front up except for a small opening it built enough vacuum to eliminate this problem. It seemed to evacuate ashes pretty. It burned a lot longer than my test burner without clogging. I have one hair brained idea; why not use compressed air jetted towards grate to clear ash. Any thoughts?! One huge disadvantage is that it blows a lot of embers through the rest of system. We will see how the grated fared in the morning. It was very cherry red in places. I was hoping that the air going through the pipes would keep it cool enough, if I was to use stainless steel.  |

OK, this seems to be the number one problem, is ash clogging. It ran satisfactory for almost two hrs yesterday without any manipulation except to add wood chips. As you can see in the picture it is clogged with ashes. It even had a clinker on it, probably because there must be some poplar wood in the chips. If you have any ideas post them please, even if you think they are hair brained.  They may just help me think of something I have not thought of.  |

Tree climber we don't even see how that grate fits in your stove, unless there are more pics I can't see...

Tree climber we don't even see how that grate fits in your stove, unless there are more pics I can't see...  Front view (feed tube is removed look back a few post for side view) The square tube you see is supposed to draw cool air from the front and jet it through the pipes that make up the back part of the grate. This will hopefully keep them from burning up and also inject super heated secondary air. |
